All details contained in this documentation are subject to change without prior notice. TERRATEST GmbH gives no assurance as to the accuracy of this documentation, and specifically disclaims any implied warranties of merchantability or fitness for a particular purpose.

TERRATEST GmbH cannot be held liable for errors contained in this documentation, or for accidental or sequential damage in connection with the delivery, performance, or use of the material.

PLEASE OBSERVE THE INSTRUCTIONS OF THE GERMAN STANDARD ‘Technical Test Code for Soil and Rock Mechanics in Road Construction TP BF-StB Part B 8.3’.

Evaluate the test data strictly in accordance with ZTV-E, ZTV-A, RIL 836 and/or RVS 08.03.04.

We would like to point out explicitly that a reliable evaluation of the test data is only possible if a correlation measurement with the static plate load test is performed for every dynamic test with the Light Weight Deflectometer. At least three static plate load tests should be performed for a reliable calibration (see p. 29/30).

1.2 General Safety Information

Please read and understand the following safety guidelines, before starting to use ‘TERRATEST 4000 USB’ / ‘TERRATEST 5000 BLU’.

Useful information and instructions

ATTENTION

Indicates processes where incorrect execution could result in physical injury or material damage. Please observe these warnings carefully to ensure a safe operation of the device.

ATTENTION If the Light Weight Deflectometer is used in a manner not specified by these instructions, the protection provided by this instrument may be impaired.

ATTENTION (Quotation from ZTV E-StB 09) ‘The deformation modulus Ev2 is to be assessed by the static plate load test, in accordance with DIN 18134, and the dynamic deflection module Evd with the dynamic plate load test, in accordance

with TP BF-StB Part B 8.3.... The specifications of the building contract should state whether the static or

dynamic deflection modulus is to be established. If no such statement is to be found in the contract, the static deformation modulus will need to be established.’

ATTENTION The evaluation of the measured Evd value depends on the material and the subsoil being tested. It is always necessary to determine correlation values of the static plate load test on a trial basis for the pre-existing ground or the ground intended for backfilling. Homogeneous ground is a prerequisite for properly correlating the two measuring methods. Accordingly, the water content of the soil must not vary widely.

ATTENTION According to German standard TP BF-StB Part B 8.3, Light Weight Deflectometers must be calibrated at least once a year at a calibration institute accredited by the German Federal Road Research Institute (Bundesanstalt für Straßenbau). Test results of a device that has not been calibrated or of a device with an expired calibration date must not be used for evaluating the bearing capacity of soil or rock. Abide by the mandatory calibration intervals.

CAUTION

Never place the testing computer or load plate of ‘TERRATEST 5000 BLU’ near any inflammable liquids such as alcohol, thinner etc. There is a risk of fire if such flammable liquids make contact with the electric components in the interior of the device.

CAUTION

Never place or charge the testing computer or load plate of ‘TERRATEST 5000 BLU’ in areas with excessive humidity, high temperatures, direct sunlight, or close to open flames. Doing so carries the risk of fire or electric shock.

CAUTION

Whenever the loading device is not placed on the metal ball of the sensor dome on the load plate, always store it horizontally or on the magnetic plate, which may be purchased separately. The loading device could fall over and cause injuries otherwise.

CAUTION

Before operating the Light Weight Deflectometer read the instruction manual carefully to ensure correct set-up of the device. When no test is performed, keep the drop weight in its ‘rest’ position at the bottom of the guide rod. The drop weight could fall down and cause injuries or damage otherwise.

1.3. Safety Precautions during Power Supply

CAUTION

Never place any heavy objects on the measuring or charging cables. Never twist or pull them, and take care that they do not become knotted.

CAUTION

Ensure that the charging and measuring cables are fully inserted into their sockets. A poor connection can lead to equipment damage. Use only the cables provided.

1.3.1. Power Supply

ATTENTION

Only batteries approved by the manufacturer (Panasonic LCR-6V 4.2 P) should be used for the testing computer. Batteries should only be replaced and disposed of by qualified personnel. The plugs of the cable, to which the battery will be connected, are colour-coded. The white wire with the red plug should be connected to the positive (+) pole of the battery (+6 volts). The brown wire with the black plug should be connected to the negative (-) pole of the battery. The cable contains a 2A/32V fuse.

Only the permanently-installed, long-lasting, rechargeable battery pack approved by the manufacturer

(type 8904 7.4 V/2.4 Ah) should be used in the Bluetooth

sensor dome (‘TERRATEST 5000 BLU’ ONLY).

This battery pack should only be replaced by the manufacturer.

ATTENTION

The assembly may be destroyed if the leads of the battery are interchanged, or a different type of fuse is inserted.

No tests should be performed while charging the device.

1.3.2. Mains Power Supply

ATTENTION

Only power cables approved by the manufacturer (SA07-15US12R) may be used for the testing computer. When using the power cable to charge the device, take care to do so only in dry, indoors locations. The inner pole is the positive (+) pole.

