Standard Test Method for Determining the Flexural Creep Stiffness of Asphalt Binder Using the Bending Beam Rheometer (BBR)
This test method covers the determination of the flexural creep stiffness or compliance and m-value of asphalt binders by means of a bending beam rheometer. It is applicable to material having stiffness values in the range of 20 MPa to 1 GPa and can be used with unaged material or with materials conditioned with procedures such as Test Method D2872 or Practice D6521. The test apparatus is designed for testing within the temperature range from –36 °C to 0 °C.
