AASHTO T 391-20 Standard Method of Test for Estimating Fatigue Resistance of Asphalt Binders Using the Linear Amplitude Sweep, Single User PDF Download
standard by American Association of State and Highway Transportation Officials, 2020
Full Description
AASHTO T 391-20 covers the determination of an asphalt binders 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.
