The effects of nominal maximum aggregate size (NMS), coarse aggregate type, fine aggregate angularity (FAA), and gradation types on HMA rutting performance were evaluated using the Purdue Laboratory Wheel Track Device (PURWheel). Correlation between PURWheel and Indiana Department of Transportation/Purdue University (INDOT/Purdue) Accelerated Pavement Tests (APT) was used as an initial step to field pavement rutting performance evaluation. Test results showed that PURWheel and APT are well correlated. This is positive because the traffic loading and compaction method used in the prototype scale APT is essentially identical to field conditions.
