    摘要:

    研究了符合GB15180-94重交通道路沥青标准的彩色道路沥青的老化过程。结果表明:提出的两种老化动力学模型能够很好地描述两种彩色道路沥青的老化速率。彩色沥青老化后,沥青质含母增加,胶质、芳香酚、饱和酚含量减少。沥青胶体的原有平衡体系遭到破坏,导致沥青使用性能变坏。彩色沥青老化过程中,沥青胶体不稳定指数(Ie)对沥青老化条件很敏感,随老化温度的升高和老化时间的延长而增加;粘度随老化时间的延长近似呈指数关系增加,所以可以用胶体不稳定指数和老化指数来评价彩色沥青的老化性能。

    Abstract:

    Aging processes of colored paving asphalt conforming to GB 15180-94 standard were studied. The results show that the presented dynamics models can be used to describe the aging velocity of the two kinds of colored paving asphalt perfectly. After aging, asphaltene content increased, resins and aromatics content decreased as well as saturate content. As a result, the original colloidal structure of colored paving asphalt is destroyed, which deteriorates the colored paving performance. During aging, Gastel index (Ie) which is sensible to aging condition decreased with increase of aging temperature and aging time. As the same time, the exponential relationship between the change of viscosity and aging time was discovered. Both the gastel index and the aging index can be used to evaluate the aging resistance of the colored paving asphalt.
