半刚性基层裂缝形成的原因及防治

On reasons for cracks on semi-rigid bases and their prevention

通过对半刚性基层裂缝形成的原因进行分析,指出了半刚性基层裂缝形成的原因是由混合料的设计和施工综合因素造成的。对半刚性基层裂缝的防治应从以下三个方面控制:原材料的质量、配合比设计、施工的过程控制。这样可以有效提高半刚性基层的施工质量。

The paper analyzes the reasons for the cracks on the semi-rigid bases,points out the cracks caused by the design of the mixtures and comprehensive factors of construction,and indicates the prevention should start from the three aspects,including the quality of the raw materials,design for the proportional ratio,and process control of the construction,so as to improve the construction quality of the semi-rigid bases.
