Model 2701-B 1–1

INTRODUCTION

Troxler, the leader in density gauge technology, now offers the
Model 2701-B PaveTracker Plus (see Figure 1–1), an
electromagnetic sensing device that quickly gives an indication of
the density of asphalt pavement. The advanced technology in the
patented PaveTracker Plus allows rapid and reliable measurements.
The PaveTracker Plus can be used on existing asphalt pavements or
on freshly placed mats. The unit is ideal for performing quick
quality control measurements to check for segregation, areas of low
density, and overall pavement uniformity.

The PaveTracker Plus is a precision device that is designed to
provide many years of trouble-free service. As any precision device,
the PaveTracker Plus requires reasonable care and maintenance to
ensure its accuracy and reliability. The user should:

♦ Keep the unit clean and free of all road debris.
♦ Return the unit to Troxler for yearly re-calibration and

inspection.

♦ Ensure that the unit remains sealed at all times. There are no

field-serviceable components inside the unit. Opening the case

will affect the integrity of the unit and therefore will void the
warranty.

FEATURES

The PaveTracker Plus (see Figure 1–1) incorporates a number of
features that provide unmatched efficiency, usability, and flexibility.

The PaveTracker Plus takes density measurements using
electromagnetic sensing technology, eliminating the need for
government licenses or special training. Measurements are
completed within 2 seconds, saving time and money.

The unit’s memory can store approximately 1000 readings for later
viewing, printing, or downloading.

Both the 30-button keypad and 4 x 20 liquid crystal display (LCD)
screen are backlit, making them easy to see, day or night.

The gauge includes a replaceable, protective, adhesive-backed
bottom cover disc on its bottom surface. The protective cover
provides thermal protection for the gauge’s internal components and
protects the bottom surface of the gauge against wear.

The carrying case for the Model 2701-B includes a built-in
reference standard, which provides a density measurement standard
for taking reference readings.

The PaveTracker Plus’s advanced software provides three test
modes (continuous, averaging, and segregation) for greater
flexibility and multiple applications. The software also provides
automatic calculations (average density, percent maximum density,
percent air voids, and so on) for greater ease of use.

The gauge allows the operator to specify the layer thickness; the
value entered is stored with other measurement data.

Gauge measurements can be adjusted using a density offset or mix
calibration (which includes slope and intercept values) to increase
accuracy on specific materials.

Both an ac charger and a dc adapter are included with the
PaveTracker Plus, enabling the unit to be recharged from an ac
outlet or a 12 V dc system.

1–4

The gauge features two audible indicators, an internally mounted
beeper, as well as a louder, external one mounted on its underside.
The internal beeper emits a short tone in response to a valid
keystroke on the keypad. It sounds a longer tone when the operator
presses an invalid key or if the gauge displays an error message. The
external beeper performs the same functions, and can be enabled or
disabled as desired by the operator.

A serial communications port is mounted on the front of the gauge.
The serial port is used to output data to a serial device, such as a
computer or printer.

The gauge features two handles. The right-angle handle is used to
move and position the gauge while taking measurements. A second
carrying handle is provided for ease of transporting and positioning
the gauge. An optional telescoping handle (PN 113017) is also
available.

2–4

The PaveTracker Plus features a backlit keypad and display. To
toggle the backlights on and off, press the 〈LIGHT〉 key.

NOTE

The keypad and display backlights increase the power
consumption of the unit. To conserve battery life,
Troxler recommends that the backlights be used only
when necessary.

To conserve power, the PaveTracker Plus provides a sleep mode, as
well as an automatic shutdown. If no key is pressed for five
minutes, the gauge enters sleep mode. In sleep mode, the display
and keypad backlights, and most of the electronics are turned off,
but all data and gauge settings are protected. To exit sleep mode,
press any key. If no key is pressed for 60 minutes, the gauge shuts
down automatically.

NOTE

If the gauge goes into sleep mode while in the continuous
measurement mode (see page 2–16), the display returns
to the Ready screen. In averaging or segregation mode,
the gauge maintains its current state when it enters sleep
mode.

The gauge software monitors the battery voltage. If the voltage falls
below 6.0 V dc, the gauge displays a low battery symbol (

) in the

upper right of the Ready screen. Recharge the batteries as
described on page A–4. After charging, the battery voltage should
be between 6.8 and 7.2 V dc. If the voltage falls below 5.5 V dc, the
gauge powers down automatically after completing any memory
store functions already in progress.

