Prediction Models for Computation of Deformations and Interface Stresses in a Two-Layered Pavement Structure

The granular layer, being the major structural component in low-volume roads, exhibits significant plasticity and undergoes both elastic and permanent deformation under repeated vehicular loading. Stress-dependent, nonlinear resilient moduli, as well as elastoplastic models, have been considered for characterizing individual pavement materials; however, very limited research is available that studies the composite behavior of granular material...
