摘要
该文通过试验研究,系统分析了多碎石沥青混凝土(SAC)的路用性能,包括马歇尔稳定度、水稳定性、低温抗裂性、高温稳定度、疲劳耐久性和抗滑性能,研究了添加木质素纤维对多碎石沥青混凝土性能的影响,最后与密级配沥青混凝土进行了对比分析。结果表明,多碎石沥青混凝土是一种性能优良的沥青混和料。
According to the experiment,the article systematically analyzes the road performance of stone asphalt concrete(SAC),included Marshall stability,water stability,low temperature crack resistance, high temperature stability,fatigue resistance and skid resistance.The article studies the influence of adding the lignin fiber on the performance of SAC,at last,compares and analyzes SAC with the dense graded asphalt concrete.The result indicates that SAC is a kind of high-performance asphalt mixture.
