水泥稳定碎石基层裂缝防治方法

水泥稳定碎石基层裂缝是当前施工中不易克服的问题，也是造成路面损坏的一个重要因素。根据水泥稳定碎石基层裂缝产生的机理，结合工程实践，提出了降低水泥用量、控制细集料含量、适时掌握切缝时间以及采用大厚体积水泥稳定碎石和设置柔性基层等方法，降低或延缓基层裂缝的产生，从而提高沥青路面使用性能。

Method for controlling cracks in cement-stabilized macadam base course

Cracking in cement - stabilized macadam base course is a problem not easy to be eliminated during construction, and also is an important factor causing damage of pavement. According to the mechanism of cracking in the base and the practice of projects, this article presents some measures for controlling the cracks, such as reducing the cement content, controlling the fine aggregates content, controlling properly the joint - cutting time, using the mass cement - stabilized macadam and providing with the flexible base, to reduce or retard the occurrence of cracks, thus improving the use performance of asphalt pavement.
