Chapter 1:
Introducing the Asphalt Submersion Cell
Overview
The TA Instruments Asphalt Submersion Cell is a Smart Swap™ accessory designed to be used with the
DHR Series and AR Series Rheometers. For the general operation of those instruments, including use of
the Smart Swap system, see the appropriate operator's manual.
The Submersion Cell is specifically designed to satisfy the latest Federal Highway Administration
(FHWA) requirements for asphalt binder testing. When used with the cell, the DHR Series and AR Series
Rheometers meet the requirements of Dynamic Shear Rheometer (DSR) as defined by the FHWA.
The cell is designed to be used with a Julabo Computer Controlled Fluid Circulator (CCFC), normally
model FP35-HE. The operation of the cell and CCFC is directly controlled through TRIOS Software. For
full details of the operation of the Julabo and Safety information, see the manufacturers operating manual.
A summary is provided in Appendix A of this manual.
Historically, asphalt characterization was based on measurements of penetration, capillary viscosity and
ductility. While these measurements were repeatable, they could not be easily correlated to end-use perfor-
mance characteristics such as rutting or cracking. Recently an exhaustive multiyear study (SHRP) by
FHWA resulted in the adoption of alternative measurements that solve this correlation problem. These new
measurements provide a set of alternative criteria for selecting asphalt binders and aggregate mixes to meet
specific end-use conditions.
Techniques Used
For asphalt binders, the new measurements are based on the Bending Beam Rheometer, the Direct Tension
Tester, and the Dynamic Shear Rheometer (DSR). The first two techniques evaluate low temperature per-
formance, whereas the DSR evaluates performance over a broader temperature range (5 to 85°C).
Specifically, the DSR test measurements include:
• AASHTO T315 & ASTM D7175: Determining the Rheological Properties of Asphalt Binder Using a
Dynamic Shear Rheometer (DSR).
• AASHTO R29 & M320: Grading or Verifying the Performance Grade of an Asphalt Binder.
• AASHTO TP70 & ASTM D7405: Multiple Stress Creep and Recovery (MSCR) of Asphalt Binder
Using a Dynamic Shear Rheometer
• AASHTO XXXX: High stress repeated creep
• AASHTO XXXX: Determining the mixing and compaction temperature of asphalt binder
This manual should be read in conjunction with these Standard Methods. The cell can be used with TRIOS
Software, but for full automated testing using the standards listed above, Rheology Navigator and
Rheology Advantage are required. More information about the operation of this software can be found in
CSA II Asphalt Rheometerwith Rheology Navigator Software PDF.

Routine Maintenance
It is recommended that the following procedures be carried out on a regular basis:
•Circulation fluid: This should be changed once per week, or if the water becomes contaminated.
•Inline water filter: The filter should be removed, and cleaned or replaced, when visibly contaminated.
See the next section for details.
•Asphalt Temperature Control Cell filters: These should be changed when visibly contaminated. See
the next section for details
•TheFlow Deflector Turret, shown below, should be unscrewed and cleaned.
Figure 6 Flow Deflector Turret.
Filters and Plates
Before the Asphalt Submersion Cell is used, you will need to perform several functions:
• Check the drain and inline filters on the cell. The filters should be clean and free of debris.
aTo replace the lower drain filter, which is a 6-mm single hole punched from the filter sheet, use
tweezers to place the filter in the drain. Then secure the filter with a quarter turn.
bTo replace the inline filter, disassemble the filter-housing unit and remove the tubing. Cut a filter
from the sheet provided—it should be approximately 25 mm long and 10 mm wide. Then use a pair
of tweezers to replace the filter.
CAUTION: Do not pack the filter material too tightly as this may result in an overflow situation.
MISE EN GARDE: Ne serrez pas trop l'emballage du matériel du filtre car cela risque de provoquer
un débordement.
• Clean the plates used in the cell regularly. To remove or install the plates, see the next section. The
plates are manufactured from stainless steel so they can be cleaned in a solvent bath.

Chapter 4:
Troubleshooting
Solving Common Asphalt Submersion Cell Problems
This chapter provides answers to some common problems that can occur while using the Asphalt Submer-
sion Cell. If you cannot solve the problem using one of the suggestions on the following pages, contact
your TA Instruments Service Representative for assistance.
Flow Problems
The flow in and out of the temperature control cell is balanced by the size of the tubing and the efficiency
of the pump and suction. The temperature control parameters are optimized for this flow rate. Temperature
stability is generally related to flow rates. The on/off valve should not be used to reduce the flow rate, other
than during sample loading, if splashing of the lower plate is a problem.
Temperature Control Cell Overflows
This is caused by inefficiency in the suction side of the system. If you use the on/off valve to reduce the
flow rate and stop the overflow, poor temperature control is likely to result.
Try to isolate the problem area. Check the following:
• Remove all filter material.
• Disconnect and reconnect all pipes.
• Consider replacing pipes if they are visibly contaminated.
• Remove and clean solenoid valve located behind column back panel. Replace the valve, if it appears
worn. Turn off power to the instrument before removing the back panel.
Poor Temperature Control
Try the following solutions to poor temperature control:
• Make sure that the on/off valve is fully open.
• Make sure that the configuration parameters in the CCFC have not been tampered with.
• Remove the flow deflection turret and check for blockages.
• Disconnect the pipe from the inlet to the cell and measure the flow rate at the height of the cell. If the
flow rate is less than 450ml/min try replacing the pipe, or flush the CCFC with solvent.

DHR/AR Series Asphalt Submersion Cell Getting Started Guide Page 18
Leaks
If you find leaks occurring, first locate the pipe that is leaking. Turn off the fluid circulator’s main power
switch before disconnecting any lines. Disconnect and reconnect the problem pipe. If problem persists, use
a sharp straight tool to trim approximately 3 mm from the end of the pipe (do not use scissors, as this will
pinch a hose flat). Then reconnect the pipe.
