This test method 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?C1 to 1 nPa?C1) and can be used with unaged material or with material aged using T 240 (RTFOT) or R 28 (PAV)@ or both. The test apparatus is designed for testing within the temperature range from ?C36 to 0?? Test results are not valid for beams of asphalt binder that deflect more than 4 mm@ or less than 0.08 mm@ when tested in accordance with this method. 1.3. This standard may involve hazardous materials@ operations@ and equipment. This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this procedure to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
