摘　　要：为了研究SBS改性剂对沥青混合料路用性能的改善效果,文中以新建城市主干路AC-13 SBS改性沥青混凝土路面上面层为研究对象,通过分析发现,掺加SBS改性剂的沥青混合料在高稳定性、低温抗裂性和耐久性等路用性能方面提升显著,可适应极端气候与重载交通等不利因素的周期性作用。In order to study the improvement effect of SBS modifier on pavement performance of asphalt mixture and its construction application,the paper takes the upper layer of AC-13 SBS modified asphalt concrete pavement of a newly built urban main road as the research object.Through analysis,it is concluded that asphalt mixture mixed with SBS modifier can significantly improve pavement performance in terms of high stability,low temperature crack resistance and durability.It can adapt to the cyclical effects of adverse factors such as extreme climate and heavy traffic.