Only power cables with LEMO-plugs approved by the manufacturer (SYS1308-1809-W2E) should be used

for charging the Bluetooth

transmission unit in the Bluetooth®sensor dome (‘TERRATEST 5000 BLU’ ONLY). When using the power cable to charge the device, take care to do so only in dry, indoors locations. The inner pole is the positive (+) pole.

1.3.3. Car Charger Lead

4.3 Dynamic Plate Load Test

The dynamic plate load test with the Light Weight Deflectometer is a test method during which the ground is subjected to an impact load. This impact load is caused by a weight dropping onto a load plate with a diameter of 30 cm (radius r = 15 cm), which generates a maximum force (F calibration of the device this force is adjusted so that the normal stress (σ

) of 7.070 kN. During

4.4 Area of Application

The dynamic plate load test with the Light Weight Deflectometer is suitable for testing the bearing capacity and the compaction of subsoil / soil on the subbase of earthworks and road constructions. ‘Soil’ shall be understood as including backfill materials, base courses without binding agents, soil improvements, cold recycling layers, mineral sealing layers, asphalt and cement, which has yet to set. The testing method is especially suitable for coarse-grained and mixed soils with a maximum grain size of 63 mm.

The test can be performed in less than two minutes by a single operator, without a load testing vehicle. Thus, it is possible to immediately evaluate the evenness of the bearing capacity within the inspection lot.

In Germany and Austria the dynamic plate load test may be performed as an alternative to the static plate load test according to DIN 18134.

The use of the Light Weight Deflectometer always requires a prior determination of correlation values with the degree of compaction or the deformation modulus. The evaluation of the measured Evd value depends on the material and the subsoil being tested. It is always necessary to determine correlation values of the static plate load test on a trial basis for the pre-existing ground or the ground intended for backfilling. Homogeneous ground is a prerequisite for properly correlating the two measuring methods. Accordingly, the water content of the soil must not vary widely at the different testing points.

ATTENTION (Quotation from ZTV E-StB 09) ‘The deformation modulus Ev2 is to be assessed by the static plate load test in accordance with DIN 18134 and the dynamic deflection module Evd with the dynamic plate load test in accordance with TP

BF-StB Part B 8.3.... The specifications of the building contract should state whether the static or dynamic

deflection modulus is to be established. If no such statement is to be found in the contract, the static deformation modulus will need to be established.’

One advantage over the static plate load test according to DIN 18134 is the possibility to perform tests in confined areas such as utility trenches or construction backfills.

In accordance with the German standard TP-BF StB Part B 8.3 the measuring range of a Light Weight

Deflectometer with 10kg drop weight must be specified as 15 MN/m

to 70 MN/m2, since it is only within this measuring range that the device complies fully with the strict rules of the German Federal Road Research Institute (Bundesanstalt für Straßenwesen).

4.5 Calibration

Before delivery ‘TERRATEST 4000 USB’ and ‘TERRATEST 5000 BLU’ are calibrated according to German ‘Technical Test Code for Soil and Rock Mechanics in Road Constructions TP BF-StB Part B 8.3’. During calibration all components of the device, such as the load plate with integrated sensor, the loading device and the electronic testing computer, are attuned specifically to one another. After successful calibration, respective calibration tags with the expiry date of the calibration are affixed to the load plate, the loading device, and the testing computer. These calibration marks also contain the name of the calibration institute and the serial number. Each device is provided with a calibration certificate which meets the requirements of the German standard TP BF-StB Part B 8.3. A precise test result can only be guaranteed if the device is used as a single unit with all its corresponding parts. Identification plates with the same four-digit serial number are located on the load plate, the drop weight and the testing computer for this purpose. This serial number is also recorded on the calibration certificate. On the identification plate of the drop weight the date of the last calibration and the respective drop height of the weight in cm are also noted.

According to German standard TP BF-StB Part B 8.3 the device must be calibrated at least once a year at a calibration institute accredited by the German Federal Research Institute (Bundesanstalt für Straßenwesen).

Test results of a device that has not been calibrated, or of a device with an expired calibration date, must not be used for evaluating the bearing capacity of soil and rock. Abide by the mandatory calibration intervals and ensure that the device is re-calibrated in due time.

4.6 12 Rules for Proper Use

1. Always perform a correlation measurement with the static plate load test. For every static plate load test at least three dynamic tests must be performed.

2. The section examined by the device reaches down to a maximum of 40 cm in depth, depending on backfill materials and subsoil.

3. Remove any loose material from the test area; create a smooth and level surface on which to place the load plate. Ensure full and even contact between the load plate and the ground. In the case of soil irregularities, spread a thin layer of sand on the surface and reduce the thickness of the layer by moving the plate back and forth.

4. Keep the guide rod vertical and make sure that the plate does not move horizontally during the impact.

5. ATTENTION: The transportation lock must be unlocked before each drop. Catch the weight on the side opposite the lock. No warranty for damages caused by improper use.

