RIGID PAVEMENT DESIGN CHARTS BASED ON A FINITE ELEMENT ANALYSIS

The finite element method is used to determine the stresses and deflections in rigid pavement slabs of finite size, for both central and edge loading conditions. The main variables considered are the thickness of the slab, the modulus of elasticity of the subgrade, and the values of the load and tire pressure. For the central loading case, the subgrade is treated as an elastic continuum. However, for the edge loading case, a Winkler's type model is assumed. The results are presented in the form of simple design charts which relate thickness to stresses. For the case of edge loads, new charts are developed for converting dual or dual tandem wheel loads to equivalent single wheel edge loads.
