| 摘 要： | 在查阅国内外相关资料的基础上,综述了沥青老化的主要机理。认为,沥青的化学组分变化是导致沥青＂变硬＂的外因,然而轻质组分的挥发和被吸收、各组分的氧化、聚合、沥青质的团聚以及改性剂的裂解才是导致组分变化和沥青老化的真正内因。

| Abstract: | Based on the review of the relative literatures,the asphalt aging mechanisms were summarized and discussed.Chemical components changes were the external causes which leaded to asphalt hardening. But,The lighter components evaporation and being selective absorbed by stone,oxidation reaction,polymerization, asphaltene reuniting,and modifier degradation were the real internal causes which leaded to chemical components changes and asphalt ageing. |