6. The decline of the test area must not be greater than 6°.

7. Pull on the plugs only, never on the measuring cable!

8. Never change the position of the release handle!

9. Before each test, make sure that the bottom side of the plate is clean and remove any material stuck to it.

10. The grain size of the material to be tested may be a maximum of 63 mm.

11. If the three settlement curves vary widely, re-compaction has occurred caused by the test.

12. Make sure that latching the drop weight into the release mechanism does not trigger an accidental reading of the testing computer.

Only transport the loading device when the drop weight is in its ‘rest’ position at the bottom of the guide rod and the transportation lock is locked. Any other way of transport is prohibited, and carries with it considerable risk of accident due to the movement of the drop weight.

4.7 Proposal for the Correlation of Static / Dynamic Plate Load Test

The static and the dynamic plate load test differ from each other especially in the load speed and the pressure exerted on the ground. Therefore there is no constant correlation between the parameters Ev1/ Ev2and Evd.

In order to achieve the most accurate reading possible, we recommend performing site-specific correlation tests for every construction project directly on-site. To determine correlation values for the required backfill material we advise you to adhere to the following procedure: After the first phase of compaction work has been sufficiently completed, perform a static plate load test on the test area. Make sure that the loading vehicle leaves the area very carefully to avoid any ground disturbances. Afterwards, determine the water content of the backfill material. Then, in a circle around this first testing point, carry out eight dynamic plate load tests – four tests 30 cm away from the first testing point, and four 60 cm away, each with a 45 degree distance from the next. Several test sequences must be performed in succession along the centre of the compaction line; the required number depends on the size of the construction site. In all cases, at least three test sequences, at a distance of 20 metres from each other, should be performed.

The procedure must be repeated at other points of the test area. If the water content at the different testing points does not vary widely, compare the mean values of the measured Evdvalues with the mean values of the Evvalues obtained through the static test.

For the calculation of the Evdmean value, ignore the two highest and the two lowest test results and consider only the four test results which show parameters close to each other. After having determined the correlation values Evd/ Evall other tests can be performed with the Light Weight Deflectometer, provided that it is used on the same type of soil. Contractor and client should perform the correlation procedure together, so that they can both agree on the standard test method.

4.8 Interpreting the Test Results

According to German standards ZTV E-StB 09, ZTV A-StB 12 and RIL 836 Deutsche Bahn AG as well as Austrian standard RVS 08.03.04, an inspection with the dynamic plate load test (in accordance with ‘TP BF-StB Part 8.3 for Soil and Rock Mechanics in Road Constructions’) can be conducted instead of the static plate load test. Please strictly follow the instructions of ZTV-E, ZTV-A and/or RVS 08.03.04 (Austria).

For every static plate load test at least three dynamic tests must be performed. However, these must not be conducted side by side, but can be spread over the entire test area.

The evaluation of the measured Evd value depends on the material and the subsoil being tested. It is always necessary to determine correlation values of the static plate load test on a trial basis for the pre-existing ground or the ground intended for backfilling. Homogeneous ground is a prerequisite for properly correlating the two measuring methods. Accordingly, the water content of the soil must not vary widely.

BF-StB Part B 8.3.... The specifications of the building contract should state whether the static or dynamic

deflection modulus is to be established. If no such statement is to be found in the contract, the static deformation modulus will need to be established.’

According to German standard TP BF-StB Part B 8.3 Light Weight Deflectometers must be calibrated at least once a year at a calibration institute accredited by the German Federal Road Research Institute (Bundesanstalt für Straßenbau). Send the device back to TERRATEST GmbH for calibration at least once a year, otherwise test results may be imprecise. Test results of a device that has not been calibrated, or of a device with an expired calibration date, must not be used for evaluating the bearing capacity of soil and rock. Abide by the mandatory calibration intervals.

For general information only! All details are subject to change.

Always perform a correlation measurement with the static plate load test, before evaluating the test results.

The water content at the different testing points must not vary widely.

For every static plate load test at least three dynamic tests must be performed.

TERRATEST GmbH shall not be liable for any damage, consequential damage, or even financial loss that occurs as a result of improper use of the device and / or lack of professional knowledge when evaluating the test data. It is essential to ensure that the calibration of the device is always up to date, and that the device is always operated in accordance with the instructions of this document as well as your local standard.

4.9 Determining the Residual Compaction

If three individual curves are shown on the protocol printout (see Figure 1) and if the Smax value of the individual settlements decreases significantly, re-compaction has occurred caused by the test; further compaction work is usually necessary. In this case we recommend improving the compaction at the same place by performing 15 more impact drops with the Light Weight Deflectometer. Afterwards, repeat the compaction test. If the distance between the individual curves decreases, in the ideal case only one single curve composed of three congruent curves will be shown (see Figure 2), one can conclude that the ground can be further compacted without difficulty, due to residual compaction.

Figure 1: Test performed on relatively soft soil with visible re-compaction by the dynamic plate load test. Three individual curves are shown.

