| 摘 要： | 再生沥青由于其轻组分含量较多，在老化过程中粘度变化较一般道路沥青敏感得多，无法再沿用考察一般道路沥青抗老化性能的方法。根据再生沥青的特殊性，分别采用失重系数法和，Ic(胶体不稳定指数)变化法考察了沈阳一大连、沈阳一铁岭高速公路再生沥青的抗老化性能，实验结果证明了这两种方法的可靠性。

| Abstract: | Regenerated asphalt has special performances compared with the general road asphalt in that the content of thin components in the former is higher than that in the latter, which leads to the sensitive viscosity change in aging course. The conventional method to evaluate antiaging performance of the general road asphalt can no longer be used. Two new methods including weight loss coefficient method and /c change method are used to evaluate the regenerated asphalt. |

| Keywords: | regenerated asphalt antiaging performanc weight - loss coefficient method Ic change method |
