• There are two approaches for the pavement analysis, deterministic and probabilistic. Most of pavement analysis are based on the deterministic approach. In order to account the random variations of the material properties within the pavement system, a more realistic method is the probabilistic approach, in which the materials variables are given a mean and variance. The effect of variation layer properties of pavement on surface defections and strains in the pavement system are studied by sensitivity analysis. This is done by using a stochastic finite element based on the perturbation method which is based on the Taylor expansion. The results show the variation of surface deflections and strains in the pavement are related to the variation of layer moduli. Once the probabilistic properties of pavement response are known, the reliability of pavement design can be evaluated.