Figure 2: Test performed after 15 re-compacting impact drops with the Light Weight Deflectometer at the same testing point: The protocol printout shows a single settlement curve composed of three congruent curves. The Evd value, and thus the bearing capacity of the ground, has increased by 20% compared to the first test.

Further compaction work should be considered for this test area.

5. Test Execution ‘TERRATEST 4000 USB’ (for ‘TERRATEST 5000 BLU’ see page 38)

5.1 Preparing the Testing Point

Place the load plate on the ground, ensuring full and even contact between the load plate and the ground. Create a smooth and level surface on the area where the load plate will be placed. This can be done by moving the load plate back and forth, or by using appropriate tools (such as a trowel). Remove any loose soil from the area. In case of soil irregularities, spread a thin levelling layer of fine-grained quartz sand. Make sure to add only a few millimetres; it should compensate only for uneven patches under the load plate. Next, place the load plate on top and move it back and forth to reduce the thickness of the sand layer. Full contact between the load plate and the test area is essential.

5.2 Test Execution / Data Input Function

After preparing the testing point and placing the load plate on the ground, place the loading device in the centre of the sensor dome on the load plate.

Connect the sensor dome of the load plate with the testing computer, using the measuring cable.

Press and hold the start button to turn on the testing computer. To activate the backlight of the graphic display, press the start button for approximately three seconds, when turning on the device, until the start screen switches automatically to ‘STATUS REQUEST’.

When turning on the testing computer with the backlight off, the start screen will show the ‘TERRATEST 4000 USB’ logo and the firmware version number for approximately three seconds, before it switches automatically to ‘STATUS REQUEST’.

During ‘STATUS REQUEST’ the computer checks the sensor connection, USB stick, GPS, and the current battery charge, and confirms that everything is working correctly by showing ‘OK’. If one of these features is unavailable, a ‘ ? ‘ will be shown instead. Checking the GPS connection can take 2-3 minutes. If the sensor connection is not established, the computer will not progress to the measuring mode and no test can be performed. The current battery charge is shown as a small battery icon, indicating the current level of charge.

If the USB stick is not recognised, turn the device off, insert the USB stick again and turn the device back on. If the USB stick is still not recognised, check that it has been formatted correctly. The USB stick can be formatted on a PC by choosing ‘format...’ from the context menu which appears when right-clicking on the drive icon.

After placing the loading device on the metal ball in the centre of the sensor dome, unlock the transportation lock of the drop weight by pulling the orange knob. The transportation lock should only be unlocked immediately prior to a test being performed, as uncontrolled movements of the weight may cause injury or damage to the device or its surroundings.

Ensure that the transportation lock is unlocked before each drop.

In case of improper use, i.e. if the weight is dropped while the transportation lock is still pushed in, damage to the device may occur. Damage caused by improper use is not covered by the device warranty.

Regularly check that the transportation lock of the drop weight is functioning properly. If you notice signs of wear, stop using the device immediately. Send the device back to TERRATEST for the transportation lock to be repaired or replaced.

Put on hearing protectors before the first drop. Hearing protectors must be

worn when operating the Light Weight Deflectometer, since the noise level may rise over 85 dB during the test. ATTENTION: Operating the device without hearing protection can result in permanent hearing impairment.

Following the instruction on the display ‘10 kg 1. Preload’, continue with the first pre-consolidation test as follows: Take hold of the blue safety grip at the end of the guide rod; open the release mechanism by pushing the green start lever towards the guide rod and holding it there. With your other hand pull up the unlocked drop weight all the way until it stops. Fix it in place by releasing the green start lever and thus latching the drop weight into the release mechanism. The drop weight is now fastened securely in the release mechanism on top of the device. Open the release mechanism by pushing the green start lever towards the guide rod, and let the drop weight fall freely until it hits the spring assembly. Catch the drop weight immediately after first contact and in the same way as described above, latch it back into the release mechanism. In total, six drops must be performed to complete the test.

After hearing the audio signal and receiving the instruction ‘10 kg 2. Preload’, continue with the second pre-consolidation test in the same way as described above. The testing computer will not register any drops performed before the audio signal.

A longer audio signal (a beep lasting one second) announces the end of the test and the recording of measured data on both the internal memory and the USB stick (if in use). All test data including settlement curves, GPS coordinates, date, time, serial number, device type, and the test results themselves, are now saved. The protocol can be printed by pressing the ‘PRINT’ button. Alternatively, continue with the next test by pressing the ‘START’ button (NEXT) again.

Keep the safety grip on top of the device tight in your hand during the whole test. When a test is not being performed, never leave the weight latched on top of the loading device, as it could fall over and cause injury or damage. The drop weight should only be latched on top of the device immediately prior to an upcoming test. While in use, only the operator should come close to the device. All other persons should stay at a safe distance to ensure that no one is injured by the dropping weight. After the sixth drop place the drop weight in its ‘rest’ position on top of the bellows at the bottom of the device and lock it immediately with the transportation lock.

