摘　　要：采用AR-2000ex型动态剪切流变仪对石油沥青及改性沥青进行动态频率剪切扫描试验,利用Cross、Carreau预测模型对0.1~100 Hz频率范围内的复数剪切粘度进行零剪切粘度的拟合计算。In this paper, the dynamic frequency shear scanning test method was used to test petroleum asphalt and modified asphalt , combined with the Cross and Carreau prediction models to calculate the zero shear viscosity of the complex shear viscosity in the frequency range 0. 1-100 Hz.

关 键 词：流变仪 零剪切粘度 Cross模型 Carreau模型 混合料高温性能
