Article Preview

A laboratory investigation was carried out on the volumetric properties of WMA fabricated using the Superpave gyratory compactor (SGC) and the Marshall compactor as a function of compaction temperature. The volumetric properties were obtained and analyzed at the six compaction temperatures 170°C,150°C,130°C,110°C,100°C,90°C. The results show that: Evotherm® can improved the compatibility of the mixtures; Warm Mix Asphalt is sensitivity to the temperature when the compaction method is Marshall; the method of SGC is conducive to dense asphalt pavement for WMA; the best compaction temperature of WMA is not lower than 125°C; the compaction temperature can decreased more than 20°C for WMA comparison with the HMA.
