摘　　要：基于对改性沥青分离机理的理论分析,采用热存储稳定性离析试验和扫描电镜观测的方法,对不同掺量以及不同种类硅藻土改性沥青进行了相容性测试。通过对硅藻土改性沥青的相容性研究,证明硅藻土改性剂数量和微观结构上的差别造成了对沥青吸附的差别,表现为相容性的不同,并得出离析随时间变化的规律。The paper based on the academic analyse of modified-asphalt＇s separate mechanics, tests diatomite, different content diatomite-modified-asphah and different varieties diatomite-modified-asphalt by separate test and stereoscan. And it illuminates that difference of diatomite＇ s quantity and microstructure will bring on the different asphalt＇ s adsorbency, demonstrate the different consistency of diatomite-modified-asphah,and gained the varied regularity of separation with time. The conclusion of this paper offers the academic gist for the actual application of diatomite-modified-asphah.
