Pavement Response due to Torsional Surface Loading

Resumé

When heavy vehicles such as truck and trailer make a sharp turn, it is known that torsional as well as vertical loads are exerted on the pavement surface. However, analytical solution of elastic multi-layered systems is not known. This paper presents the solution for multilayered elastic systems subjected to uniformly distributed torsional loading over a circular area. By combining this solution with the solutions of uniform vertical loading on the same circular area, one can estimate pavement response due to both types o f loadings.
