Numerical Analysis of Asphalt Pavement of Lean Concrete Base
Both thermal stress and load stress, which are caused by temperature change and traffic loading, are important parameters used in the analysis of the new asphalt pavement design. In order to study the stress of asphalt pavement of lean concrete base, first of all, threedimension finite element model of the asphalt pavement of lean concrete base is established. The main objectives of the paper are investigated. One is calculation for stress of asphalt surface, and the other is calculation for stress of lean concrete base. The results show that load stress of lean concrete base increases quickly with the increase of load. Thermal stress of lean concrete base increases with the increase of thickness of base. Asphalt surface is in the state of compression. Maximum shearing stress decreases with the increase of thickness of asphalt surface.
