Laboratory Performance Testing of Warm-Mix Asphalt Technologies for Airfield Pavements
This report presents results from testing warm-mix asphalt (WMA) mixtures designed for airfield pavements. The study was conducted in two phases. The first phase included laboratory tests on 11 WMA technologies. The tests in Phase 2 were performed on three WMA mixtures and one hot-mix asphalt (HMA) mixture produced in an asphalt plant. The evaluation included performance tests to assess WMA susceptibility to permanent deformation and moisture damage compared to HMA produced using the same aggregate blend. Although WMA exhibited poorer performance than HMA in moisture damage tests on laboratory-produced specimens, the plant-produced mix indicated very little difference compared to HMA. Rutting potential for WMA was initially somewhat greater than for HMA for mixtures produced both in the laboratory and in an asphalt plant. Differences in performance among WMA mixtures were not attributed to a specific WMA technology category. Variations in performance test results between laboratory-produced specimens and plant-produced specimens were noted, indicating a need to require performance testing as part of a comprehensive quality assurance plan. Based on the laboratory performance test results of this study, WMA is a viable alternative to HMA for wearing surfaces on airfields.
