Numerical Analysis of Porous Concrete Base in Asphalt Pavement Based on Traffic Load

Abstract:

Traffic load is important parameter used in the analysis of the new pavement design. However, few studies have done extensive and intensive research on the load stress for asphalt pavement of porous concrete base. Because of that, it is necessary to study the stress of porous concrete base in the asphalt pavement based on traffic load. In the paper, first of all, threedimension finite element model of the asphalt pavement is created for the aim of doing mechanical analysis for the asphalt pavement. And then, the two main objectives of this study are investigated. One is calculation for load stress of porous concrete base, and the other is analysis for load stress of porous concrete base. The results show that load stress of porous concrete base decreases, decrease and increase with increase of bases thickness, surfaces thickness and ratio of bases modulus to foundations modulus respectively.
