Rutting is one of the most critical failure mechanisms in New Jersey's flexible pavement roadways. A current technology in the asphalt pavement testing industry involves the use of a loaded wheel-tracking device as a tool for predicting a pavements tendency for rutting. However, an industry-wide standardized set of testing criteria does not exist. Consequently, the state agencies and universities have experienced an array of conflicting results. Currently, the New Jersey Department of Transportation (NJDOT) is developing pass/fail criteria for asphalt samples tested in a loaded wheel-tracking device. Results from this study will be used to assist in the NJDOT project. The objective of the study was to evaluate the effect of mix gradations, compaction methods, sample geometries, and testing configurations on rutting potential of hot mix asphalt (HMA) mixtures.
