Durable, High-Quality System for Determination of Flexural Creep Stiffness of Asphalt Binder
The ATS Bending Beam Rheometer (BBR) has been engineered to perform flexural tests on asphalt binder and similar specimens per ASTM D6648-01 and AASHTO T313-02. These tests, initially developed by the Strategic Highway Research Program (SHRP), consist of a constant force being applied to a specimen in a chilled fluid bath in order to derive specific rates of deformation at various temperatures.
A complete BBR system consists of a fluid bath base unit, a three-point bend 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.
Additionally, the BBR has recently been redesigned according to the latest revisions of the relevant ASTM and AASHTO specifications. This new design includes updated and improved software as well as features that make the BBR safer, easier, and more accurate.
