Road recycling technology is gradually becoming a research focus in road construction due to natural resource shortages. It is therefore necessary to carry out deep and extensive analysis of the huge amount of publications in the research area of recycling technology in road construction. Based on three databases (Web of Science, Compendex and Scopus) and VOSviewer visualization software, this study conducts a bibliometric analysis of the literature in the field of recycled construction materials in pavement engineering. The global research publications were reviewed to quantitatively identify the literature characteristics. A number of publications, document types, research areas and keywords were used to achieve the general statistics of this reviewed literature. H-index, publication number and citations per publication were used to evaluate the academic contributions by country, institution and journal. The results show that the most productive country and institution for publications are the USA and Chang'an University from China, respectively, followed by China and Wuhan University of Technology. In recent years, researchers have generally paid attention to two main approaches: the application of rubber modified asphalt and the performance enhancement of recycled pavement.
由于自然资源短缺，道路再生技术正逐渐成为道路建设领域的研究热点。因此，有必要对道路建设再生技术研究领域的大量出版物进行深入广泛的分析。基于三个数据库（Web of Science、Compendex和Scopus）以及VOSviewer可视化软件，本研究对路面工程中再生建筑材料领域的文献进行了文献计量分析。对全球研究出版物进行了综述，以定量识别文献特征。使用了一些出版物、文献类型、研究领域和关键词来实现对这些综述文献的总体统计。采用H指数、出版物数量和每篇出版物的引用次数来评估国家、机构和期刊的学术贡献。结果表明，出版物产出最多的国家和机构分别是美国和中国的长安大学，其次是中国和武汉理工大学。近年来，研究人员普遍关注两种主要方法：橡胶改性沥青的应用和再生路面性能的提升。
