• Abstract:
  Permanent deformation or rutting is a major hot mix asphalt (HMA) performance distress. Implementation of the ; Superior Performing Asphalt Pavement (Superpave) HMA mix design system was due, in part, to limit HMA rutting. ; Along with the Superpave system, performance testing equipment was developed to evaluate rutting potential; ; however, this equipment proved largely ineffective. As a result, agencies developed their own performance ; equipment, with the Asphalt Pavement Analyzer (APA) currently being used by many agencies for HMA rutting ; evaluation. ; The Mississippi Department of Transportation (MDOT) is utilizing the APA to evaluate HMA performance, but does ; not currently have established pass/fail criteria. Field rutting analysis and coring were conducted for twenty-four ; pavements throughout Mississippi to determine in-service performance. Asphalt pavement analyzer testing was ; conducted on field cores and lab prepared specimens to evaluate mix characteristic influence on rutting and to develop ; APA failure criteria. Based on the analysis, an APA rut depth criteria of 6.0 mm was established for HT mixes and ; 12.0 for ST and MT mixes.
