Abstract: Nano-silica(NS) was used as reinforcing agent to modify asphalt. Through the tests of asphalt performance, such as penetration, softening point, ductility and viscosity, Marshall test, splitting test, high temperature rutting test and semicircular bending (SCB) test, the effect of NS on the properties of asphalt and recycled aggregate asphalt concrete is studied. The results show that NS can improve the high temperature performance of asphalt, and will not have a significant impact on the viscosity, penetration and ductility of asphalt; NS can significantly improve the water stability of recycled aggregate asphalt concrete, and improve the Marshall stability, splitting tensile strength and high temperature deformation resistance, to a certain extent; NS will not significantly affect the low temperature cracking resistance of recycled aggregate asphalt concrete.
