The research was carried out to explore the effect of silica nanoparticles (NPs) on the ultraviolet aging properties of bitumen. In this study, characterization of NPs-modified Bitumen using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and ultraviolet-visible spectrophotometer were investigated. In addition, the properties of the modified bitumen considered by conventional mechanical tests. The results of this study indicated that the bitumen physical properties were influenced by silica NPs additives. Comparing oxidation degree and carbonyl in index NPs-modified bitumen samples indicates that the resistance of bitumen to ultraviolet aging is considerably improved with increase nanoparticles content, which led to the improvement in the reflection property in bitumen. Further, NPs improved the rutting resistance, viscosity, and threshold temperatures of aging bitumen, while decreasing the viscosity aging.
