摘　　要：通过对不同Sasobit掺量的温拌改性沥青进行针入度、延度、软化点及粘度试验,得出合理的温拌剂掺加范围,并对推荐范围内不同温拌剂掺量的改性沥青的感温性能、高温性能、低温性能及疲劳性能进行研究,考察温拌剂掺量对温拌沥青流变特性的综合影响。The penetration test, ductility test, softening point and viscosity test of warm mix asphalt with different mixing amounts of Sasobit were carried out to get a reasonable mixing range of warm mix agent. The temperature sensitivity, high temperature performance, low temperature performance and fatigue performance of modified asphalt with reasonable Sasobit amount were studied to find out the influence of Sasobit mixing amount on the rheological property of warm mix asphalt.
