The importance of developing an analysis of the flexural behavior of beams is related firstly to the use of beams as a basic element in the realization of structures, and also to characterize the mechanical properties of laminates and sandwich materials from bending test performed on specimens shaped beams. Determining the mechanical behavior of pavement materials is used to calculate the distribution of stresses and strains in the pavement as the rigidity of the materials to determine the thickness to set up according to the resistance of these materials to different damage mechanisms, depending on climate and traffic. Comparison of the mechanical behavior of materials used to make a selection of the type of materials and interventions based on their performance. In addition, knowledge of the mechanical behavior of materials used to develop specifications based on the on the physical properties of these materials and selection criteria for the type of intervention based on a cost analysis of the life cycle. This study examines the mechanical behavior of a bituminous material quasi-compact. It aims to develop a pattern of behavior meets the requirements for industrial exploitation. Experimental responses show a behavior similar to that of concrete, namely the asymmetry. Only the normal stress is taken into account. Although for different layers, the normal distribution of the stress is linear and is based only on the depth of the beam. However, the stress distribution in the beam is not perfectly linear but piecewise linear.
