iRLPD Rutting (AASHTO TP 116)
(incremental Repeated Load Permanent Deformation)

  • Test can be performed on field cores or volumetrics
  • Takes only 33 min. to create MSR master curve, which determines resistance of a mixture to rutting at any temperature and under any stress
  • Determines allowable traffic
