STRESSES IN FULL-DEPTH GRANULAR PAVEMENTS

Highway pavements for moderate to low-volume traffic often consist of granular materials topped with thin bituminous surfacing. The particulate bases transfer the stresses to the underlying layer by grain-to-grain interaction and cannot resist tensile stresses. The usual analysis of multilayer pavements requires the granular layers to possess tensile strength. A finite-element solution is presented for determination of stress in pavements made up of full-depth granular layers. In this method the tensile stresses computed in the elements of the graunular material by the elastic approach are eliminated during each iteration until the solution converges. The vertical stresses on the subgrade are found to be significantly higher than those obtained from linear-elastic analysis.
