AASHTO T 313-19 Download


Standard Method of Test for Determining the Flexural Creep Stiffness of Asphalt Binder Using the Bending Beam Rheometer (BBR)
standard by American Association of State and Highway Transportation Officials, 2019



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.
