摘　　要：为了延长排水路面的服役年限,改善沥青混合料抗飞散、抗剥落的能力,采用胶粉与SBS复合改性高粘沥青为胶结料;通过对混合料的高低温性能、渗水性、水稳定性等指标的评价,表明复合改性高粘沥青混合料能满足排水路面的技术要求;工程应用表明复合改性高粘沥青具有较好的耐久性、耐水性及抗剥落性。In order to extend the service life of drainage pavement and improve the anti-stripping performance of asphalt mixture,SBS composite modified high viscosity asphalt with rubber powder is adopted as binder.Evaluating the high temperature performance,low temperature performance,water permeability,water stability and other technical indexes of high viscosity asphalt mixture,results demonstrate that the performance of composite modified high viscosity asphalt mixture can meet the requirements of drainage pavement.The engineering application showing that the chosen composite modified high viscosity asphalt performance well in durability water stability and anti-stripping.
