Abstract:The rheological properties of gussasphalt mixture was studied by means of dynamic modulus test. The analysis of the dependence of the dynamic modulus and phase angle to the temperature and frequency, and the viscosity coefficient and elastic coefficient was used to characterize the rheological properties of gussasphalt mixture. The dynamic modulus, viscosity coefficient and elastic coefficient of GA10 at different temperature were compared with EA10 and SMA10 For GA10, its viscoelastic transition temperature is 40℃,higher than that of EA10 and SMA10, its viscosity coefficient is greater than that of EA10, its elastic coefficient is less than that of EA10 Compared with SMA10, when temperature excess 30℃, its viscous coefficient is bigger, while its elastic coefficient is smaller.
