摘　　要：为研究基于SBS热塑性弹性体系的高黏弹改性剂在北方地区高速的应用效果,分别从高黏弹改性剂的研发、现场改性工艺、配合比设计、混合料性能测试以及现场检测展开试验。结果表明:高黏弹改性剂添加到基质沥青中,能够有效改善北方地区夏季高温条件下的抗车辙性能,冬季低温条件下的抗开裂、抗水损能力以及长期耐久性。很大程度上满足了沈阳的气候条件和交通条件,可为同类项目工程提供技术参考。In order to study the application effect of high-viscosity elastic modifier based on SBS thermoplastic elastomer system in high-speed roads in northern areas,this paper conducts research from the following aspects:the development of high-viscosity elastic modifier,on-site modification process,mixture proportion design,performance test of mixture,and on-site inspection.The test results show that adding high viscoelastic modifier to the base asphalt can effectively improve the anti-rutting performance,anti-cracking,water damage resistance,and long-term durability of asphalt pavement in the northern region under summer high temperature conditions and winter low temperature conditions.It can largely meet the climate and traffic conditions of Shenyang and provide technical reference for similar projects.
