ASSESSING THE RELATIVE RUTTING SUSCEPTIBILITY OF HMA IN THE LABORATORY WITH THE ASPHALT PAVEMENT ANALYZER

The Strategic Highway Research Program identified rutting as a major cause of distress for Hot Mix Asphalt (HMA) pavements. The resulting Superior Performing Asphalt Pavements (Superpave) mix design system specifically addressed the aggregate and asphalt binder properties that contribute to permanent deformation. The Superpave system, however, does not currently include a lab proof-test to quickly assess the rutting susceptibility of HMA. An Asphalt Pavement Analyzer (APA) has been developed and various lab studies have been conducted to assess the suitability of this device as a proof-test for HMA. A joint Tennessee Department of Transportation/University of Tennessee study was initiated to further evaluate the merits of the APA. In this study, over 30 mixes from various locations across the state of Tennessee were tested in the APA. Results of this study indicate that the APA is sensitive to critical material properties that have been documented to contribute to rutting of HMA on the roadway.
