Abstract
Pavement primary responses (i.e. stresses, strains and displacements) due to horizontal loading have normally been determined by methods based on static analysis. However, when brakes are applied on the wheels of a moving vehicle or airplane, it is more realistic to consider the resulting horizontal load as dynamic and not static. In this paper, mechanistic properties of pavement layers are represented by Voigt model while displacements are explained in terms of three potentials. After that, closed form solutions are derived by using Hankel transform together with Fourier Transform. Comparing the results with the ones obtained from ADINA, a commercial Finite Element Method (FEM) package, confirms the validity of the derived solutions. Propagation of pavement responses in the vertical and horizontal directions due to dynamic horizontal loading is presented. The effect of coefficient of friction on pavement responses is also investigated by evaluating the results due to dynamic vertical and moment loading and presented in this paper.
