沥青路面红外光谱快速检测技术研究

Research on Infrared Spectrum Rapid Detection Technology of Asphalt Pavement

从基质沥青质量、SBS改性剂掺量的快速检测方法出发,结合工程实例探究了红外光谱技术下的沥青路面快速检测。研究结果表明:在规定的试验要求下,当基质沥青的实测谱图、标准谱图之间的相似度系数大于99.00%且两次独立重复试验结果的偏差小于5.0%时即可认定为符合要求。

Based on the rapid detection method of base asphalt quality and SBS modifier content, combined with engineering examples, the rapid detection of asphalt pavement by infrared spectroscopy technology is explored. The results show that: under the specified test requirements, when the similarity coefficient between the measured spectrogram and the standard spectrogram is greater than 99.00% and the deviation between the two independent repeated test results is less than 5.0%, the matrix asphalt can be considered as meeting the requirements.
