Modeling a Road Reinforced by Geosynthetics

Abstract

Pavement construction is subject to the availability of good quality material, especially for the construction of the base and foundation layers. The use of geosynthetic reinforcement in these layers presents an interesting perspective on the shortfall. This research is in the context of the evaluation of the mechanical behaviour of flexible pavements reinforced by geosynthetics alveolar type of the AFITEX Company for which we started a modelling by the Software FLAC 2D Version 4 whose goal is to evaluate the deformations and the constraints. The pavement is subjected to a static loading of a value corresponding to 13 tons per axle.
