施工期水稳基层网裂检测及分析

Detection and Analysis of Water Stabilized Base Net-shaped Cracks During the Construction

水泥稳定碎石基层作为高等级路面一种主要的基层结构在公路建设中被广泛运用,但是由于施工期中许多不合理的因素,常常导致水稳基层出现裂缝,严重的甚至会出现大范围的网状裂缝,极大影响了公路的质量和使用寿命。文章通过对某一级公路水稳基层进行试验检测,分析其网状裂缝产生的原因,为解决施工期水稳基层出现的大范围网裂问题提供参考与借鉴。

The cement stabilized macadam base,as a major base structure for high-grade pavement,is widely used in highway construction,but because of many irrational factors during the construction,it often results in the cracks in water stabilized base,and in severe cases even the large net-shaped cracks may appear,which greatly affects the quality and life of highway.Through the experimental detection on the water stabilized base of a first-class highway,this article analyzed the causes of its net-shaped cracks,thereby providing the reference for addressing the large net-shaped cracks of water stabilized base during the con-struction.
