With the continuous increase in traffic volume, the rutting resistance of asphalt pavements has become one of the key factors affecting road service life and safety. To improve this performance, nano-SiO₂-modified asphalt has gradually gained widespread application. This study investigates the impact of nano-SiO₂ on asphalt pavement rutting resistance. Experimental results show that nano-SiO₂ can effectively enhance asphalt's high-temperature stability and significantly reduce rutting formation. Through experimental analysis of nano-SiO₂-modified asphalt with different addition rates, the study found that appropriate nano-SiO₂ addition not only improves rutting resistance but also enhances its rheological properties and thermal stability, providing new insights for the application of modified asphalt.
