Experimental Research on the Performance of Modified Asphalt of Diatomaceous Earth
The effects of different asphalt grades,mixing amount of diatomaceous earth and material characteristics on the performance of modified asphalt are analyzed,so as to explore the improvement effect of silane coupling agent on the modified asphalt of diatomaceous earth.The research shows that:the right amount of diatomaceous earth can improve the performance of asphalt and inhibit aging,and it still meets the requirements of the relevant specifications although the ductility is affected.Diatomaceous earth modifiers with high specific surface area and high SiO2 content have a significant effect on improving the performance of asphalt.The aging test shows that,diatomaceous earth can significantly inhibit the aging of asphalt,and the single mixing effect is the best.In general,diatomaceous earth is suitable for improving the quality of asphalt and prolonging the life of pavement.
