Abstract
It is, generally, known that when large-sized vehicles like trucks and trailers are turning left, vertical and turning (torsional) load are applied on the pavement surface. However, there is very little information in the literature on the analytical solution of a multilayered elastic structure subjected to torsional surface loading. This paper presents analytical solution based on uniformly distributed circular torsional load. Combination of the solutions for axi-symmetric load (already developed) and torsional load will enable engineers determine stresses, displacements, strains etc at any point within the pavement structure when torsional load acts at the pavement surface.
