摘　　要：为提高对再生剂在老化沥青中扩散机理的了解,综述了近年来国内外对再生剂扩散研究的现状。从宏观性能、微观结构和化学组分三个尺度,概述了再生剂扩散的研究成果,并对各尺度表征手段的优点和不足进行了分析,展望了再生剂扩散行为的未来研究方向。In order to improve the understanding of the diffusion mechanism of rejuvenators in aged asphalt,this paper reviews the current research status of rejuvenator diffusion both domestically and internationally in recent years.This review summarizes the research findings on the diffusion of rejuvenators from three scales:macroscopic performance,microscopic structure,and chemical composition.The advantages and disadvantages of characterization methods at each scale are analyzed,and future research directions on the diffusion behavior of rejuvenators are discussed.
