Scope
This test method covers the Binder Yield Energy Test (BYET) for evaluation of asphalt binders?? resistance to yield-type failure under monotonic constant shear-rate loading using the Dynamic Shear Rheometer (DSR). This test procedure can also be adapted for performing surrogate test procedure using the DSR in place of the conventional ductility test (T 51)@ and the Elastic Recovery test (ASTM D6084). The test method can be used with unaged material and material aged using T 240 (RTFOT) and/or R 28 (PAV) to simulate the estimated aging for in-service asphalt pavements. The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the safety problems@ if any@ associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
