Abstract: Cationic emulsions with asphalt concentration 0.60 and 0.70 in mass were prepared respectively. Shear viscosity of the emulsions was obtained at different temperature and shear rate by using a rotating viscometer. Relation between apparent viscosity and temperature data was fitted by functional relation, and the apparent activation energy was calculated based on the apparent viscosity measuring at different temperature. The results showed that the emulsions presented a pseudo-plasticity behavior. The relationship between apparent viscosity and temperature could be described by a power law relation. Apparent activation energy of the two emulsions was 22.607 4 kJ/mol and 31.363 7 kJ/mol, respectively.

摘要： 制备了沥青质量分数分别为0. 6 0和0. 7 0的阳离子乳化沥青试样。采用旋转黏度计测定了不同温度 和剪切速率下试样的表观黏度, 拟合了试样的表观黏度与温度的关系, 计算了试样流动的表观活化能。结果表明, 在试验条件下, 乳化沥青试样为假塑性流体, 表观黏度与温度的关系可由幂律关系描述, 表观活化能分别为2 2. 6 0 74 k J /m o l和3 1. 3 6 37k J /m o l 。
