The changes of penetration, softeningpoint and ductility of asphalt during aging proved that the kinetic model is reliable.
同时，老化过程中，沥青针入度、软化点及延度的变化进一步证明了所得动力学模型是可靠的。

The first order aging kinetic model has been put forward successfully based on softeningpoint, which offered an available and convenient method for studying the asphalt aging behavior.
以软化点为参数建立了沥青一级老化动力学模型，为研究沥青抗老化性能提供了一种简便可行的分析方法。
