By measuring viscosity-temperature characteristics, the performance and stability of modified bitumen can be predicted. According to the research results in the reference information, the viscositytemperature characteristics of modified bitumen are different from those of ordinary bitumen, and the viscosity depends on temperature and shear rate differently.

Viscosity is an important parameter to measure the viscosity of bitumen material, which is closely related to the mechanical behavior of bitumen pavement. Therefore, by measuring the viscosity and temperature characteristics of modified bitumen, the viscosity changes with temperature and shear rate can be understood, so as to predict the performance and stability of modified bitumen under different temperature and shear conditions.

This is of great significance for reasonable selection of construction temperature of modified bitumen and prevention of rutting on pavement. According to the research, the properties and stability of modified bitumen can be predicted by measuring the viscosity and temperature characteristics, which has guiding significance for the application and engineering practice of modified bitumen.
