Bending Beam Rheometer

ASTM D6648 | AASHTO T313 | EN 14771 | NZTA M01-A: 2019
The Bending Beam Rheometer (BBR) test provides a measure of low temperature stiffness and relaxation properties of asphalt binders. These parameters give an indication of an asphalt binder’s ability to resist low temperature cracking.

81-PV5902: Bending Beam Rheometer (BBR) 230 V, 50-60 Hz, 1 ph

Main features:
  • Durable, corrosion-resistant construction
  • Computerized control, data acquisition and analysis
  • PID temperature controller with digital display
  • Two independent platinum RTDs for precise temperature control
  • Mechanically-refrigerated cooling bath with environmentally-safe non-CFC coolant
  • Integral LVDT and temperature compensated load cell for accurate test results
  • Includes complete calibration kit with carrying case
  • Includes ASTM/AASHTO-compliant specimen moulds
  • PC and software included

The Bending Beam Rheometer (BBR) is engineered to perform flexural tests on asphalt binder and similar specimens per ASTM D6648 and AASHTO T313. These tests consist of a constant force being applied to a specimen in a chilled bath in order to derive specific rates of deformation at various temperatures.

The Bending Beam Rheometer (BBR) System consists of a fluid bath base unit, a three-point bending test apparatus which is easily removed from the base unit for specimen loading and unloading, an external cooling unit with temperature controller, and a calibration hardware kit with carrying case. The system includes a PC and the testing software.

The Bending Beam Rheometer BBR can be used as part of your Superpave performance based testing program.
