A coupled constitutive model based on hyperelasticity is proposed to capture the resilient behavior of granular materials used in pavement construction. The coupling property of the proposed model accounts for shear dilatancy and pressure-dependent behavior of the granular materials. The model is calibrated using triaxial resilient test data and the results of a three-dimensional finite element analysis of a sample pavement system are presented. A statistical comparison is made between the applied stresses of the test and the stress values predicted by the proposed model, the K-θ model, and linear elasticity corresponding to the measured strains.
