Numerical Analysis on Influencing Factors of U-shaped Disease of Asphalt Pavement Using ABAQUS Program

摘要：

　　The U-shaped cracking of high-grade semi-rigid base asphalt pavement was studied.A finite element program (ABAQUS) was used to conduct a mechanical model to analyze the effects of the interlayer conditions and overloads on U-shaped cracking.The results show that the generation and development of U-shaped cracking is significantly influenced by interlayer conditions and overloads.Furthermore,the asphalt-to-asphalt pavement layer conditions provide for a more remarkable effect on U-shaped cracking than the asphalt-to-base pavement layer conditions.To reduce the development of U-shaped cracking,two aspects work must be reinforced:(1) the interface conditions should be improved to ensure the shear strength between layers of surface course and avoid slippage failure between layers of asphalt pavement,(2) over loading vehicles must be limited.
