IInnttrroodduuccttiioonn ttoo tthhee AADDUU

The Automatic Drying Unit is a fully-automated device that
dries specimens placed in the chamber. It is intended for use
with compacted asphalt core samples as well as loose asphalt
mix and loose aggregate (with supplied sample bag). In
comparison to the current methods used for drying these
samples, the ADU is very fast and convenient.

Currently, compacted asphalt cores are allowed to dry in front
of a fan for several hours. The cores are weighed, then dried
further and weighed again to be sure that they are truly dry.
These cores cannot typically be analyzed for density until the
day following their removal from the pavement. The ADU fully
automates and significantly shortens this process, allowing
the laboratory technician to be free to complete other tasks.

The ADU uses a simple process of vacuuming the air from the
sample chamber, thus pulling the water from the sample. A
heating element is placed outside the chamber to allow the
sample to remain close to ambient temperature. The water
that is evacuated from the chamber is transferred to a
reservoir and trapped there so that the pump is protected
from damage.

The pump draws the air and water from the sample and
chamber until the pressure reaches a level predetermined as a
“dry calibration” value. At this point the sample is considered
dry and the process is complete. The sample can then be
further analyzed for the properties that need to be
determined.

Compacted Asphalt Core Samples

11.

.

To dry a typical 100 mm or 150 mm (4 in. or 6 in.)

compacted asphalt core sample, the ADU must be set to
Core mode under the Profile menu, located in the Setup
menu (see page 3-4).

22.

.

Acquire core specimens in accordance with ASTM D5361.

33.

.

Place the core(s) in the sample chamber resting on the

sample tray. The sample(s) should not make contact with
the sides of the chamber. If multiple samples are dried
together, the samples should not be in contact with each
other.

44.

.

Once the sample(s) are in the chamber, place the lid

securely on the top of the chamber. It is important that
the lid gasket make good contact with the chamber in
order to seal tightly.

55.

.

Press ENTER to begin the measurement.

66.

.

The following screen will display:

Troxler ADU 5151

.

The ADU then begins a series of vacuum cycles during

which it removes the moisture from the sample(s). At the
same time, the heating unit is warming the chamber to
ensure that the sample remains near room temperature.

2-6

88.

.

The number of cycles is determined by how long it takes

to get to a predetermined “dry calibration” value. Larger
samples and samples with more void space will generally
take longer, as will extremely wet samples.

99.

.

If the number of cycles reaches 20 before the “dry

calibration” value is reached, the ADU will stop and give a
message to rotate the sample, replace the lid, and press
ENTER. After the vacuum begins again, the sample(s) will
dry quickly.

Please turn sample over
to continue drying.
Press <ENTER>

Model 5151 2-7

NOTE

The Pressure Check automatically adjusts the ADU
for changes in atmospheric pressure. If a significant
change in atmospheric pressure occurs during the
course of a workday, perform a new Pressure Check.

Loose Asphalt Mix or Aggregate Samples

The ADU can also be used to dry loose aggregate or asphalt
mix. Before performing this procedure, change the Profile to
Aggregate mode in the Setup menu (see page 3-4).

To calculate the moisture content of loose aggregate, follow
the typical procedure used when drying the sample in an
oven. Simply weigh the sample before drying, place sample in
the ADU, and run through a cycle. Weigh the material after
the cycle and calculate the percent moisture that was
contained in the sample.

The process for drying loose samples is very similar to drying
a compacted core sample. Follow the instructions below for
drying loose mix and aggregate.

11.

.

Place the loose sample inside the aggregate bag provided

with the unit. Always ensure the bag is properly secured
before drying. Failure to do so could damage the ADU and
void any remaining warranty.

22.

.

Place the bag in the sample chamber and rest it on the

sample tray. The bag should not make contact with the
sides of the chamber.

33.

.

Place the lid securely on the chamber. It is important that

the lid gasket make good contact with the chamber in
order to seal properly.

2-8

44.

.

Press ENTER to begin the measurement.

55.

.

If the number of cycles reaches 10 before the “dry

calibration” is reached, the ADU will stop and give a
message to turn the sample over. Remove the bag from
the chamber and gently shake it. Turn the bag over and
place back into the chamber. Replace the lid and press
ENTER to complete the drying.

Extremely Wet Samples

If the sample has completed 40 cycles and is not completely
dry, remove the sample from the chamber to prevent
overheating.

11.

.

Hold down the ESC key to stop the drying cycle.

22.

.

Remove the sample and allow it to cool at room

temperature for at least 30 minutes.

33.

.

After the sample has cooled, place it back into the

chamber to finish drying.

Moisture Reservoir

After a sample is dried, water will collect in the moisture
reservoir. It is recommended that this be dried after a very wet
sample or after two to four typical samples dried in the ADU.

If too much moisture is allowed to accumulate in the reservoir,
the moisture may be drawn into the pump, shortening the
pump life.