TARGET

The Model 2701-B can store up to four Gmb (Marshall) and four
Gmm (Voidless density) target values. A Gmb value is the bulk

density of a material, often determined using the Marshall method.
A Gmm value is the maximum theoretical density for a test material
as obtained in laboratory tests. The gauge uses target values to
determine the percent compaction and/or percent voids (if a Gmm
value is entered) as compared to the measured density of the test
material.

With the Target function, the operator can enter a new target value,
enable a stored target value, or disable a target value. To access the

MODE

The Model 2701-B provides three measurement modes:

♦ In continuous mode, the gauge takes a measurement and

updates the display every second. This mode is used for typical
quality control measurements.

♦ In averaging mode, the operator can take up to 30

measurements at selected locations. The gauge then calculates
the average of the measurements. This mode enables the
operator to determine the average density over a selected area.
The Store function (see page 5–10) records the most recent
results screen when in this mode.

♦ In segregation mode, the operator can take up to 30

measurements at selected locations. The gauge then displays the
high, low, and average density of the readings. This mode
enables the operator to determine the degree of segregation in
the area being measured. The Store function (see page 5–10)
records the most recent results screen when in this mode.

Before taking a measurement, select the appropriate measurement
mode. To select a measurement mode, press the 〈MODE〉 key. The
gauge displays:

-MODE-

1. Continuous

INTRODUCTION

As described on page 4–2, Troxler recommends taking a reference
reading each day that the gauge will be used, and periodically while
taking measurements. The reference reading consists of placing the
gauge on the reference standard contained in the gauge carrying
case and pressing the 〈Ref〉 key. The density read by the gauge is
then compared to the known density of the reference standard. The
result of this comparison is used to automatically adjust gauge
measurements.

For increased accuracy, measurements can be adjusted using density
offset and mix calibration values described in the following
sections.

To determine the density offset, take a gauge reading and compare
the measured value to an alternative density value, as measured by
another method (such as using a nuclear gauge or extraction and
analysis of a road core).

For a given material, the slope and intercept values can also be
determined using the Mix Calibration function (see page 3–6).

3–2

OFFSET

To improve the accuracy of the PaveTracker Plus for a specific
material of known density, the unit can be calibrated using a density
offset. A density offset is determined by taking in-place
measurements using the PaveTracker Plus, then comparing the
measured density to an alternative density, as determined using a
nuclear gauge reading or road core extraction and analysis.

DETERMINING THE DENSITY OFFSET

To determine the density offset for a given material:

1. Take a reference reading using the PaveTracker Plus as

described on page 4–2.

NOTE

Before using the PaveTracker Plus, inspect the
protective cover of the bottom surface of the gauge’s
sensor. Ensure that the cover is in good condition, and
has no deep scratches or buildup of material. If
necessary, replace the cover as described on page A–7.

2. Measure the in-place density of the material using the

PaveTracker Plus to find the measured density. Mark the test
site so that nuclear gauge readings or core extraction can be
conducted in the same location. If the core has already been
removed, take the measurement as close as possible to the core
location.

NOTE

When taking PaveTracker Plus measurement on a core
site, be sure to take measurements before the core is cut,
as the water used during the core cutting process may
affect PaveTracker Plus measurements.

3. Determine the alternative density of the material using a nuclear

gauge reading or road core extraction and analysis. Be sure to
conduct the gauge measurements or core extraction in the same
location as the PaveTracker Plus reading.

3. ADJUSTING MEASUREMENTS

Model 2701-B 3–3

4. Subtract the measured density from the alternative density to

determine the density offset to be entered into the PaveTracker
Plus software. For example, if the density as determined by a
core analysis is 150 pcf, and the density measured by
PaveTracker Plus is 146 pcf, the density offset is +4 pcf.

NOTE

For best results, repeat the above procedure to
determine the density offset at each of several in-place
locations. Then calculate the average density offset.

MANAGING DENSITY OFFSETS

Density offsets are managed using the Density Offset menu. To
access this menu, press 〈OFFSET〉. The gauge displays:

Density Offset
#.## pcf
1-Enable 2-Disable
3-Change Offset

The gauge displays the current density offset on the second line. To
enable the offset, press 〈1〉. To disable the offset, press 〈2〉.

