The design of pavement involves a study of soils and Wiring Harness paving materials, their response under load for different climatic conditions.In the present study, an attempt has been made to compare stresses predicted using two finite element analyses.First analysis is based on the twodimensional plane strain assumption where as in second approach axi-symmetric condition is assumed to consider three-dimensional behavior of rigid pavement.

The results Collections are compared with flexural stresses obtained from conventional Portland Cement Association method.The computed flexural stresses obtained from axi-symmetric condition are found to be in close agreement with PCA method.Results of plane strain analysis show a fair agreement after application of an appropriate multiplication factor.
