摘要
研究了以辽河油田生产的稠油为基质沥青自制的两种沥青老化后软化点的变化,以软化点为参数建立了沥青一级老化动力学模型。并用该动力学模型对这两种沥青的抗老化性能进行了研究,求得了动力学参数。实验结果表明,这两种沥青老化后软化点均升高,AH70沥青抗老化性能优于AH90沥青,以软化点为参数建立的沥青老化动力学模型较好地表征了沥青老化过程,为研究沥青老化提供了一种简便可行的分析方法。
The changes of softening point of two road asphalt samples were studied and a first order aging kinetic model based on softening point data was set up to investigate the anti-aging performance of two industrial road asphalts, AH-70 and AH-90. The results showed that the softening point of asphalt increased after aging; the anti-aging performance of AH-70 asphalt was better than that of AH-90 asphalt; the aging process of road asphalt could be expressed by said aging kinetic model, and kinetic parameters were obtained. The proposed aging kinetic model offered a simple and feasible way to study the aging of road asphalt.
