摘要：

The asphalt and filler interaction plays a significant role on the performances of asphalt mastics and mixtures, and the asphalt and filler interaction ability is affected by the temperature and loading frequency. In this paper, two kinds of matrix asphalt binders and three kinds of fillers were selected to prepare asphalt mastic with different filler volume fractions, and the dynamic shear rheological properties of asphalt mastics were measured. The linear viscoelastic range of matrix asphalt binder and mastic was analyzed firstly. Then the K-B-G* model was used to evaluate and analyze the influence of temperature and loading frequency on asphalt and filler interaction ability. The results show that the linear viscoelastic range of matrix asphalt binders decreases with the loading frequency increasing and increases with the temperature increasing, the linear viscoelastic range of asphalt mastics decreases with the filler volume fraction increasing at the constant temperature and loading frequency. K-B-G* exponentially increases with the temperature increasing and linearly decreases with the loading frequency increasing. The significance analysis of temperature and loading frequency was conducted by using grey correlated method, and finding that the temperature has deeper influence than loading frequency.
