摘要
荧光示踪法因能够通过荧光示踪剂标记沥青,帮助研究人员更加直观地观测到沥青的微观结构,从而广泛应用于沥青材料研究中。首先简要介绍了目前广泛应用的4类示踪剂的特点及其应用的主要领域;在此基础上,重点概述了荧光示踪法的原理及在沥青材料研究中常用的荧光示踪剂;接着总结了当下沥青荧光显微试样的制备方法并分析了各种方法的优点与不足;最后综述了荧光示踪法在新-旧沥青融合、沥青改性机理等方向的应用并提出了新型荧光示踪剂使用设想。该研究成果可为荧光示踪法在精确量化分析沥青微观性能方向提供新的研究思路。
Fluorescent tracer has been widely used in the study of asphalt materials because it can label bitumen with fluorescent tracers and help researchers to observe the microstructure of bitumen more visually.Firstly,the characteristics of the four types of tracers that are widely used and the main application fields were introduced;Then,the principle of fluorescence tracer and the fluorescent tracer commonly used in the study of asphalt materials were key overviewed.The current preparing methods of asphalt fluorescence microscopic samples were summarized to analyze the advantages and disadvantages of various methods;Finally,the application of fluorescence tracer method in the fields of fusion between virgin and aged asphalt,asphalt modification mechanism was reviewed,and the new fluorescent tracer was proposed.The results propose a new research idea for the fluorescence tracer method in the field of accurate quantitative analysis of the microscopic properties of asphalt.
