沥青与填料的相互作用对沥青胶浆及混合料的性能有重要影响，温度和荷载频率影响沥青与填料的相互作用能力。本文选用两种基质沥青结合料和三种填料，制备了不同填料体积分数的沥青胶浆，测定了沥青胶浆的动态剪切流变性能。首先分析了基质沥青结合料和砂胶的线粘弹性范围。然后采用K-B-G模型评价和分析了温度和加载频率对沥青与填料相互作用能力的影响。结果表明：在温度和加载频率不变的情况下，基质沥青结合料的线粘弹性范围随加载频率的增加而减小，随温度的增加而增大;沥青胶浆的线粘弹性范围随填料体积分数的增加而减小; K-B-G曲线随温度的增加呈指数形式增加，随加载频率的增加而线性减小。采用灰色关联法对温度和加载频率进行了显著性分析，发现温度的影响比加载频率更深。
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 theK-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.
