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.
