21世纪以来中国RAP材料历程——基于CiteSpace的定量分析

History of RAP Materials in China Since the 21st Century: Quantitative Analysis Based on CiteSpace

为探究21世纪以来中国RAP材料的研究现状,并为后续阶段的研究提供参考方向,本文以中国知网2000-2021年共1875篇文献为研究样本,借助CiteSpace文献计量软件,依次以作者和关键词为节点,制作RAP材料相关的知识可视化图谱,并从研究现状、焦点及演进趋势多维度对其研究进行分析和总结。研究表明:自2007年,RAP的研究总体上呈稳定上升趋势;发文作者的分布较为分散,虽有一定的网状结构,但未形成明显聚类。在后续研究应着眼于RAP材料变异性、路用性能等,为实现RAP材料多元化高价值应用提供理论支撑和实践参考。

In order to explore the research status of rap materials in China since the 21st century and provide reference direction for subsequent research,this paper takes a total of 1875 documents of CNKI from 2000 to 2021 as research samples,with the help of CiteSpace document metrology software,and takes the author and keywords as nodes in turn,makes a visual map of knowledge related to rap materials,and analyzes and summarizes its research from the multidimensional aspects of research status,focus and evolution trend.The research shows that since 2007,rap research has generally shown a stable upward trend;The distribution of authors is relatively scattered,although there is a certain network structure,but there is no obvious clustering.In the follow-up study,we should focus on the variability and road performance of rap materials,so as to provide theoretical support and practical reference for realizing the diversified and high-value applications of rap materials.
