Simplified modeling for multilayer of cracked pavement

Quang Dat Tran
Abstract : Most of design pavement models can not be used to simulate cracking in pavements. This problem can be modelled by using 3D finite element methods, but such calculations can be very time-consuming. In the objective to build a software for the evaluation of cracked pavements, and design solution for rehabilitation, we propose here to use a simplified plate model for bending problem linked to the Boussinesq model for the soil. The complete algorithm is programmed in the Matlab software. This model gives, very quickly, good approximations of the design stress fields near interfaces and vertical cracks in comparison with 3D finite element calculations. Thermal and shrinkage problem are studied and validated. In the aim to simulate some fatigue problems, a method is presented to accelerate the calculations.
