摘　　要：采用22个沥青试样在60~180℃进行了黏温性拟合,发现拟合方程的斜率(K)和截距(B)间几乎完全呈线性关系,将不同沥青试样的Saal方程组关联,可得到迄今为止最简单的黏温数学模型即ZXY-B和ZXY-K模型。通过ZXY-B模型预测值与实测值间相对误差和标准方法精密度对比研究发现,模型预测值的准确性、有效性与石油沥青的软硬程度、基础温度的选择密切相关;采用ZXY-B或ZXY-K方程以135℃为基准温度预测的数据最准确;只需要一个温度下的黏度数据就可准确、有效预测60~180℃温度范围内其他温度下的黏度数据;在人力、设备、时间、经济等方面比Saal方程更有优势。22 asphalt samples were used to analyze the viscosity-temperature characteristics over a range of 60-180℃.It is found that the slope(K)and intercept(B)of the fitting equation are almost linear.This linearity allows for the association of the different asphalt samples with the Saal equation,leading to the development of the simplest viscosity-temperature mathematical models to date:the ZXY-B and ZXY-K models.A comparative analysis of the relative errors between the predicted values from the ZXY-B model and the measured values,as well as the precision of the standard method,reveals that the accuracy and effectiveness of the model’s predictions are closely related to the selection of the soft and hard grades of petroleum asphalt and the base temperature.Specifically,using the ZXY-B or ZXY-K equations with a base temperature of 135℃yields the most accurate predictions.Furthermore,the mathematical model requires viscosity data at only one temperature to accurately and effectively predict the viscosity data at other temperatures within the range of 60-180℃.It has more advantages than Saal equation in terms of manpower,equipment,time,and cost.
