摘要
针对超龄沥青路面结构破坏严重 ,不能按时进行大、中修 ,而小修又起不到作用的情况 ,结合工作实践阐述了粗粒料处治旧沥青路面施工工艺 ,指出该施工工艺简单 ,费用低 ,对基层强度不足 ,面层龟。
According to the structural destroy of existing asphalt pavement and combined with construction experiences the construction technology of utilizing coarse grained material to treat existing asphalt pavement is elaborated. This technology is simple and with low cost, which has obvious effects for inefficient strength of base and map cracking of asphalt pavement.
