碎石过渡层沥青路面在广西玉林的应用综述

Application of Crushed Stone Transitional Layer Asphalt Pavement in Guangxi Yulin

玉林地区自20世纪80年代开始在半刚性基层上铺设碎石过渡层,多年的施工实践表明,碎石过渡层沥青路面在保证路面质量的同时,可提高路面的使用耐久性和稳定性、减少半刚性基层裂缝向面层的反射、避免水对承重基层的冲刷,因此推荐该结构作为今后路网改造工程中优先考虑的路面结构。

Crushed stone transitional layer paved on semi-rigidity base has been applied in Yulin since 1980s. Many years of construction experiences show that crushed stone transitional layer asphalt pavement can guarantee pavement quality, at the same time it can improve durability and stability of pavement, decrease crack reflectance from semi-rigidity base layer to pavement layer, avoid bearing base layer eroding because of water. This kind of pavement can be used as the preferred pavement structure in the future road network reconstruction.
