摘　　要：选用SBS及橡胶粉对基质沥青进行复合改性来制备高粘复合改性沥青,以弥补沥青路面因大孔隙路面结构特点带来的性能不足。在2种70^(#)基质沥青中分别掺入4.5%的SBS和0%、6%、8%、10%、12%、14%的橡胶粉制备橡胶复合改性沥青,并对复合改性沥青进行3大指标、60℃动力黏度、135℃布氏黏度试验得出,橡胶粉推荐掺量为10%~12%。对复合改性OGFC-13排水式沥青混合料开展配合比设计及高温性能、水稳定性能、析漏及分散性能研究得出,SBS掺量固定为4.5%,橡胶粉掺量为12%时,2种橡胶复合改性沥青混合料高温抗车辙能力、抗磨耗能力性能最优,橡胶粉掺量为10%时,2种橡胶复合改性沥青混合料抗水损害能力性能最优。SBS and rubber powder were used to prepare high viscosity composite modified asphalt by composite modification of matrix asphalt,so as to make up for the lack of performance of asphalt pavement due to the structural characteristics of large pore pavement.Rubber composite modified asphalt was prepared by mixing 4.5%SBS and 0%,6%,8%,10%,12%and 14%rubber powder into Shell and Donghaizai 70^(#)matrix asphalt by a certain shear and stirring process.The three indexes of composite modified asphalt,dynamic viscosity at 60℃and Brinell viscosity at 135℃were tested.The recommended dosage of rubber powder is 10%-12%.Through the research on the mix ratio design,high temperature performance,water stability performance,leakage and dispersion performance of the composite modified OGFC-13 drainage asphalt mixture,it is concluded that when the SBS content is fixed at 4.5%and the rubber powder content is 12%,the Shell and Donghai rubber composite modified asphalt mixture has the best high temperature rutting resistance and abrasion resistance performance.When the content of rubber powder is 10%,Shell and Donghai brand rubber composite modified asphalt mixture has the best water damage resistance performance.
