[Abstract]:The basalt fiber reinforced continuous reinforced composite pavement is a new kind of long-life composite pavement which is formed by replacing the reinforcement with basalt fiber reinforcement to form a continuous reinforced concrete layer with a certain thickness of asphalt overlay. In this paper, the basalt fiber reinforced concrete composite long-life pavement is studied based on the Ministry of Communications and Transportation project "basalt fiber reinforced continuous reinforced concrete long-life pavement", and the basalt fiber reinforced composite pavement basalt fiber reinforcement test and construction technology are carried out. Based on the research of concrete structure, cement concrete pavement and other test methods and related contents at home and abroad, this paper designs the bond-slip performance test of basalt fiber reinforcement and concrete. The special bond failure phenomenon of basalt fiber reinforcement in concrete is observed, and the actual bond-slip relationship curve between basalt fiber reinforcement and concrete is determined. The bond-slip law between basalt fiber reinforcement and concrete is obtained, which provides the technical basis for the analysis of this type of pavement. The bond-slip constitutive model of basalt fiber reinforcement is compared with the experimental curve on the basis of experiment and other related experimental results. The model curve is in good agreement with the experimental curve. The finite element analysis model of bond slip between basalt fiber tendons and concrete is established by using the finite element software Abaqus. including the selection of element types and material parameters and the treatment of bond-slip finite element analysis between the two materials. The Abaqus simulation and solution of the central drawing test of basalt fiber tendons are carried out to verify the feasibility of the finite element model. According to the difference between this type of pavement and the common reinforced concrete continuous reinforced concrete composite pavement, the construction technology is compared and analyzed. This paper puts forward the design scheme of the test section of basalt fiber reinforced continuous reinforced composite pavement structure. The research work of this paper is supported by the National Ministry of Transportation Science and Technology Project of Traffic Construction (20113 188 25780).
