摘要
沥青混凝土具有自愈合能力已经得到证实,并且沥青混凝土自愈合行为是研究沥青混凝土疲劳性能、建立室内外疲劳寿命关系、增强抗疲劳能力的基础。根据近20a来国内外有关沥青混凝土疲劳损伤自愈合行为相关报道,就沥青混凝土自愈合行为机理、自愈合行为评价指标及其测试方法进行了总结。
The healing behavior of asphalt concrete has been confirmed.It has been fully aware that the healing behavior of asphalt concrete is of great importance for researching the fatigue performance and mechanism, establishing fatigue life behavior between laboratory and reality,enhancing fatigue resistance.Self-healing has attracted increasing research interests,the present article reviews state - of - art of the achievements on the topic in recent 20 years,and a summary of the healing behavior mechanism,characterization parameters and test methods are given.
