英文摘要	In order to link the chemical analysis with the pavement performance of asphalt binders, and establish a standardized and unified quantitative analysis method for Fourier transform infrared spectroscopy (FTIR), the asphalt binders of rolling thin film oven test (RTFOT) and pressure aging vessel (PAV) before and after aging were characterized by FTIR through macroscopic and microscopic methods. FTIR spectral quantitative analysis of functional change index and the complex shear modulus and phase angle of asphalt binders in dynamic shear rheometer (DSR) test under different temperature and controlled stress were conducted multivariate statistical regression analysis based on Levenberg-Macquarie method and general universal optimization algorithm. The results show that the absorption peak area of FTIR spectrum is calculated with the tangent line of the lowest point on both sides of the absorption peak, and the standard of FTIR quantitative analysis is with 2 000~650 cm-1 as the reference spectral range. The absorption peaks of 1 700 cm-1 carbonyl and 1 031 cm-1 sulfoxide increase with the increase of aging time. The complex shear modulus and phase angle of the asphalt binder after RTFOT and PAV show a multiple linear relationship with the change of chemical functional groups. © 2018, Editorial Board of Journal of Huazhong University of Science and Technology.
