摘要
通过对硅藻精土结构及物理化学特征的分析,探讨了硅藻精土增强沥青混合料高、低温和水稳定性能的机理,同时对其工程应用的经济性进行了分析,为硅藻精土作为新型改性剂的推广应用提供了理论依据和经济性参考。
Through analysing structure and physics and chemistry characteristic of purified diatomite. This paper explores the mechanisms of purified diatomite, enchancing the stability of asphalt mixture under high temperature, low temperature or with water. At the same time, the paper makes analysis on the economy of project application, providing theoretical and economical references for spreading purified diatomite as a new modifier.
