SummaryThe model developed tries to predict the stresses and strains of the structure of the pavement in a more real way, doing a lineal elastic structural analysis in three dimensions with capacity to model loads of double axes, that which constitutes an advance regarding twodimensional axisymmetrical models that only represent the state tense-deformational of the pavement under loads of simple axes. Earlier stages of this research showed two-dimensional models under different load scenarios, league between layers and nonlinear constitutive models, however the purpose is to move towards analysis methodology stress-strain state under standard loads. The model was implemented in the Algor© program and a comparison with the Elsym5 multilayer freeware was performed. The results warn the existence of shear stress concentrations that can be causing major flaws that are not considered in traditional design methods which could lead to the possibility of reassessed.
