摘要
通过探讨硅藻土在沥青及沥青混合料中的改性机理,结合高温稳定性试验,研究硅藻土改性沥青混合料的高温性能,分析不同掺量条件下硅藻土沥青混合料路用性能改善状况。研究表明:硅藻土作为沥青改性剂,抗车辙能力强,能较好地提升沥青混合料的高温稳定性。
Through discussing the mechanism of diatomite modifying asphalt and its mixture and combining with the test of high temperature stability, the high temperature performance of diatomite-modified asphalt mixture is studied and the improvement of road performance with different proportion of such mixture is analyzed. The research shows that diatomite, could improve the high temperature stability of as asphalt modifier, has strong ability of rutting resistance and asphalt mixture well.
