The high temperature rheological properties of asphalt is an important basis for selecting asphalt in practical engineering. It is tested by using a dynamic shear rheometer (DSR). Through temperature scanning software, a strain-controlled mode can be adopted, so, the frequency was controlled at 10 rad/s, the temperature scanning range was 30–90 °C, the heating rate was 2 °C/min, the plate diameter was 25 mm, and the spacing was 1 mm. During the testing process, a lower plate was fixed, and an
