摘要
从温度收缩和干燥收缩两个方面,阐述了路面半刚性基层裂缝产生的机理,并在此基础上,分别从半刚性基层材料、半刚性基层的施工过程以及在半刚性基层中设置预切缝三方面提出了半刚性基层裂缝的防治措施。
The formation mechanism of the cracks of semi-riNd base course is discussed in two factors of thermal shrinkage and dry shrinkage. And on the basic of the discussion, the prevention measures of the cracks are presented from three aspects, which are semi-riNd base materials, the course of base construction and setting pre-cutting cracks in semi-rigid base courses.
