GENERAL DESCRIPTION

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.

                         

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.