To enter a new density offset, press 〈3〉. The gauge prompts for the
density offset as shown below:

Press <ENTER>

Enter the density offset as determined from the procedure on page
3–3 and press 〈ENTER/START〉. The gauge enables the new offset
and returns to the Ready screen.

Model 2701-B 3–5

MIX CALIBRATION

As noted earlier, the PaveTracker Plus can be calibrated for a
specific mix using the Mix Calibration function. To use this
function, the operator takes gauge measurements at three to ten
locations across the material. The gauge compares these values to
values obtained by core analysis or another method to determine a
slope and intercept for that particular material. The gauge can store
up to four mix calibrations.

NOTE

In order for the gauge to calculate both a slope and an
intercept for the test material, measurements must be
performed at a minimum of three locations. Also, the
difference between the minimum and maximum reading
must be at least 3 pcf. For best results, Troxler
recommends taking measurements at seven to ten
locations.

To access the Mix Calibration function, press 〈7〉 on the Setup
menu shown on page 2–7. The gauge displays:

Model 2701-B 4–1

TAKING A REFERENCE READING

To ensure the accuracy of gauge measurements, Troxler
recommends that a reference reading be taken each time the gauge
is powered on, and periodically while taking measurements. A
reference reading consists of taking a density measurement on a
material of known density. The gauge then compares the reading to
the known value and uses the result of that comparison to adjust
future gauge readings.

NOTE

A reference standard, built into the gauge carrying case,
is provided for this purpose. Always take reference
readings using the reference standard in the carrying
case provided with the specific unit.

Turn the gauge on as described on page 2–4. At the Ready screen,
press the 〈REF〉 key. The gauge displays:

Place Gauge on
Reference Standard
(Carrying Case)
Press <START>

Place the gauge on the reference standard (in the carrying case).
Ensure that the circular sensor on the bottom of the gauge is
centered between the four locating pins inside the case, and that the
sensor rests flat against the surface.

Press the 〈ENTER/START〉 key to begin the reference reading.
Upon completion, the gauge displays:

Reference Reading
Complete

Press <ENTER>

Press the 〈ENTER/START〉 key to continue. The gauge stores the
result of the reading and returns to the Ready screen. The result is
then used to adjust all gauge readings.

4–2

NOTE

If the reference reading is out of range and the gauge
displays an error message, check the following:

♦ Ensure that the circular sensor cover is firmly in

place on the gauge sensor (press firmly around the
perimeter of the cover).

♦ Ensure that the cover and reference standard are

totally clean and free of any asphalt residue,
moisture, or debris. Clean with WD-40 or other
suitable means.

♦ Ensure that the sensor cover is seated flat and flush

on the reference standard, within the four locating
pins, with the gauge in the case.

Repeat the reference reading. If the reference reading
still does not pass, contact Troxler technical support (see
page A–10).

To verify that the gauge is still accurate during use,
perform the following check:

♦ Ensure that the gauge is turned on and in

measurement mode.

♦ Turn off (disable) all operator-installed density

offsets and mix calibrations. See Chapter 3 for
specifics.

♦ Place the gauge on the reference standard and verify

that it reads within ± 0.5 pcf (±8 kg/m

3

) of the actual
density value stamped on the reference standard. If
the reading is outside these limits, take a reference
reading as described in this section to adjust the

4. USING THE GAUGE

gauge.

Note that each reference standard is unique to that
individual gauge. Use care to not intermix different
gauges and cases.

Model 2701-B 4–3

PREPARING A TEST SITE

To ensure measurement accuracy, properly prepare the test site
before taking gauge measurements.

 Locate a smooth site on the asphalt.
 To ensure accurate readings, the gauge sensor must be

completely in contact with the test material. If the gauge rocks,
then find a more suitable test site. If taking a measurement
around a core, the gauge may be moved a few inches away from
the core to level it.

4–4

TAKING MEASUREMENTS

The Status feature (see page 2–6) allows the operator to view the
current gauge status. This feature provides a quick overview of the
battery voltage, internal temperature, selected measurement units,
and the date and time of the last reference reading. If necessary,
check the gauge’s current status before taking measurements.

NOTE

To ensure the accuracy of gauge measurements, take a
reference reading each day the gauge is to be used (see
page 4–2) and periodically while taking measurements.

