ABSTRACT: Within the framework of a
FEM of the nonlinear behavior of lateritic pavement of Senegal, the effect of
truck overloading is studied to estimate its impact on the deformability of
road pavement on compacted gravel lateritic soils. For that purpose, various
loading conditions were tested to measure the impact on the critical response parameters
of road pavement design. The implementation of the models was realized with
Cast3M©. This study allowed us to point out that the observed
variations are linear and would help to plan in advance the impact of axle
overloads for a better evaluation within the framework of the mechanistic (M.
E.) design of pavements.