Ensure that the guide rod is kept upright during the impact. Use the spirit level integrated in the safety grip to aid in the vertical positioning of the guide rod. The test is invalid if the load plate moves horizontally during the impact. This risk exists particularly if the test area is inclined. Avoid sideward movements of the load plate on inclined test areas by placing your foot against the side of the plate. Never stand on the plate! Doing so will distort the test results. Every correct impact will be acknowledged by an audio signal (a single beep).

A different signal (a stuttering beep) will announce a possible measuring error. In this event, ‘Try again’ will be shown on the display. Should this occur, move the load plate and restart the complete test from the first pre-consolidation drop.

If the error message shows again, the soil may be too soft or too hard, so that the measured value is outside the measuring range. In this case, move the load plate to another testing point and repeat the test there.

The sensitivity of the testing computer is set up in such a way that a normal placing of the loading device on the load plate, or a normal latching of the drop weight into the release mechanism will not trigger a measurement.

However, abrupt movements when placing the loading device on the load plate, or latching the drop weight into the release mechanism, may trigger an impulse. The electronic plausibility check will recognise the error and the device will restart the complete test. Move the load plate and start the test procedure again from the beginning.

If the settlement is very small, it is advisable to push the loading device onto the metal ball of the sensor dome during impact. Doing so will help to avoid a possible rebound of the guide rod and thus a distortion of the test results.

Try again !

5.3 Printing the Test Protocol

The integrated thermal printer allows printouts of the test protocols to be created conveniently on-site, immediately after the test; protocols can also be printed at any later point in time. The protocol shows all data obtained during the test (see printout on page 37). To print the test protocol, activate the thermal printer by pressing the ‘PRINT’ button. It is located on the internal control panel. During the printing process the control lamp will show green. When printing is finished, detach the protocol by tearing it against the tear-bar. If the green light is flashing and the thermal printer does not start printing after pressing the ‘PRINT’ button, this is usually due to the absence of paper. In this case, follow the instructions below to insert a new roll of paper. The button for the paper feed is located on the left of the green control lamp.

5.4 Changing the Paper

A flashing green control lamp signals the absence of paper. To open the paper tray and replace the paper roll, press the button on the green control lamp. Lift the cover and insert the new thermal paper roll (57 mm wide and 25 mm long) with the coated side facing outwards. One roll of paper will print approximately 100 printouts. Unroll approximately 10 cm of the edge of the paper and hold it up, while closing the printer by gently pressing the cover on both sides. Detach the protruding end of the paper by tearing it against the tear-bar. The printer is now ready for use again. An ink ribbon is not necessary for the thermal print method.

Use only thermal paper; the coated, heat-sensitive side must face outwards. Suitable paper rolls can be obtained in most office supply stores, or ordered at TERRATEST GmbH.

6.3 Connecting Bluetooth®Load Plate to Testing Computer

with the Measuring Cable

If the Bluetooth®connection between Bluetooth®load plate and testing computer is not desired, or not possible, the connection can also be established with the supplied measuring cable. Turn on the transmission unit of the Bluetooth®sensor dome by pressing the button on the Bluetooth sensor dome. The status LED will show red, indicating that the device is ready for use. Turn on the testing computer and connect the Bluetooth®sensor dome on the Bluetooth®load plate with the testing computer by using the measuring cable. Be careful when opening the hinged lids of the sockets and when inserting the plugs. If the connection has been successful, the status LED will turn blue. You can now start the test. The high-quality PUSH-PULL plugs from LEMO lock themselves inside the socket automatically and can be unlocked only by gently pulling on the connector housing. Accordingly, never pull the cable. Doing so causes damage to the cable and the device. The plugs of the measuring cable are identical, making an incorrect connection impossible.

Control elements of the

Bluetooth

sensor dome

6.4 The ‘Magic Eye’ of the Bluetooth®Sensor Dome

The Bluetooth®transmission unit of the Bluetooth®sensor dome is equipped with a status LED, which indicates three different states. During the test, these are displayed via the ‘magic eye’ (a transparent hemispherical cover over the transmitter) on the Bluetooth®sensor dome.

‘Magic Eye’ RED

After turning on the transmission unit by pressing the button on the Bluetooth®sensor dome, the ‘magic eye’ will show red, indicating that the device is ready for use. In this state, the Bluetooth®sensor dome is waiting for the connection with the testing computer to be established. If the ‘magic eye’ switches to red during the test, it indicates that the Bluetooth®connection between the testing computer and the Bluetooth load plate has been lost. This may be caused by the distance between the Bluetooth®load plate and the testing computer being too great. In this case, testing stops and the voice output of the testing computer will issue a sonar signal, indicating that the testing computer is attempting to re-establish the connection. Reduce the distance between the Bluetooth load plate and the testing computer. Another possible cause for the failure might be that the automatic switchoff mechanism of the testing computer has turned off the computer after three minutes of inactivity. In this case, turn the testing computer back on and wait for the connection to be re-established. If the Bluetooth®connection has been successful, the voice instruction will announce ‘BLUETOOTH OK – START TEST’.