As described on page 2–16, the PaveTracker Plus provides three
measurement modes: continuous, averaging, and segregation.
Before taking a measurement, select the appropriate measurement
mode.

CAUTION

High internal temperatures may damage the gauge’s
electronic components. To reduce the risk of damage,
DO NOT allow the gauge to sit on hot asphalt for
extended periods.

If the internal temperature of the gauge reaches a level
that is considered excessive, the beeper will sound and
the warning message Internal temp. high Allow
gauge to cool will be displayed. The gauge should be
taken to a shady or air-conditioned environment and
allowed to cool before continuing. If measurements are
performed before the gauge is allowed to cool, the
warning symbol ! is displayed.

4. USING THE GAUGE

CAUTION

The gauge includes a replaceable protective cover that
protects the bottom surface of the gauge’s sensor
assembly against wear and provides thermal protection
for the gauge’s internal components. To prevent damage
to the gauge, DO NOT operate the gauge without the
protective cover.

Model 2701-B 4–5

NOTE

Before using the gauge, inspect the protective cover of
the bottom surface of the gauge’s sensor. Ensure that
the cover is in good condition, and has no deep scratches
or buildup of material. If necessary, replace the cover as
described on page A–7.

CONTINUOUS MODE

In continuous mode, the gauge takes a measurement and updates the
display every second. This mode is used for typical quality control
measurements.

Extend the telescoping handle (see Figure 1–1) to reduce the
bending required while taking measurements.

To take a measurement in continuous mode, select the mode as
described on page 2–16. Place the gauge on the test site and press
〈ENTER/START〉.

The gauge displays the measurement results, updated every second,
as shown:

##.#% Gmb(MA)
##.#% Gmm(Voidless)
D: ###.#
##.#% Voids <ESC>

NOTE

NOTE

If the gauge goes into sleep mode while in the continuous
measurement mode (see page 2–16), the display returns
to the Ready screen. To exit sleep mode and continue
taking measurements, press the 〈ENTER/START〉 key.

AVERAGING MODE

In averaging mode, the operator can take up to 30 measurements at
selected locations. The gauge then calculates the average of the
measurements. This mode enables the operator to determine the
average density over a larger area.

Extend the telescoping handle (see Figure 1–1) to reduce the
bending required while taking measurements.

To take a measurement in averaging mode, select the mode as
described on page 2–16.

TROUBLESHOOTING

GAUGE WILL NOT COMMUNICATE WITH PRINTER OR
COMPUTER

 Check that the correct cable is being used.
 Ensure that the printer/computer baud rate is 9,600 bps.
 Ensure that all other parameters match:

♦ Data bits = 8
♦ Stop bits = 2
♦ Parity = none
♦ Protocol = DSR/DTR

GAUGE TURNS OFF AFTER IT IS TURNED ON

 To conserve power, the gauge provides an automatic shutdown

if no key is pressed for 60 minutes. To turn the gauge on, press
the power switch.

 If the rechargeable NiMH battery pack is below 5.5 V dc, the

gauge shuts down. Recharge or replace the batteries (see page
A–4).

SHORT BATTERY LIFE AFTER RECHARGING

 NiMH batteries may be charged up to 500 or more full

charge/discharge cycles, and typically have a 4-year life. The
batteries may be reaching the end of their life cycle, and should
be replaced.

 Charger/adapter may not be supplying full charge – check the ac

outlet and the dc output (12 V dc) using a voltmeter on the
proper setting.

 Check that you are using the correct charger.
 The ac charger may be defective. To check, use the dc adapter

to charge the batteries.

Appendix A–2

A

INTERNAL GAUGE TEMPERATURE

High internal temperatures may damage the gauge’s electronic
components. To reduce the risk of damage, DO NOT allow the

gauge to sit on hot asphalt for extended periods.

If the internal temperature of the gauge reaches a level that is
considered excessive, the beeper will sound and the following
warning message is displayed:

Internal temp. high
Allow gauge to cool
Press Enter to
resume

The gauge should be taken to a shaded or air-conditioned
environment and allowed to cool before continuing. If
measurements are performed before the gauge is allowed to cool,
the warning symbol ! is displayed.

