半刚性基层裂缝成因及处理方法探讨

Discussion on the causes of cracks in semi-rigid base course and their treatment method

结合工程实践,从路基不均匀沉降、集料特性、水泥剂量、施工气候、碾压含水量、施工工艺等方面对半刚性基层裂缝的成因进行了简要分析,并围绕尽量减少和延迟裂缝的发生提出了一些实用的施工处理方法。

Combined with the practical project, it makes simple analysis on the forming reasons of half steel rigidity basement cracks from many aspects including the uneven sinking of basement, material collection characters, cement doses, constructing climate, grinding water content and constructing craft. Based on reducing and ddaying the cracks＇ happening, it brings forward some practical constructing processing methods.
