随着国家对公路建设的不断投入,我国公路建设的速度不断加快,大部分公路路面是由半刚性基层组成的沥青混凝土路面,而公路沥青混凝土路面表面层受雨水和车轮辗压的作用,容易出现表面层松散、坑洞、拥包、纵横向裂缝等现象。这些病害一般都与水密切相关,以此为出发点,本文介绍了沥青混凝土路面水损破坏破坏的特征,并详细分析了水损破坏产生的原因以及防治措施。研究结果对提高路面使用性能,延长使用寿命具有十分重要的意义。
With the continuous investment in highway construction in our country, the speed of highway construction in our country is accelerating. Most of the highway pavements are asphalt concrete pavements composed of semi-rigid grassroots, and the surface layer of highway asphalt concrete pavement is easily affected by rain and wheel rolling. Surface layer appears loose, potholes, Yong Bao, vertical and horizontal cracks and other phenomena. These diseases are generally closely related to water. Based on this, this paper introduces the characteristics of water damage damage of asphalt concrete pavement, and analyzes the causes and prevention measures of water damage. The research results are of great significance to improve the performance of pavement and prolong the service life.