. TROUBLESHOOTING

Model 2701-B Appendix A–3

BATTERIES

The PaveTracker Plus is equipped with one set of rechargeable
nickel-metal hydride (NiMH) batteries (pack of five C batteries).
The gauge software monitors the NiMH battery voltage. When the
batteries are fully charged, the battery voltage should be between

6.8 and 7.2 V dc. If the voltage falls below 6.0 V dc, the gauge
displays a low battery symbol (
screen. Recharge the batteries as described below.

If the voltage falls below 5.5 V dc, the gauge powers down
automatically after completing any memory store functions already
in progress. Troxler recommends that the operator recharge the
NiMH batteries. The NiMH batteries can be fully recharged in only

2.5 hours.

CHARGING

To charge the NiMH batteries, plug the charger into the round jack
on the front of the gauge. Plug the other end of the ac charger into a
standard 100–240 V ac outlet.

The dc adapter may be connected to any 12-14 V dc source (such as
a vehicle's cigarette lighter). To ensure a full charge, charge the
batteries for at least 2.5 hours. After charging, the battery voltage
should be between 6.8 and 7.2 V dc.

After recharging the batteries, unplug the charger from both the wall
outlet and the gauge. Store the charger for later use.

) in the upper right of the Ready

Appendix A–4

A

REPLACING THE BATTERIES

To replace the NiMH battery pack (PN 110374):

 Turn the gauge off.
 Using a 1/8-inch Allen wrench, remove the two screws that

secure the battery cover to the base of the unit.

 Clean the screws and set them aside.
 Carefully lift the old NiMH battery pack from the gauge.
 Unplug the battery cable from the battery connection on the top

circuit board. Gently squeeze the connector to disconnect.

 Plug the battery cable for the new NiMH battery pack into the

battery connection on the top circuit board.

 Slide the battery pack into the gauge.
 Replace the battery cover and replace the two screws.

. TROUBLESHOOTING

Model 2701-B Appendix A–5

CLEANING THE BASE AND TOP SHELL

To clean the gauge base, use a putty knife to scrape away any built­up accumulations of soil or asphalt. Be careful not to scrape or

scratch the round sensor, as damage to the sensor may cause
erroneous readings. Also be careful not to damage the gauge
base.

After removing any large accumulations, wipe the gauge base with a
cloth soaked in an adhesive remover (such as Goo Gone®), then
wipe with alcohol to remove the remaining debris.

The keypad may be cleaned using a mild soap (such as 409™ or
Fantastic™), followed by clean water.

The Model 2701-B gauge top shell is manufactured from an
engineering thermoplastic designed specifically to provide high
impact strength and to offer excellent compatibility with many
industrial solvents and petro-chemicals. The top shell may be
cleaned with mild (low alkaline) soap and water. Other approved
cleaning substances include: methyl, isopropyl, or isobutyl alcohols.
A cloth dampened with kerosene or diesel fuel may be used to
remove heavy soils. Avoid prolonged exposure and do not soak.

CAUTION

The use of any unapproved cleaning agents such as
methyl-ethyl-ketones, amines, and methylene chloride
will damage the top shell and void the warranty.

Appendix A–6

A

REPLACING THE PROTECTIVE COVER

The gauge includes a replaceable, adhesive-backed bottom cover
disc that protects the bottom surface of the gauge’s sensor assembly
against wear and provides thermal protection for the gauge’s
internal components. The protective cover disc adheres to the rear
base assembly. When the disc becomes worn, it should be replaced
as described below.

CAUTION

To prevent damage to the gauge, DO NOT operate the
gauge without the protective cover disc.

NOTE

Additional bottom cover discs can be purchased from
Troxler by ordering PN 113103, Cover Replacement Kit,
which includes three discs.

To remove the old protective cover disc:
 Turn the gauge over so that its bottom surface is exposed. To

prevent damage to the keypad or display, place the gauge on a
soft surface.

. TROUBLESHOOTING

 Using a knife or other flat object, gently lift the edge of the disc.

After loosening, peel the cover off by hand.

To install the replacement protective cover disc:
 Clean the surface of the sensor with alcohol (used sparingly)

and allow the surface to dry.

 Peel the adhesive backing from the replacement protective

cover disc.

 Align the replacement cover disc with the sensor and press it

into place. Smooth out the disc to eliminate air bubbles.

NOTE

Do not remove and re-install the same cover disc, as the
adhesive will be weakened.
