Refine AASHTO T283 Resistance of Compacted Bituminous Mixture to Moisture Induced Damage for Superpave

Moisture induced damage in asphalt concrete pavements, better known as stripping, is one of the primary causes of distresses in the asphalt pavement layers. AASHTO T283 has historically been used to detect moisture damage potential of asphalt mixes. This method is established for the Marshall mix design process. However, the current hot mix asphalt (HMA) design calls for the use of Superpave mix design procedure using the Superpave Gyratory Compactor (SGC). The differences in the mix design methods will most likely introduce significant differences in stripping test results. Therefore, to improve the AASHTO T283 test procedure and to develop the new criterion for the Superpave HMA specimens, this project was conducted to evaluate the applicability of AASHTO T283 to the Superpave mixes. A structured laboratory test program was conducted in this research to study the effects of the various factors on the HMA specimen's susceptibility to moisture damage. A complete factorial experimental program for two aggregate sources with virgin asphalt binder was conducted together with a partial factorial experimental program for the other two aggregate sources with polymer modified asphalt binders. In the data analysis, the effects of different factors on dry tensile strength, freeze-thaw conditioned tensile strength, and tensile strength ratio (TSR) were investigated in this report. The effects of all the factors investigated in this research are summarized in this report. The recommendations for the proposed stripping test procedure for Superpave HMA are given at the end of the report.
