摘要：研究了两种道路沥青老化动力学，计算得到有关动力学参数，揭示了沥青组成结构与其老化性能之间的关系。结果表明道路沥青老化属于一级动力学反应。较低芳香度和较长烷基侧链的沥青，在受热条件下其烷基侧链易于断裂而形成自由基，引发了氧化反应，因而其抗老化性能较差。
The kinetics of two paving asphalt aging has been studied. Some kinetic parameters were calculated and the relationship between the composition and the structure of the paving asphalt and its aging performances were revealed. It shows that the aging of the paving asphalt is a first order reaction. The alkyl side chain was easy to break and form free radical for the asphalt with lower aromaticity and longer alkyl side chain, this would cause the oxidation reactions, the aging resistant performance of this asphalt was weak.
