This test method covers the determination of the flexural creep stiffness or compliance of asphalt mixtures by means of a bending beam rheometer. It is applicable to material having a flexural stiffness value from 2 GPa to 20 GPa (creep compliance values in the range of 0.5 nPa–1 to 0.05 nPa–1). The test apparatus is designed for testing within the temperature range from –36 to 0°C.
Test results are valid for beams of asphalt mixtures that deflect at least 15 μm and less than 150 μm (550 microstrains) during the entire duration of the test, when tested in accordance with this method.
This method has been verified with asphalt mixtures having a nominal maximum aggregate size of 12.5 mm.
