Rotation of Stresses in French Wheel Tracking Test

The main function of a pavement is to distribute the traffic-induced load over its different layers. While flexible design methods are based on linear elastic calculation, real behavior layers highly non-linear and elastic. They can also, in some cases, be plastic viscous. This research aims develop three-dimensional numerical model that closely similar test FWTT conditions. will have geometry wheel footprint (rather than rectangular shape). As substitute for incremental loading, movement during passage specimen simulated by horizontal displacement. These important characteristics represent novelty major difference between current previous studies. model, which finite elements method, uses Abaqus software viscoelastic constitutive model. materials' properties been described Prony series, also called relaxation modulus, time. parameter defined most computer-aided engineering (CAE) software. procedure calculating series from experimental data explained. results obtained agree with stress signal amplitude, rotation principal, total displacement when approaches node considered located middle specimen.
