水泥混凝土路面裂缝成因及预防措施

Reasons and Avoiding Methods of Cracking in Cement Concrete Pavements

全面分析水泥混凝土路面裂缝的主要成因,包括塑性收缩、沉降、干燥收缩、温度收缩以及自收缩。从材料配制和施工技术两方面深入探讨预防水泥混凝土路面早期裂缝,提高路面质量的有效措施。

The main factors which may cause the cracking of cement concrete pavements are summarized,including the plastic shrinkage,settlement,drying shrinkage,temperature gradient and autogenous shrinkage of concrete.Both from the aspect of materials and constructions,efficient strategies which can be adopted to avoid cracking of cement concrete pavements are proposed.
