This paper deals with the behavior of an idealized multilayer structure representing an idealized pavement, observed using a numerical simulation. The investigated layered structure is constituted by the asphalt layer commonly called the road made of bituminous material, a layer of clean aggregate (gravel) and a foundation layer of soil mass. The numerical model was developed with respect to the geometry, dimensions, boundary and loading conditions of a physical model investigated by a previous researcher. After validation, the numerical model was used in a parametric study to show the effect of different parameters as the Young’s modulus of the materials, the temperature effect and the type of loading. Emphasis was put upon the behavior of the structures when subjected to static and cyclic loadings induced by the normalized stress of a wheel. The irreversible deformation of the road surface, usually called rutting was investigated. Out of this numerical exercise it was found that the deflection associated with rutting, considered as a residual displacement, is mainly due to the effect of the cyclic loading of the structure.
