AASHTO T 313-19 covers the determination of the flexural creep stiffness or compliance of asphalt binders by means of a bending beam rheometer. It is applicable to material having a flexural stiffness value from 20 MPa to 1 GPa (creep compliance values in the range of 50 nPa-1 to 1 nPa-1) and can be used with unaged material or with material aged using T240 (RTFOT) or R 28 (PAV), or both. The test apparatus is designed for testing within the temperature range from -36 to 0° C.
Test results are not valid for beams of asphalt binder that deflect more than 4mm, or less than 0.08 mm, when tested in accorance with this method.
