EXAMINATION OF APPLICATION CONDITIONS FOR VARIOUS INFRARED SPECTROSCOPIC ANALYSIS METHODS FOR ASPHALT MIXTURES
The effectiveness of infrared spectroscopic analysis has been reported as a method for examining the deterioration of asphalt and the presence of modifiers. In recent years, the miniaturization of infrared spectroscopic analyzers has progressed, and handheld types are also available. So, they are expected to be used in the field. Infrared spectroscopy has measurement methods other than total internal reflection absorption measurement (ATR), and it is considered possible to examine asphalt mixtures non-destructively by selecting a method suitable for the target. In this investigation, the authors focused on the diffuse reflection method and the photoacoustic method, performed infrared spectroscopic analysis of asphalt binders and asphalt mixtures, and examined the application conditions of these measurement methods. As a result, the measurement conditions and application range when applied to asphalt mixtures were clarified.
