Introduction This manual describes the CANNON Thermoelectric Bending Beam Rheometer and the procedures for obtaining test data. The Bending Beam Rheometer is used to make rapid determinations of the flexural-creep stiffness of asphalt binders over a temperature range of 0 °C to -36 °C. -
Page 13: Control Unit
The pressure in the air chamber, or cylinder, can be adjusted - any desired load can be applied to the specimen, up to the maximum or the full weight of the shaft. Refer to Figure 3. TE-BBR Instruction and Operation Manual... -
Page 14: Manual Operation
The Air/Water Heat Exchanger consists of a radiator, fan(s), and a water pump to circulate and cool a mixture of water and ethylene glycol flowing through the hot side heat sinks surrounding the bath in the Control Unit. Circulation of the mixture removes heat from the Control Unit bath. CANNON Instrument Company | Introduction... -

Exchanger/Refrigeration Place the Refrigeration Unit (BBR model) or Air/Water Heat Exchanger (TE-BBR model) on the floor below the Control Unit. Do not place the unit on the same table as the Control Unit as the fan/motor vibration can interfere with the sensitive measuring system of the Load Unit. Also, it is necessary to provide 15 cm (6") of clearance on all sides of the unit for sufficient air circulation. -

6.35 mm (¼") thick stainless steel beam and four 100 gram weights are supplied for the calibration. At the end of the calibration run, remove the weights from the load platform, and the 6.35 mm (¼") steel beam from the bath. TE-BBR Instruction and Operation Manual... -
Page 38: Compliance
A thin (approximately 1.20 mm) steel beam is needed, as well as two to four 100-gram weights, depending on the laboratory calibration protocol. If the test fails repeatedly, recalibrate the instrument and rerun the confidence test. CANNON Instrument Company | Calibration... -
Page 39: Verify Calibration
10. Add one 2-gram weight (± 0.2 g) to the load platform. 11. Verify that the force increases by 20 mN ± TOL. 12. Add a second 2-gram weight (± 0.2 g) to the load platform. TE-BBR Instruction and Operation Manual... -

• Specimen demolding When preparing the specimen, make sure to allow time for the TE-BBR bath to reach the test temperature and stabilize. The bath should be equilibrated at the test temperature for at least 30 minutes before running the asphalt beam test. - Page 46 To prevent asphalt from sticking to these surfaces, cover them with a thin layer of debonding agent (CANNON recommends using a mixture of talcum powder and glycerol) and a narrow spatula, wire or rod. Avoid spreading the mixture on the plastic surfaces.

Page 49: Specimen Demolding
Caution: Use caution when cooling the specimen as asphalt may be brittle at lower temperatures. Do not use the TE-BBR test bath to cool the sample. Immersing the warm mold in the bath could disturb the temperature equilibration and force a delay in testing. - Page 50 Note: The demolding operation should be done as quickly as possible to prevent deformation of the specimen.

Flush Procedure 1. Turn off the TE-BBR power switch to remove power from the instrument and Exchanger. 2. Detach the quick-connect fitting securing the tubing from the BBR to the IN connection on the Exchanger by pushing down on the release button while pulling the hose connection out. Refer to Figure 14. -
Page 58: Drain Fluid Procedure
After the antifreeze mixture has been flushed from the Air/Water Heat Exchanger per the preceding procedure, drain the system as follows: 1. Make certain that the TE-BBR power is OFF. Remove the external housing from the Air/Water Heat Exchanger by removing the six screws securing the housing to the sides of the frame (three screws on each side of the unit) and the six screws on the top and sides of the rear panel. -

Record the voltage as NO LOAD voltage. Add a 100-gram weight to the Load Platform. k. Record the voltage as the 100-GRAM voltage. Call the Service department at Cannon Instrument Company and report the voltage levels obtained with this diagnostic. Temperature Reading Error Problem: The temperature reading displayed on the computer appears incorrectly. -
Page 63: Internal Wiring
5. Rerun the confidence test. Level the BBR If the TE-BBR is not level, the weight platform may rub against the steel bar used to prevent rotation of the platform. The resulting friction produces an erroneous measure of the steel beam modulus. -
Page 64: Incorrect Load Values
Test the TE-BBR for correct voltage readings for Force: 1. Locate the TE-BBR test cable with the phono plug on one end and two alligator clips at the other end (cable is shipped with the instrument). -
Page 65: Fluctuation In Deflection/Load During A Test
Several tests can be performed to isolate an electrical problem. Check the TE-BBR Voltage Values for Force and Deflection 1. Locate the TE-BBR test cable with the phono plug on one end and two alligator clips at the other end (cable is shipped with the instrument). -
Page 66: Clean The Instrument Housing
Turn off all power and unplug the power cord before cleaning the BBR. Periodically clean the outside of the TE-BBR units with a damp cloth moistened with water and/or a mild detergent solution. Do not wipe or otherwise apply pressure to the base of the load shaft in order to avoid damaging the load cell. -
Page 67: Adjusting Bending Beam Rheometer Force And Deflection Voltages
Adjusting Bending Beam Rheometer Force and Deflection Voltages This section provides notes on adjusting the force and deflection voltages for the TE-BBR Bending Beam Rheometer. To complete the force adjustment procedure, the VR5 POT (VR2 POT on the old version) and the VR3 POT must be changed to match the desired voltage. -

Page 71: Check Function Of Te-Bbr Cooling Modules
This technical note provides a preliminary procedure for checking function of the thermoelectric cooling modules mounted internally to the TE-BBR bath. The procedure will check the integrity of the electrical circuit defined by input and output leads from the modules. -
Page 72: Check The Thermostat
7. Set the multimeter to indicate resistance (ohms). 8. Check the multimeter reading. It should indicate a completed circuit (zero to very low ohm value). If it does not, then the function of the modules has been compromised, and the TE-BBR unit needs to be repaired. -
Page 73: Clean Air Bearing Shaft And Load Cylinder In Te-Bbr
Follow the procedure outlined in this section to remove contaminants that were introduced through the twin air lines to the load cylinder. 1. Turn off instrument power at the rear of the TE-BBR Control Unit. Remove the Load Frame from the bath and place it on top of the Control Unit. -
Page 74: Figure 29: Load Cylinder Air Line Connections
5. Using a wrench, disconnect the upper and lower air line at the load cylinder. 6. Restore power to the TE-BBR and permit air to blow through the unattached air lines for two or three minutes to clear the lines of any contaminants. - Page 75 15. If travel is restored, use the previously removed screws to replace the Load Frame front cover, replace the Load Frame in the bath, and continue with normal TE-BBR operations. If the cleaning procedures have failed, contact CANNON Instrument Company for further assistance.
