摘要
大粒径沥青碎石常被用于解决旧水泥混凝土路面加铺改造中普遍存在的反射裂缝问题。为寻求大粒径沥青碎石缓解层沥青路面的结构设计方法,对设置该缓解层的沥青路面进行温度应力分析,找出了大粒径沥青碎石缓解层对路面结构应力分布的影响规律。
Large particle asphalt macadam is often used to solve the problem of reflective cracking in old cement concrete pavement reconstruction project.In order to find the structural design methods of asphalt pave-ment with large particle asphalt macadam relief layer,this paper analyzes the temperature stress of asphalt pave-ment which has relief layer and finds out the influence of large particle asphalt macadam relief layer on stress distribution of pavement structure.
