某二级公路水稳碎石基层裂缝成因及防治措施浅析

Analysis on Causes and Prevention of Crack in Cement Stabilized Macadam Base of Certain Second Class Highway

水泥稳定碎石基层是我国公路路面广泛应用的基层结构形式,它具有强度高、水稳定性好的优点。但由于其结合料为水泥,施工工艺要求较高,而且需要较好的施工管理环境,否则就极易产生早期裂缝。从原材料、施工及养护管理等方面提出综合防治措施,以保证公路路面的正常使用。

Cement stabilized macadam base is the structure widely used for highway pavement in our country. It has the characteristics of high strength and good water stability. However since the binder is cement and the construction technical requirement is strict, good construction control environment is needed; otherwise early crack may be caused easily. The comprehensive prevention measures with respect to raw material, construction and maintenance are proposed to ensure the normal service of highway pavement.
