This paper investigates the ability of a generalized Westergaard model consisting of a viscoelastic plate on a viscoelastic Winkler foundation to describe deflections of both rigid and flexible pavements under dynamic loading. The pavement response to falling weight deflectometer (FWD) loading was simulated, and a semianalytical solution involving the use of a Hankel transform in space and a finite difference method in time was developed. The obtained solution was used to interpret FWD data collected at the Minnesota Road Research Facility. It was shown that a good match between the simulated and measured response data could be obtained for both rigid and flexible pavements if inertia and viscoelastic effects were accounted for. The proposed model is thus an attractive tool for analysis of pavement–vehicle interaction.
