1.1This test method assesses the elastic recovery of an asphalt material measured by the recoverable strain determined after severing an elongated briquet specimen of the material of the form described in 4.1. The specimens are pulled to a specified distance 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?%.
