The improved ATS Bending Beam Rheometer (BBR2S) is engineered to perform flexural tests on asphalt binder/bitumen and similar specimens per ASTM D6648, BS EN 14771, 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. Enhanced software and the ability to perform crack sealant tests expand the capabilities of the BBR2S beyond those of the original BBR2. Intuitive programming guides operators through test setup, providing a highly customizable and user-friendly experience.
