摘　　要：根据研究需要采取DSR仪器并将镇海70#基质沥青作为研究对象,对其进行动态剪切实验,进而得到相关的动态频率谱。按照Han曲线的研究内容对该沥青做相关研究,该沥青在试验条件内为非均相体。进而再研究沥青的相关路用性能,分析表明0℃之前该沥青的高温性能良好,疲劳性能很差。This article adopts the DSR instrument according to the need of research and makes Zhenhai 70# asphalt as the research object,the dynamic shear test was done on it,and then the associated dynamic frequency spectrum was got. According to the research content of Han curve,the asphalt was heterogeneous in the test conditions; and the related road performance of asphalt is analyzed. The results show that the asphalt has good performance at high temperature and poor fatigue performance before 0 ℃.

关 键 词：频率谱 Han曲线 非均相体
