spatial distribution of displacements, stresses and strains in the multilayered pavement
systems. Hence, such empirical approaches are considered to possess only limited
capabilities.
The mechanistic-empirical (M-E) approach is based on the limited use of the
principles of mechanics such as elasticity, plasticity, and viscoelasticity. It involves two
steps. In the first step, the layered pavement system is analyzed by using a mechanistic
