摘要
针对目前沥青路面公路养护大中修中病害处治方案单一和处治后沥青面层出现反射裂缝的现象,结合海西地区特殊地质、气候等条件,对海西地区养护大中修工程中病害处治方案进行系统分析,从新材料、新工艺入手选用抗裂贴处治大面积重(中)度龟裂,作为链接层,保证沥青面层不会出现反射裂缝。
In maintenance period of asphalt pavement, the treatment measures are simple and reflection cracks appear after treatment. Considering the special geological and climatic condition of Haixi, through analyzing relevant maintenance measures during the maintenance period in this region, the crack stick is introduced to deal with large scale cracks, which as the link layer, prevents reflection crack from appearing.
