Research on the Construction Technology of Highway Reconstruction and Expansion Pavement Widening under the Condition of Ensuring Traffic
In view of the problem that the widening construction height difference of highway reconstruction and expansion pavement greatly affects the traffic quality of pavement,this paper studies the widening construction technology of highway reconstruction and expansion pavement under the condition of guarantee.By arranging the isolation pier of the pavement splicing section of the expressway reconstruction and expansion,the original speed limit sign in the reconstruction section is removed,and the speed limit sign and temporary isolation facilities are added.The original pavement of the milling expressway is re-paving the stable gravel base,milling the old road part,and paving the gravel asphalt concrete base.The pavement surface layer of the reconstruction and expansion of the expressway is sprinkled with sticky layer oil between the surface layers to ensure the splicing effect between the surface layers.Finally,the example is analyzed to verify the construction quality of the technology.
