| Abstract: | The mechanisms of photooxidation aging of asphalt are described in this paper. The changes of apparent viscosity of four road asphalt samples after the photooxidation aging were studied and a first order photooxidation aging kinetic model based on apparent viscosity data was set up to investigate the anti-aging performance of four road asphalts, get to the kinetic parameter. |
