Standard Method of Test for Determining the Damage Characteristic Curve and Failure Criterion Using Small Specimens in the Asphalt Mixture Performance Tester (AMPT) Cyclic Fatigue Test

Abstract

This test method covers procedures for preparing and testing both laboratory-compacted and field-cored asphalt mixture specimens to determine the damage characteristic curve and fatigue analysis parameters via the direct tension cyclic fatigue test using the asphalt mixture performance tester (AMPT).

This standard is intended for dense-graded mixtures with nominal maximum aggregate size up to 19.0 mm (0.98 in.).

Mixtures with a nominal maximum aggregate size greater than 19.0 mm (0.98 in.) should be tested following TP 107.

This standard may involve hazardous material, operations, and equipment.

This standard does not purport to address all safety problems associated with its use.

It is the responsibility of the user of this procedure to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
