摘要
在旧的水泥混凝土路面上加铺沥青混凝土层,提高原有路面的行车条件与使用寿命,是近年来较多路面大修工程采用的形式。探讨了一种突破地面标高限制、兼具结构性和功能性的沥青混合料GSOG-13,并借助在上海浦东三林地区的实体工程应用,验证"白加黑"延缓反射裂缝产生的双层沥青加铺层结构组合类型。
Adding asphalt concrete pavement layer on the old cement concrete pavement is more and more used in road repair engineering to improve driving conditions and service life in recent years.This paper discussed one asphalt mixture GSOG - 13,which owned both high structural and functional performance,and can break through ground elevation restrictions.The practical application at the Pudong San Lin area validated that double-layer asphalt overlay structure can delay reflection cracking propagation.
