中文摘要：

采用动态剪切流变仪和布氏旋转粘度计，对不同粉胶比下的TPS高粘改性沥青胶浆流变特性进行研究，分析了粉胶比和试验温度对相位角、复数剪切模量、车辙因子、疲劳因子以及布氏粘度的影响．试验结果表明：在各粉胶比下沥青胶浆的复数剪切模量、车辙因子和疲劳因子都随温度的升高而减小；温度一定时，随粉胶比的增大，车辙因子显著增大，疲劳因子逐渐减小，当粉胶比大于1．4时，车辙因子的增长幅度明显减小；当粉胶比小于1．2时，粘度随温度的增长速率较小，粉胶比大于1．2时粘度随温度升高急剧增大，沥青胶浆的感温性随温度升高而增大．综合各指标来看，粉胶比在1．2-1．4之间时，TPS高粘改性沥青胶浆流变性能优越．

英文摘要：

The properties of different dust-to-binder Ratio of TPS high viscosity modified asphalt mortar were researched comparatively with Dynamic Shear Rheometer（DSR） and Brookfield Viscometer. The variation of phase angle, complex shear modulus, rutting factor, fatigue factor and Brookfield viscosity with Dust-to-Binder Ratio and test temperature were analyzed. The results were as follows： the complex shear modulus, rutting factor and fatigue factor of all asphalt mortar decreased as the temperature rose up; While the temperature was constant, with the Dust-to-Binder Ratio increasing, the rut factor increased significantly and the fatigue factor decreased gradually and when the Dust-to-Binder Ratio was greater than 1.4, the growth rate of rutting factor reduced significantly; When the Dust-to-Binder Ratio was less than 1.2, the growth rate of viscosity with temperature was smaller, and when the Dust-to-Binder Ratio was greater than 1.2, the viscosity increased rapidly with the rising of temperature. The temperature susceptibility of asphalt mortar increased as temperature rise. All factors considered, when the Dust-to-Binder Ratio was between 1.2 and 1.4, the rheological properties of asphalt mortar with high viscosity of TPS are superior.
