Abstract :
The external viscous component of Burgers model was improved based on the creep test data of asphalt mixture. And the constitutive equations of the modified Burgers model were obtained. This modified Burgers model was verified with the dynamic indirect tensile test. The parameters of modified model has been identified by nonlinear fitting of the indirect tensile strain curves. It proved that the modified Burgers model can be used to characterize the all creep stages of asphalt concrete.