‘Magic Eye’ BLUE

If the Bluetooth®connection between the testing computer and the Bluetooth®load plate has been successfully established, the ‘magic eye’ will show blue. The voice output of the testing computer will also indicate the successful connection by announcing ‘BLUETOOTH OK – START TEST’.

Always ensure that the ‘magic eye’ faces towards the testing computer, so that there is a line of sight between the two.

‘Magic Eye’ BLUE: the connection is established

‘Magic Eye’ GREEN

Whenever the Bluetooth®sensor dome is ready to start a test, the ‘magic eye’ will show green. After every drop the test data will be transferred to the testing computer. During data transfer the ‘magic eye’ will switch to blue. As soon as the data transfer is finished the ‘magic eye’ will switch back to green, indicating that the device is ready for the next drop.

‘Magic Eye’ GREEN: ready to start a test

6.5 Continuous Measuring Mode

If the test shall be performed on several testing points close to each other, the testing computer can be operated in ‘CONTINUOUS MEASURING MODE’. In this mode tests can be performed in quick succession, without the need to operate the testing computer between each individual test.

To turn on the ‘CONTINUOUS MEASURING MODE’, press the ‘SELECT’ button during ‘STATUS REQUEST’. In the ‘MAIN MENU’ press the ‘SELECT’ button, until the arrow is positioned on the menu entry ‘CONNECTION’. Then press the ‘START’ button to select the menu ‘CONNECTION’. Finally, press the ‘START’ button again to select the menu ‘STAND-BY TIME’.

The stand-by time is the time that the testing computer will wait for the next test to start before switching itself off due to timeout. Use the ‘SELECT’ button to increase the wait time by increments of five minutes, up to a maximum wait of 30 minutes. Confirm the set time with the ‘EXIT’ button. Continue pressing the ‘EXIT’ button, until the screen shows ‘STATUS REQUEST’ again. Then start the first test, as described above. The voice output will confirm if the ‘CONTINUOUS MEASURING MODE’ is turned on successfully by announcing ‘CONTINUOUS MEASURING MODE ON’. It will then direct you through the test, as described above.

6.6 Printing the Test Protocol

The integrated thermal printer allows printouts of the test protocols to be created conveniently on-site, immediately after the test; protocols can also be printed at any later point in time. The protocol shows all data obtained during the test (see printout on page 45). To print the test protocol, activate the thermal printer by pressing the ‘PRINT’ button. It is located on the internal control panel. During the printing process the control lamp will show green. When printing is finished, detach the protocol by tearing it against the tear-bar. If the green light is flashing and the thermal printer does not start printing after pressing the ‘PRINT’ button, this is usually due to the absence of paper. In this case, follow the instructions below to insert a new roll of paper. The button for the paper feed is located on the left of the green control lamp.

6.7 Changing the Paper

A flashing green control lamp signals the absence of paper. To open the paper tray and replace the paper roll press the button on the green control lamp. Lift the cover and insert the new thermal paper roll (57 mm wide and 25 mm long) with the coated side facing outwards. One roll of paper will print approximately 100 printouts. Unroll approximately 10 cm of the edge of the paper and hold it up, while closing the printer by gently pressing the cover on both sides. Detach the protruding end of the paper by tearing it against the tear-bar. The printer is now ready for use again. An ink ribbon is not necessary for the thermal print method.

Use only thermal paper; the coated, heat-sensitive side must face outwards. Suitable paper rolls can be obtained in most office supply stores, or ordered at TERRATEST GmbH.

The device is delivered with the status set to ‘GPS IS ON’.

The GPS reception is automatically activated when turning on the device, unless it has been switched off previously. After turning on the device,

6,3V 100

GPS

GPS AVAILABLE

If a test is started without waiting for GPS reception during ‘STATUS REQUEST’, the GPS will not log in and all tests will be performed without the GPS function.

If the GPS reception is turned on, the GPS coordinates of the testing point will automatically appear on the test protocol. They will also be saved automatically to both the internal memory and the external

media (if in use) for later analysis on a PC and connection to the Google

Maps interface.

7.5.2 Accuracy of GPS Reception

The GPS satellite positioning system was developed by the U.S. Department of Defense at the beginning of the 1970s. 24 satellites were placed in space. Due to the orbits of the satellites and the deployed transmission technology, the accuracy of the determined position is limited.

We would like to briefly explain this further: A GPS receiver calculates its position by analysing the signal of several GPS satellites. The more satellite signals it receives, the more accurate the determined position. If the view of the sky is clear, the signals of up to 12 satellites may be received at the same time. To determine a valid position, the data of at least three satellites is necessary. This works very well in open field. In this case, the accuracy is below 30 metres.

On a moving vehicle, accuracies of one metre and below can be achieved. Unfortunately, construction work is not always conducted in open space. In cities or in a built-up areas, various disturbances occur, shade for example. In this case, one or more satellites are likely to be blocked by high buildings. It is possible that the signals of only western, northern and southern satellites may be received, while all eastern satellites are blocked completely. This may be the case when standing very close to a building, for example.

