[0002] Pavement defects not only affect the appearance of roads, but may also pose a threat to the safe driving of vehicles. In order to improve the strength of highway pavements, rubber, resin, fiber, high molecular polymer or other fillers are often used as modifiers to improve the high temperature stability, low temperature crack resistance and aging resistance of asphalt and its mixture. In the process of asphalt modification, shearing machines are often used to blend the modifier with asphalt. The mechanism of modified asphalt is to make the modifier evenly distributed in the asphalt to form a spatial network structure with a certain strength. The excellent performance of modified asphalt has been confirmed in many engineering practices.
