| Abstract: | Diatomite is a kind of fine chemical product blended into asphalt;it can be served as a modifier of asphalt.In this article,performance experiment of diatomite modified asphalt and its mixture was studied.The results indicate that diatomite can improve performance high temperate,low temperature and anti-ageing for asphalt;diatomite modified asphalt mixture can distinctly enhance performance of high temperature,low temperature,water stability and anti-fatigue of mixture and possess excellent performance.Diatomite is a perfect modifier. |
