In this research, two dimensional elastic analysis was applied to specimens composed of layers with several different types of pavement mixtures. This analysis was intended for the mechanical evaluation of pavement mixtures through bending test on both surface and binder courses, with a steel plate attached, as well as with a reinforcement layer between them. A series of numerical results obtained gave basic informations for evaluating pavement mixtures quality and their various elastic constants due to layer thickness, material quality and adhesiveness of interfaces.
