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.

Strength And Stiffness

Several investigators have extended the numerical analysis to model ground improvement using soil-column to support structures. Cement columns are widely used to improve the load deformity characteristics of soft soils. This technique would increase soil bearing capacity and reduces soil deformation owing to improving of soil strength and stiffness. The aim of this paper is to determine the rigid pavement structure deformity on soft soil for the cases of with and without column soil cement. Two geometrical models were used in this analysis: (a) without column soil cement and (b) with column soil. The result indicated that the presence of soil cement column considerably contributes to the decrease in deformation due to the increase in stiffness.
