This practice provides a means of evaluating the behavior of an asphalt binder at low temperature using the results (Stiffness and m-value) from the Bending Beam Rheometer (BBR) test to calculate a value (identified as Delta Tc or ΔTc) that is indicative of the relaxation properties of the asphalt binder. This practice is primarily intended for use with residue generated after long-term conditioning with T 240 (Rolling Thin-Film Oven (RTFO)) and R 28 (Pressurized Aging Vessel (PAV)), but may also be used on recovered asphalt binder from asphalt mixture, reclaimed asphalt pavement (RAP), and reclaimed asphalt shingles (RAS) ...
