description abstractThe modified Burgers model was considered as the series connection between a Van Der Pool model and a nonlinear dashpot to draw a conclusion that the process of damage evolution only results in a decrease in dashpot viscosity, whereas the other three elements are undamaged. A damage evolution equation was established from a statistical perspective with the distribution of the inner flaw of asphalt described by the Weibull function. The equation was then incorporated into the modified Burgers model to obtain a new viscoelastic damage model of the asphalt mixture. The creep strain, rate, and acceleration were obtained. These parameters exhibited good agreement with the three - phase creep character of the asphalt mixture. Finally, the proposed model was verified through two experimental examples. Results showed that the model considering the dashpot damage was not only simpler than the previous models, but also exhibited good agreement with the experimental result. Moreover, this method was based on a reasonable theory.
