This paper researches the consistency by eduction and SEM test, analyses the modality and mechanism of diatomite in asphalt by SEM, IR and DSC microcosmic test, and considers that diatomite forms a steady and symmetrical mixed system in asphalt.

• 并通过扫描电镜、红外光谱和DSC差热分析等微观试验对硅藻土在沥青中的存在形态、作用机理进行分析,认为硅藻土掺加到沥青中形成了稳定、均匀的共混体系。
