This study looked at the state-of-the-art present knowledge base and trends in the area of using rejuvenators in reclaimed asphalt pavement (RAP) by systemic analysis and visualisation using VOSviewer and Scopus analyser; a total of 1872 studies were mined from the Scopus database for the purpose of this study. This quantitative approach to the review of literature removes author bias. The study was able to identify keywords and their cluster groups making up of core research domains ((1) asphalt binder composition and properties, (2) reclaimed asphalt mixtures (recycling), (3) reclaimed asphalt performance characteristics, (4) reclaimed asphalt sustainability, (5) rejuvenating agents and their performance, and (6) area of application). The study was able to identify the top authors; their document counts and citations; the most influential journals, institutions, and countries leading the way in the research domain; and the link between these authors and keywords within the existing body of literature in the research area. This study will help policymakers in identifying the main research themes and possible area of investments for further research in RAP. This study will also be a valuable compendium to researchers who intend to broaden the scope of the research area.
本研究通过使用VOSviewer和Scopus分析器进行系统分析和可视化，审视了再生沥青路面（RAP）中使用再生剂领域的当前技术水平、现有知识库及发展趋势；为了本研究的目的，从Scopus数据库中挖掘了总共1872项研究。这种对文献进行综述的定量方法消除了作者偏见。该研究能够识别构成核心研究领域的关键词及其聚类组（(1)沥青结合料组成与性能，(2)再生沥青混合料（回收利用），(3)再生沥青性能特征，(4)再生沥青可持续性，(5)再生剂及其性能，以及(6)应用领域）。该研究能够识别顶尖作者、他们的文献数量和引用次数；在该研究领域处于领先地位的最具影响力的期刊、机构和国家；以及这些作者与该研究领域现有文献中的关键词之间的联系。本研究将有助于政策制定者确定主要研究主题以及在RAP方面进一步研究的可能投资领域。对于打算拓宽研究领域范围的研究人员来说，本研究也将是一份有价值的汇编资料。
