多碎石沥青混凝土路用性能的研究

Study on Stone Asphalt Concrete Performance

研究了掺与未掺木质素纤维的多碎石沥青混凝土的路用性能 ,其中包括马歇尔稳定度、水稳定性、低温抗裂性、高温稳定度、疲劳耐久性和抗滑性能 ,并与密级配沥青混凝土进行了对比 .结果表明 。

According to experiment, the characteristics of stone asphalt concrete(SAC) performance, including Marshall stability, high temperature rutting, low temperature crack resistance, water stability, fatigue resistance and skid resistance were systematically analyzed. The influence of wood fiber on SAC performance was investigated, moreover, SAC is compared with dense grade asphalt concrete. The result indicates that SAC is a kind of high performance bituminous mixture.
