Paper Title:
The Effect of Compaction Temperature on Volume Parameters of Warm Asphalt Mix with Sosabit
  Abstract

The volume parameters of asphalt mixtures is sensitive to compaction temperature. Warm-mix Asphalt (WMA) was green paving technology, which can allow paving at lower temperature. In this study, a laboratory investigation of the volumetric properties of WMA with Sosabit was carried out by the method of Marshall. And the effect of different asphalt such as modified asphalt such as Kalamay, Shell, SK and Kalamay 90# asphalt on volumetric properties of WMA at different temperature was analyzed. Based on this, the minimum compaction temperatures of WMA with Sosabit was proposed. The result showed that bulk density and VFA are decreasing and air voids and VMA increasing with the decreasing temperature; the volume indicators to meet the regulatory requirements when the temperature is 170°C~143°C for three WMA-SBS temperature and 150°C~115°C for WMA-90#; compaction temperatures of modified asphalt and asphalt mixture after adding Sosabit can lower up to 133°C and 118°C respectively.
