Paper Title:
Study on Anti-Ultraviolet Radiation Aging Property of TiO2 Modified Asphalt
  Abstract

In order to decrease the disadvantageous effect of ultraviolet light to asphalt, nano-scaled TiO2 was selected as modifier to modify asphalt. The photooxidation properties of the modified asphalt were examined in a home-made ultraviolet radiation environment box. By comparing the before and after performance indexes of asphalt, the anti-photooxidation aging property of modified asphalt and the blank asphalt were studied. And the results showed that the sample of 5% TiO2 modified asphalt possesses more stable ductility and smaller softening point changing ratio.TiO2 doping can actively enhance the photooxidation properties of asphalt and TiO2 modified asphalt is capable of resisting photooxidation aging.
