|Abstract:||This paper develops a solution of warping stresses in concrete pavement slabs on a Pasternak foundation. The solution is derived using the classical thin-plate theory. Warping stresses in a slab of length A and width B is obtained by superposing the solution of a slab with length A and infinite width and that of a slab with width B and infinite length. It is shown that the commonly adopted traditional procedure of computing warping stresses. These stresses decrease as the subgrade shear modulus increases. Comparison with experimental measurements indicates that the present solution produced more accurate warping stress than those obtained using the Winkler foundation solution. The derived solution is presented in a dimensionless chart of warping stress coefficients for speedy evaluation of warping stresses in concrete pavements.|