Reflections are another cause of inaccuracy. The signals sent out by the GPS satellites are radio signals, which spread in wave form and can be reflected, by large metal surfaces (such as aeroplanes) for example. Due to these reflections the GPS module may not receive the signals directly, but after being reflected by another object or surface. The signal propagation delay may change, which may result in a greater divergence than normal (outlier). In a densely built area with high buildings, this may mean errors of tens of metres.

A car navigation system tries to offset the effects of these problems by assuming that the car is moving, and by checking that the position determined by the GPS module makes sense on the current road (a signal which indicates a sharp turn into a nearby field 100 metres before a junction is most likely an error, for example).

7.5.3 GPS ON / GPS OFF

Turn on the device by pressing the ‘START’ button. Then enter the ‘MAIN MENU’ by pressing the ‘SELECT’ button. Use the ‘SELECT’ button to move the arrow and select ‘GPS / TIME’ from the menu. Press the ‘START’ button (SET) to enter the ‘GPS / TIME’ menu.

To deactivate the GPS reception, position the arrow on ‘GPS IS ON’ and press the ‘START’ button (SET). ‘GPS IS OFF’ will then show on the display. If the GPS system is deactivated, the GPS icon will be absent from the ‘STATUS REQUEST’ screen.

If the GPS reception is switched off, and you would like to re-activate it, proceed as described above. After activating the GPS reception the GPS icon will appear during ‘STATUS REQUEST’. Press the ‘RESET/OFF’ button (EXIT) to return to the ‘MAIN MENU’. Press the ‘RESET/OFF’ button (EXIT) again to return to the ‘STATUS REQUEST’. The chosen GPS status will be shown either by the presence or by absence of the GPS icon, depending on whether you have chosen ‘GPS IS ON’ or ‘GPS IS OFF’. Pressing the ‘START’ button will start the test procedure.

8.3.7 Test Protocol of Individual Tests

The test protocol (for an example, see page 70) is divided into four areas:

Protocol heading, with general information about the test and the test instrument Test result chart, with the recorded test results and the required Evd value Settlement curves, with a presentation of the course of the three settlement curves, as well as a picture of

the testing point, if added Google®Maps satellite picture of the GPS coordinates (where these exist)

The following data will automatically be entered in the protocol heading for each individual test: device manufacturer, serial number, device type, data medium number, data record number, test date and time, GPS coordinates (if GPS is in use), and comments (where these have been entered via the text input function on the testing computer). Find out how to enter other project-specific data by referring to the chapter ‘Edit / Save Protocol’. This data cannot be altered / edited.

In the test result chart are listed the three recorded individual settlements in mm, the mean value of the three individual settlements in mm, the Evd value in MN/m2, the discrepancy between this and the required Evd value (entered manually beforehand), the s/v value in ms, and the required Ev2 value (entered manually beforehand). On the left hand side, below the test result chart, the three settlement curves are shown in different colours (s4= red, s5= green, s6= blue). From the shape of the settlement curves, the test duration, maximum settlement, and the course of the settlement can be deduced. If the ground has already been compacted, then the three settlement curves should be nearly congruent. On the right hand side of the test result chart, a picture of the testing point can be uploaded. The picture will be saved upon saving of the test data.

If GPS coordinates are available, and if a connection to the Internet exists, a Google®Maps display of the testing point will be added to the individual data record. It will feature the typical Google®Maps controls, and can thus be switched between satellite and map view, or zoomed in an out, for a better presentation.

A picture of the testing point can be added to every test protocol. It will be saved together with the test data.

The test data list on the left specifies all individual measurements loaded to the PC. A satellite picture of the testing point is displayed on the bottom right for the selected test. On the top right the individual data record with its three settlement curves is shown. In the space next to it, a picture of the testing point can be uploaded, if desired.

8.3.8 Test Data Loading

8.3.16 Select language

You can select the desired language of the software by double-clicking on the version number.

After double-clicking on the version number, the language selection will open.

8.3.17 Search Function for Individual Tests

The search function can be used only if the test data has previously been uploaded to the ‘TERRATEST

2.0’ program. Activate the search function by clicking on the ‘SEARCH’ button on top of the list which shows all uploaded tests. A search is possible only for the description fields ‘CONSTRUCTION PROJECT’, ‘COMMENTS’ and ‘GPS COORDINATES’. This function enables locating all tests that have been saved with the exact search term in these fields. For example, this function may be used to list all the tests which have been performed on a certain construction site.

The search can be refined by adding more filters. To do this, check the relevant box in front of the filter category and enter the search term in the description field behind the filter category. Up to three search terms can be combined with each other.

After clicking on the ‘SEARCH’ button the filter function will open.

As shown above, it is possible to switch the single search terms ‘COMMENTS’, ‘CONSTRUCTION PROJECT’, ‘GPS COORDINATES’ on and off by checking the respective boxes. If more than one search term is selected, only tests that match ALL search criteria will be listed. To activate the filter after entering the search words, click the button ‘ACTIVATE SEARCH’. All tests that match the search criteria will then be listed. To deactivate the filter, click the button ‘CANCEL SEARCH’.

