Phạm vi áp dụng / Scope of standard

This standard provides procedures for determining the tensile creep compliance at different loading times, tensile strength, and Poisson's ratio of hot mix asphalt (HMA) using indirect loading techniques.

The procedures described in this standard provide the data required to conduct the thermal cracking analysis. These procedures apply to test specimens having a maximum aggregate size of 38 mm or less. Specimens shall be 38 to 50 mm high and 150 ± 9 mm in diameter.

This test may involve hazardous materials, operations, and equipment. This standard 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.
