Abstract
Pavement is modeled as an elastic structure composed of a semi-infinite body and layers of finite thickness extended infinitely in a horizontal direction. Load acting in a horizontal direction at the surface is uniformly distributed over a circular area. Navier's equation is solved analytically by employing Hankel transformation theory. Furthermore, using the principle of superposition, a program is developed, which can find the response of multiple shear loadings. Accuracy of the results is confirmed by comparing the results from BISAR using some example problems. The comparison shows that the stress outputs from BISAR yield erroneous results at the pavement surface.
