摘要
采用橡胶粉和抗车辙剂对沥青混合料进行改性,对不同改性沥青混合料的高低温性能、水稳定性能和耐疲劳性能进行对照试验。分析了橡胶粉和抗车辙剂的共同作用机理,验证了采用橡胶粉和抗车辙剂进行复合改性可以使沥青混合料兼有2种材料分别改性的优点,具备更加优良的路用性能。
Asphalt mixture is modified by rubber powder and anti-rutting agent,and comparison test is carried on to determine the high and low temperature performance,water stability and fatigue performance of all types of modified asphalt mixture. The effect mechanism of rubber powder and anti-rutting agent on the asphalt mixture is analyzed. The test results show that use rubber powder and anti-rutting agent compound modification can tages of the two kinds material,then make it have more excellent make the asphalt mixture has the respective modification advan- pavement performance.
