Abstract

Abstract: In order to verify the application effects of pavement reinforcement technology with RoadMesh steel wire mesh, and relied on the S415 Reconstruction and Extension Project from Xiapuzhen to Jietoutang in Tongshan County, Xianning City, Hubei Province, the application researches on construction technology and treatment effect of RoadMesh reinforcement were carried out for the joint section between new and existing asphalt pavement through scheme design, field construction, tests and analysis and economic comparison. The results show that the tensioning and fixing of RoadMesh are the key construction processes, and the arching and rolling of RoadMesh should be strictly prohibited during its construction. The asphalt pavement performances of RoadMesh reinforcement is better than that of unreinforcement, and the reinforcement effect between lower surface layer and base layer is better than that between base layer and subbase layer. The RoadMesh can effectively improve the integral bearing capacity of asphalt pavement structure and the resistances of reflection cracking and differential settlement in the joint section between new and existing pavement. Compared with the traditional reinforcement of geotechnical synthetic materials, the RoadMesh has higher performance price ratio and better long-term pavement performances. Therefore, the pavement reinforcement technology of RoadMesh can be widely popularized and applied.
