沥青混合料自愈合行为被动增强技术研究

Research on passive enhancement technique of self-healing behaviors of asphalt mixture

阐述了基于能量补偿和物质补偿原理的沥青混合料自愈合能力被动增强技术的可能性和存在的问题,同时对以加热为代表的被动自愈合增强技术进行了前期的探索研究,通过具有90%保证率的疲劳寿命的检验结果表明,以加热方式为代表的增强技术能显著增加沥青混合料的自愈合行为,延长疲劳寿命。

The paper describes possibility and problems of the passive enhancement technique of self-healing behaviors of asphalt mixture based on the energy compensation and material compensation, the paper undertakes the exploration in the earlier phase of the passive self-healing en hancement technique represented by the heat, and proves by the test result of the fatigue lifespan with 90% assurance rate that the enhancement technique represented by the heat can increate the self-healing behavior of the asphalt mixture, so as to prolong the fatigue lifespan.
