摘　　要：近红外光谱主要反映C-H、O-H、N-H、S-H等有机化合物和混合物的化学键信息,沥青作为典型的有机混合物,用红外光谱可以直接对其组成结构进行定性和定量分析。近年来,红外光谱技术在路用沥青中的应用日益广泛,主要包括:沥青真伪鉴别、SBS改性沥青中SBS含量检测和沥青老化及再生机理分析三种,文章系统梳理了这三种技术的研究现状,可为红外光谱技术在路用沥青检测中的应用提供参考。Near infrared spectroscopy mainly reflects the chemical bond information of C-H,O-H,N-H,S-H and other of the organic compounds and mixtures. As a typical organic mixture,asphalt can be analyzed qualitatively and quantitatively by infrared spectroscopy. In recent years,infrared spectroscopy technology has been widely used in pavement asphalt,including: identification of authenticity of asphalt,detection of SBS content in SBS modified asphalt,and analysis of aging and regeneration mechanism of asphalt.This paper systematically erviews the research status of these three technologies and provides a reference for the application of infrared spectroscopy in road asphalt detection.
