Abstract:
The series-wound dashpot of Burgers model was modified and the model was considered as a combination of viscoelastic-plastic dashpot and Van Der Poel model. Coupled with the viscoelastic mechanics theory and damage mechanics theory, a new damage-creep model is established for asphalt mixture by introducing a strain hardening variable and a damage softening variable. A loading cycle consisting of a haversine load followed by a rest period was adopted to simulate the actual vehicle loading on asphalt pavement, and a viscoelastic-damage mechanics model was deduced for permanent deformation of asphalt mixture under repeated load. Subsequently, the proposed model was validated by the results of uniaxial permanent deformation tests of several asphalt mixtures, and the model parameters were obtained by the principle of least square. It is indicated that the proposed model can describe the whole three-phase permanent deformation of asphalt mixture comprehensively.
