Standard Method of Test for Rutting and Fatigue Resistance of Asphalt Mixtures Using Incremental Repeated Load Permanent Deformation (iRLPD)

Abstract

This standard describes a test method for measuring the resistance of asphalt mixtures to rutting and fatigue cracking using minimum strain rates (m*) from an incremental repeated load permanent deformation (iRLPD) test conducted by means of a dynamic testing system (DTS).

This practice is intended for dense- and gap-graded mixtures with nominal maximum aggregate sizes to 37.5 mm.

This standard 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 procedure to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to its use.
