Abstract: The nonlinear models of pavement base and subgrade were briefly reviewed. Subroutines of the three-dimensional finite-element analysis in the ABAQUS package were developed for nonlinear behavior of a coarse-grained base ...

Abstract: The writers recently developed a nonlinear viscoelastic-viscoplastic constitutive model, in order to represent the response of asphalt mixtures under different temperatures and rates of loading. This model has been implemented ...
