Phạm vi áp dụng / Scope of standard

The force ductility of an asphalt material is determined by measuring the tensile stress induced on a specimen when two ends of a briquet specimen of the material are pulled apart at 5 cm/min (2 in./min) and at a specified temperature. Unless otherwise specified, the test shall be performed at a temperature of 4.0 ± 0.5°C (39.2 ± 1.0°F) and a speed of 5 cm/min (2 in./min) ± 5.0 percent. The test is designed primarily for polymer-modified emulsions.

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.
