【 摘 要 】

In order to study the rheological and rotary viscosity characteristics of asphalt mortar with high viscosity containing different asphalt and filler, the component, filler-bitumen ratio and temperature are considered. The results show that among these factors, viscosity and specific surface area are the main factors that influence the ability of resistance to high temperature deformation. The temperature sensitivity and G∗/sinδ increase with increasing filler-bitumen ratio.The growth rate changes corresponding to the filler-bitumen ratio of 1.2. A good exponential relationship exists between G∗/sinδ and Brookfield rotary viscosity at 135°C and 150°C. Thus, the results of Brookfield rotary viscosity can be used to estimate the influence of filler-bitumen ratio to asphalt mortar characteristics at high temperature instead of filler-bitumen ratio to asphalt mortar characteristics at high temperature instead of G∗/sinδ.
