Mechanistic Analysis of Rigid Pavement for Wheel Load Stresses by Finite Element Method Considering Different Sub-Grade

摘要

In this research work it was aimed to generate charts for flexural stresses due to wheel loads using finite element method. ANSYS software is basically software for finite element technique. For generating the charts, edge loading condition was considered which critical case for wheel load stresses is. The pavement slab has been analysed for different axle loads and subgrade using finite element method, and results are compared with Westergaard’s analysis. Also it was aimed to compare the results with those given by Westergaard’s solution and IRC 58 – 2002 design charts.
