Abstract

To predict pavement responses and performance due to external working loads, it is necessary to estimate stresses and deformations through pavement. When the induced strains are relatively small, they are usually evaluated using the theory of elasticity. Boussinesq's theory is used for this estimation through homogeneous soil. These responses in case of layered pavement system are less than those obtained for the ideal homogeneous case depending upon the stiffness of the layers. Semianalytical solutions are available to analyze the behaviour of elastic layered soil deposits subjected to surface loads. For more complex cases of soil deposits or loading conditions, it is necessary to perform numerical analysis using finite element technique. In addition, most of pavement materials do not linearly perform under the action of traffic loading. In this paper, the ANSYS version-8 program is used to analyze in three dimensions the behaviour of a layered pavement system under static loads indicating load transmission issues for a wide variety of materials stiffness, tire pressures and axle loads with dual wheels. Also linear and non linear analyses were preformed for different previously mentioned items. In this research, the pavement is modeled as a multilayered elastic system composed of a subgrade assumed to be an infinite medium upon which layers of finite thickness infinitely extended horizontally are laid. Furthermore, it is assumed that vertical loading, such as dual wheel loads are simultaneously applied to obtain stresses and deflections through the road pavement. On the basis of this research, remarkable conclusions are drawn out.
