MODEL OF A FLEXIBLE PAVEMENT. APPLICATION OF THE FINITE ELEMENT METHOD

UN MODELE DE CHAUSSES SOUPLE APPLICATION DE LA METHODE DES ELEMENTS FINIS

The principle of pavement design by a "rational method" consists of modeling the structure and using various methods to compute the stresses, strains, and movements caused by a typical loading condition. The values obtained are then compared to the limiting values for a given traffic situation. In this article, the authors deal with the design, using the finite element method, of a flexible pavement structure under uniform circular loading conditions. Within the context of linear elastic behavior of the materials, they examine the influence of the forces of gravity, boundary conditions, and Young's modulus. Analysis of the distribution of radial tensile stresses shows that another type of behavior of materials, closer to reality, must be adopted. A finite element model capable of taking these considerations into account is now being developed.
