Effect of anisotropic base/interlayer on the mechanistic responses of layered pavements

Material anisotropy and thin interlayer are very common in layered pavement structures. Despite many numerical approaches in pavement analysis, very few theoretical methods are available in dealing with these two important issues. Thus, this study is focused on the effect of anisotropy and thin interlayer on the mechanistic responses of layered pavements. This is done using our analytical solutions based on the propagator matrix method in terms of the cylindrical system of vector functions. Our numerical results show that both anisotropy and thin interlayer could substantially contribute to the pavement responses.
