dc.description.abstract
In current pavement engineering practice, simply and effectively characterizing elemental changes in asphalt is conducive to optimizing chemo-mechanical performance, diagnosing aging conditions, and guiding rejuvenation. The study proposed an improved Fourier-transform infrared spectroscopy (FTIR) method to improve elemental quantification capability of attenuated total reflectance (ATR) mode by integrating transmission (TR) mode. The results showed that TR- and ATR-FTIR have promising analytical performance in quantifying alkyl content and semi-quantifying functional group content, respectively. The spectral indexes of the improved FTIR method shows promising correlations with the element changes, namely atomic H/C ratio and heteroatom content (S, O, and N), with R2 values of 0.97, 0.45, 0.78, and 0.75, respectively. Moreover, K-nearest neighbor regression (KNR) prediction achieved R2 of 0.99, 0.93, 0.84, and 0.92, respectively. The findings suggested quantitative effect and online testing potential for elemental analysis of asphalt.
