为了进一步推动沥青结合料耦合老化的研究和发展,综述了国内外沥青结合料多因素耦合老化的研究现状.首先,全面分析了沥青结合料的老化影响因素和单因素老化机理;其次,介绍了已有研究中提出的不同因素耦合作用下的典型老化方法与试验条件;然后,归纳了不同因素耦合老化作用下沥青结合料宏观性能、微观结构和化学组成的多尺度变化规律;最后,综述了沥青结合料的多因素耦合老化机理.综合分析表明:现有研究中涉及的老化影响因素并不全面,已提出的沥青结合料耦合老化方法没有统一标准且试验周期过长,老化试验条件的选取存在较大差异,耦合老化作用下沥青结合料宏观性能、微观结构和化学组成等指标间未建立有效的跨尺度关联分析,沥青结合料耦合老化机理的研究并不深入,限制了耦合老化方法的发展与应用.因此,未来沥青结合料耦合老化研究中可考虑引入更全面的环境老化影响因素,提出快速高效的标准耦合老化试验方法和老化参数的选取依据,进一步探索耦合老化过程中沥青结合料化学组成、微观结构与宏观性能之间的相互作用关系,同时在耦合老化机理和老化性能验证分析等方面进一步探讨.
Review on Asphalt Binder Coupling Aging
To further promote the research and development of asphalt binder coupling aging,the research status of multi-factor coupling aging of asphalt binder at home and abroad was reviewed.Firstly,the aging factors and single factor aging mechanism of asphalt binder were analyzed comprehensively.Secondly,the typical aging methods and test conditions under the coupling with different factors proposed in previous studies were introduced.Then,the multi-scale variation of macroscopic properties,microstructure and chemical composition of asphalt binder with different coupling aging factors were summarized.Finally,the multi-factor coupling aging mechanism of asphalt binder was reviewed.The comprehensive analysis indicates that the factors affecting aging involved in the existing studies are not comprehensive.The proposed coupling aging methods for asphalt binder have no unified standard and the test period is too long.There are significant differences in the aging test conditions selection,and no effective cross-scale correlation analysis is established among the macro properties,microstructure and chemical composition of asphalt binder under coupling aging.The coupling aging mechanism research of asphalt binder is not deep,which limits the development and application of coupling aging method.Therefore,more comprehensive environmental aging factors can be considered in the future coupling aging research of asphalt binder.The rapid and efficient standard coupling aging test method and the basis for selecting aging parameters can be proposed.The interaction among chemical composition,microstructure and macro properties of asphalt binder in the coupling aging process can be explored.Simultaneously,the coupling aging mechanism and aging performance verification analysis should be further discussed.
