- EN 14771
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 BBR is supplied complete with a suitable chiller to ensure a temperature range between ambient and -40°C. 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
