摘要
上世纪修建的水泥混凝土路面破损严重,路面改造时为了解决半刚性基层沥青路面的反射裂缝问题,设计采用新型基层结构形式——水泥乳化沥青稳定碎石基层,提高路面整体结构的抵抗变形和抗裂缝能力。结合安徽省道S320沿江二级公路铜陵段旧水泥混凝土路面改造工程,介绍在旧水泥混凝土路面上加铺水泥乳化沥青稳定碎石基层的结构设计和施工方法。
The pavement breakage of cement concrete roads built last century was serious.In order to solve the problem of reflection crack in the bituminous pavement of semirigid base course,a new construction of base course of cement emulsified bitumen stable gravel bottoming was designed and used to enhance the resistance against the deformation and crack of overall pavement structure in road reconstruction.Design of the reconstruction of the old cement concrete road paved with cement emulsified bitumen stable gravel bottoming was introduced along with the pavement reconstruction project of the cement concrete road in Tongling section,as a part of Anhui provincial B road S320 down the Changjiang River.
