Abstract:

In 2001, the Florida Department of Transportation (FDOT) conducted an experimental study to assess the effect of polymer modified PG76-22 asphalt binder on rutting resistance of Superpave mixtures through Accelerated Pavement Testing (APT). The success of this study led to the use of PG76-22 binder on the final structural course for traffic level D (10 to > 30 million equivalent single axle loads, or ESALs) mixtures and the top two structural courses for traffic level E (≥ 30 million ESALs) mixtures. At times, however, localized failures still do occur at locations with concentrated truck traffic and low speeds. In response, a follow-up APT study was conducted to evaluate the performance of a polymer-modified asphalt binder meeting PG82-22 requirements. Results of the study indicated that the use of a heavy polymer modified binder improved rutting and cracking performance of asphalt mixtures.
