摘　　要：分析了沥青性质、沥青混凝土级配与沥青含量等内部因素对沥青混凝土疲劳损伤自愈合能力的影响,提出可通过优化沥青混凝土组成设计实现沥青混凝土自愈合能力主动增强。总结了基于能量供给和物质补充原理的沥青混凝土自愈合能力被动增强技术,重点分析了加热和掺加含有界面粘合剂胶囊两种方法的技术可行性和存在的问题。The effect of intrinsic factors of asphalt concrete, such as asphalt properties, aggregate gradation and asphalt content on self- healing ability of asphalt concrete were analyzed. A form of design philosophy which was based on optimizing asphaIt concrete composition design was discussed in the objective of enhancing the self healing behavior actively. According to principal theory of bionics, characteristics of two kinds of passive enhancement technology, energy supply based technology and substance filling based technology were summarized. The paper was emphasized on the technical feasibility and existent problems of heating method and Microcapsule method which were in the form of thermal treatment and filled with adhesive binders respectively.