The search function is deactivated (greyed out) while tests are marked for editing or added to the statistical analysis.

Keyword Search

If, instead of the list of all available tests, you want to see only those tests which contain a certain keyword in the ‘COMMENTS’ or ‘CONSTRUCTION PROJECT’ field, you can activate the relevant filter by checking the box in front of the filter name and entering the keyword in the filter description field. If you enter ‘MISSISSIPPI’ in the ‘CONSTRUCTION PROJECT’ field, test data for the construction project ‘MISSISSIPPI BRIDGE 2A’ and ‘DOT MISSISSIPPI’ will match the search criteria and will thus remain on the screen.

Searching for GPS Coordinates

Upon checking the search function ‘GPS COORDINATES’ the formula *° *,*N; *° *,*E will automatically be entered in the respective description field. This formula can be edited by entering the desired GPS coordinates. Only the placeholders * can be edited. The more numbers are entered, the more exact the search result will be. A number followed by a star refers to all values that start with the entered number. A star followed by a number refers to all values that end with the entered number.

Examples for the ‘GPS COORDINATES’ search:

5*° *,*N; *° *,*E (searches for all tests with 50°, 51°, 52°, ... up to 59° northern latitude) 52° *,*N; *° *,*E (searches for all tests with 52° northern latitude)

*5° *,*N; *° *,*E (searches for all tests with 5° northern latitude)

52° 27,2153N; 13° *,*E

(searches for all tests with exactly the specified N latitude and13° eastern longitude)

52° 27,21*N; 13° 23,30*E (a search accurate to two decimal places)

In this example, the test data will be filtered for all GPS coordinates placed on 52° northern latitude: 52°27,2107N;13°23,3080E, for example.

If searching for test data from a text location with coordinates in the western or southern hemisphere, replace the default ‘N’ for ‘S’ and the default ‘E’ for ‘W’.

Be aware that the GPS coordinates of the tests may show deviations for technical reasons. We therefore advice you to not enter exact eight/sixteen-number coordinates when using the ‘GPS COORDINATES’ search.

‘..... 3.4.7.2 Requirements for deflection modulus

The requirements detailed below are based on the 10% minimum quantile. When constructing roads corresponding to Construction Classes SV, or I to IV on frost-free subsoil or substructure, it is necessary to obtain a deflection modulus of at least Ev2= 120 MN/m2or alternatively Evd= 65 MN/m2on the subgrade. For Construction Classes V and VI a deflection modulus of at least Ev2= 100 MN/m2or alternatively

Evd= 50 MN/m2must be obtained. The deflection modulus Ev2is to be verified through the static plate load

test, as defined in DIN 18134, and the deflection modulus Evd through the dynamic plate load test, as defined in TP BF-StB Part B 8.3. If these requirements can be met only through compaction of the base courses, which are to be laid on the subgrade, it will be sufficient to prove or assess, by separate examination, a deflection modulus of at least Ev2= 100 MN/m2or alternatively Evd= 50 MN/m2on the subgrade for Construction Classes SV, or I to IV, and a deflection modulus of at least Ev2= 80 MN/m2or

alternatively Evd= 40 MN/m2on the subgrade for Construction Classes V and VI. If the subsoil or substructure is susceptible to frost, a deflection modulus of at least Ev2= 45 MN/m2or alternatively Evd= 25 MN/m2is necessary on the subgrade. For the scenarios outlined above, if the specifications of the

building contract do not state whether the static or dynamic deflection modulus is to be established, the static deflection modulus should always be used. Alternatively, one can perform a calibration according to TP BF-Stb Part E4, using the static deflection modulus to calibrate the dynamic deflection modulus. Afterwards, the dynamic deflection modulus may be used as a requirement. If the deflection modulus required on the subgrade cannot be achieved through compaction, it will be necessary to either

(1) improve or solidify the subsoil or substructure, or (2) increase the thickness of the unbound base courses.

The measures must be listed in the specifications of the building contract.

8.1 Conversion of Minimum Requirements

A minimum requirement for the deformation modulus Ev1 of the static plate load test can also be checked with the dynamic plate load test. The conversion of minimum requirements for the deformation modulus of the static plate load test (Ev1) to those for the dynamic deflection module of the dynamic plate load test (Evd) is carried out with the following formula for non-cohesive soils:

for Ev1≥ 25 MN/m2applies: Evd= 10 + 4–5E

for Ev1< 25 MN/m2applies: Evd= 6–5E

and for cohesive soils with the formula:

Evd= 10 + 4–5E

Chart 1 presents the relation.

Note:

Chart 1 helps you to convert requirements (limit values); however it should not be used to convert the test values (Evd-Ev1). The influence of the dynamic excess pore water pressure, which occurs with cohesive soils, the dispersion due to the high number of tests as well as the deviations caused by various tests under high rigidity have been considered during the creation of the chart.
