Standard Method of Test for Elastic Recovery Test of Asphalt Materials by Means of a Ductilometer
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.
The values stated in SI units are to be regarded as the standard.
This test may involve hazardous materials, operations, and equipment. This test does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
