关于沥青砼路面水稳基层设置伸缩缝的研究

在沥青砼路面水稳基层中设置伸缩缝,目前在设计、施工技术规范中尚没有明确的规定,对这方面的研究亦通常被人们所忽视.笔者通过大量的施工经验,在深入分析、研究沥青砼路面早期病害的基础上,大胆尝试水稳基层设置伸缩缝的做法,并取得理想效果.笔者在揭示水稳基层温度应力的基础上,通过实例阐述沥青砼路面水稳基层伸缩缝的设置方法.

Research on setting expansion joint on water-stabilization bases of asphalt concrete road surface

Now in the design and construction technical specification, there is no specific regulation on setting expansion joint on road surface bases, research in the aspect also is generally neglected. On the basis of in-depth analysis and study on early distress of asphalt concrete road surface, depending on a great deal of construction experience, the author audaciously experiments with new method of setting expansion joint on water-stabilization bases and acquires expected effect. This paper not only opens out thermal stress of water-stabilization bases, but also expounds the method how to set expansion joint on water-stabilization bases of asphalt concrete road surface through examples.
