道路工程基层裂缝处理施工技术研究分析

Research and Analysis of Construction Technology of Crack Treatment of Road Engineering Base

根据道路路基面层裂缝的大小及沥青路面沉降程度将裂缝分为裂缝处理I区及裂缝处理II区。施工技术工艺概况:先采用地聚合物对路基进行注浆加固,然后刨除现状沥青面层及水泥稳定碎石基层,再重新铺筑沥青稳定碎石层,最后施工封层及沥青面层。沥青表面处治施工各工序应紧密衔接,撒布各层沥青后均应立即用集料撒布机撒布相应的集料,应在碾压结束后开放交通,同时做好初期养护与管理。

According to the crack size of the pavement surface layer and the settlement degree of asphalt pavement,the cracks are divided into the crack treatment zone I and the crack treatment area II.Construction technology overview:firstly,the subgrade is reinforced by grouting with ground polymer,then the existing asphalt surface layer and cement stabilized macadam base are planed,then asphalt stabilized macadam layer is re paved and finally the sealing layer and asphalt surface layer are constructed.The construction procedures of asphalt surface treatment shall be closely connected.After spreading asphalt,the aggregate spreader shall be used to distribute the corresponding aggregate immediately.Traffic shall be opened after rolling and the initial maintenance and management shall be done.
