Abstract:
A series of 3D finite element analysis was performed by ABAQUS to quantify impact of base and subbase resilient modulus on transverse shoving deformation in asphalt pavement with semi-rigid base. Mohr Coulomb constitutive model was applied to simulate the AC behavior and the liner elastic constitutive model was used for the other layers. The impacts of base and subbase resilient moduli on transverse shoving were respectively reviewed according to the comparison of displacement distributions in asphalt pavement with the base or subbase resilient moduli. The results show that the transverse shoving in AC layer can be effectively reduced through adopting base with relative lower resilient modulus. Relative higher resilient modulus of subbase is beneficial to transverse shoving mitigation, but the effect is not notable comparing with the decrease for base resilient modulus.
