Standard Method of Test for Estimating Fatigue Resistance of Asphalt Binders Using the Linear Amplitude Sweep
AASHTO T 391
Year: 2020
Abstract: This test method covers the determination of an asphalt binder’s resistance to fatigue damage by means of cyclic loading employing systematic, linearly increasing load amplitudes.
The amplitude sweep is conducted using the Dynamic Shear Rheometer (DSR) at the intermediate pavement temperature determined from the performance grade (PG) of the asphalt binder according to M 320.
The test method can be used with binder aged using T 240 (RTFOT) and R 28 (PAV) to simulate the 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 concerns, 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.
