摘要
通过采用高粘弹性SBS改性沥青设计了SMA-5沥青混合料,将该沥青混合料用于沥青路面超薄磨耗层的铺筑。研究了SMA-5沥青混合料的配合比设计,并通过在橡胶沥青碎石封层上铺筑SMA-5超薄磨耗层,研究了超薄磨耗层的现场拌合和铺筑工艺,分析了SMA-5沥青混合料的路用性能。
The SMA-5 asphalt mixture ultra-thin wearing course was prepared by high viscoelastic SBS modified asphalt.The proportion design of SMA-5 asphalt mixture was studied.By laying SMA-5 ultra-thin wearing course on rubber asphalt macadam seal,the field mixing and paving technology of ultra-thin wearing course was studied,and the road performance of SMA-5 asphalt mixture was analyzed.
