This method is used to determine the elastic recovery of asphalt material through the use of a ductilometer and briquet specimens. The specimens are pulled apart at a rate of 5 cm/min (2 in./min) and held after a specified elongation. The specimens are then severed at the center and allowed to recover undisturbed for 1 h. Unless otherwise specified, the test shall be performed at a temperature of 25 ± 0.5°C (77 ± 1.0°F).
