ASTM D113-17

1.1 This test method describes the procedure for determining the ductility of an asphalt material measured by the distance to which it will elongate before breaking when two ends of a briquet specimen of the material, of the form described in 4.1, are pulled apart at a specified speed and at a specified temperature. Unless otherwise specified, the test shall be made at a temperature of 25 ± 0.5 °C [77 ± 0.9 °F] and with a speed of 5 cm/min ± 5.0 %. At other temperatures the speed should be specified.
