沥青类型对沥青混凝土路用性能影响的试验研究

Experimental study on influence of asphalt type against road performance of asphalt concrete

通过马歇尔试验,确定了不同沥青含量条件下AC-13Ⅰ的最佳沥青含量,进而对沥青混凝土的各项路用指标进行了车辙试验,水稳性试验及疲劳试验研究,结果表明,采用SBS改性沥青的混合料具有良好的路用性能,经济效益和社会效益。

By the Marshall test,the optimal asphalt content for AC-13Ⅰwith the different asphalt content is determined.And the rutting test,water stability test and fatigue test are operated on the road index of asphalt concrete.The results show that the mixture using SBS modified asphalt has better road performance,excellent economic and social benefits.
