Pavetest Bending Beam Rheometer
(
Asphalt
)
The Pavetest BBR is a thermoelectrically-cooled bending beam rheometer for testing flexural creep of asphalt binders from ambient to –40 °C (± 0.03 °C).
The load is applied by a miniature servo-controlled actuator capable of applying up to +/- 10N and loading frequency from static to 25Hz, without the need for compressed air supply. The use of servo-control eliminates the need for frequent calibration and repeated adjustment of air bearing pressures. Just enter the required load and the servo-controlled actuator will apply and maintain the requested load with incredible precision. The temperature is controlled very precisely using a temperature controller mounted on the front of the machine. The user can set the bath temperature using the controller or via the software. The heart of the system is Pavetest’s industry leading Control and Data Acquisition System (CDAS) and world acclaimed (TestLab) software.
Common Applications:
- Flexural creep of asphalt binders
- Low temperature characterization of crack seal under load
- ASTM D6648, AASHTO T313, SHRP Binder Provisions For Low Temperature Flexural Creep Testing of Asphalt Binders
