红外光谱法在沥青结构行为表征中的应用研究现状

Research Status of Application of Infrared Spectroscopy in Asphalt Structure Behavior Characterization

沥青的微观结构分析一直是道路工作者的研究重点。红外光谱法是沥青微观结构表征的技术手段之一,国内研究者运用红外光谱法对基质沥青和改性沥青的微观结构和老化行为机理研究较多。对相关研究内容和成果进行梳理、总结,提出了现有研究中存在的问题,为后续的红外光谱法的应用扩展和沥青微观结构研究提供参考。

Microstructure analysis of asphalt has been a research focus for road workers. Infrared spectroscopy is one of technical means of asphalt mierostructure characterization. Domestic researchers often use infrared spectroscopy to make researches on microstructure and aging behavior mechanism of matrix asphalt and modified asphalt. The correlational research contents and achievement are reviewed and summarized, and problems in existing research are put forward, thus providing reference for the subsequent application extension of infrared spectroscopy and the research on the asphalt microstructure.
