在高速公路建设不断发展的过程中,多数沥青路面在未达到使用年限时已经出现不同程度的裂缝、车辙、坑槽等病害,因此高速公路沥青路面的大修施工成为公路养护部门的重要工作,由于高速公路沥青路面大修技术规范还不够完善,因此在技术方面存在一些问题,难以满足大修设计需求。本文结合本文结高速公路沥青路面的主要病害和原因,探讨了不同大修施工技术的应用。
In the process of continuous development of expressway construction, most asphalt pavements have suffered different degrees of cracks, rutting and pit damage when their service life has not reached. Therefore, the overhaul construction of asphalt pavement on expressway has become an important work of highway maintenance department. Highway asphalt pavement overhaul technical specifications are not perfect enough, so there are some technical problems, it is difficult to meet the needs of overhaul design. In this paper, the main road diseases and causes of expressway asphalt pavement, discusses the application of different overhaul construction techniques.
