Intermolecular interactions, density, bulk modulus and zero shear viscosity changes of model asphalt systems before and after oxi
dative aging and mechanical property changes of the asphalt systems under different compressive and tensile stress rates are investigated at room temperature (298K). Simulation results demonstrate that oxidid functional groups in asphalt molecules increa the strength of intermolecular bonds and the bulk modulus of asphalt, which further contribute to the hardening of the oxidid asphalt. The internal property change is consistent with
