ABSTRACT
Numerical modelling in pavement analyses has increased in complexity. Recently, Lee (2014) developed an algorithm named ViscoWave to simulate pavement dynamics under Falling Weight Deflectometer (FWD) loading. ViscoWave uses continuous integral transforms which are able to accurately simulate the dynamics response of the pavement. Similarly, Yan et al. (2014) evaluated wave propagation using an analytical layer-element approach under the FWD loading conditions. Using the global stiffness matrix equation from the multilayered pavement, a realistic solution is obtained through the Fourier-Hankel transform. Xu and Prozzi (2014) compared static against viscoelastic wave propagation analysis techniques using FEM. Findings for frequency spectrum, modal shape, deflection, stress, and strain were evaluated. It was found that wave propagation contributed to the time delay of deflections. In addition, including viscoelastic properties produced more accurate deflections and tensile stresses when compared to quasi-elastic analysis.
