通过对高等级公路沥青路面病害分析 ,将病害产生的原因分为结构性破损和功能性破损两大类 ,从而将路面养护工程分为维修保养工程和大中修工程 (包括专项工程 ) ,从而总结出了四种养护方法。其中 ,维修保养工程有两种施工方法 ,分别是小面积修补法和补缝处理法。大中修工程分为大面积修补法和路基处理法。针对以上四种不同的施工方法 ,参考了国外的施工经验 ,对每一种施工方法又以“科学、安全、高速、快捷和有效”为原则 ,总结了四种不同的施工工艺过程 ,对不同的施工工艺 ,选择不同的养护设备 ,而且 ,对主要养护设备进行了比较具体的参数选择 ,对我国高等级公路沥青路面养护设备选型有一定的指导意义 By analyzing the disease of asphalt pavement in high-grade highway, the cause of the disease is divided into two major categories: structural damage and functional damage, so as to divide pavement maintenance works into maintenance and repair works and large and medium-sized repair works (including special projects) Summed up the four conservation methods. Among them, there are two construction methods of maintenance projects, namely, small area repair method and repair method. Large and medium repair project is divided into large area repair method and subgrade treatment method. Aiming at the above four different construction methods and referring to the overseas construction experience, the author summarizes four different construction process procedures for each construction method based on the principle of “scientific, safe, fast, efficient and effective” Of the construction process, choose a different maintenance equipment, and the main maintenance equipment were more specific parameters, the selection of high-grade highway asphalt pavement maintenance equipment has some guidance
