Asphalt Material Aging Mechanism and Characteristics Analysis Based on Infrared Spectrum

Abstract:

The macroscopic performance of three kinds asphalt and its after aging were analyzed, and aging mechanism and characteristics were explored by. FT-IR.The results showed that the asphalt dynamic shear G*/sinδis very consistent with penetration ratio, moving wavenumber of carbonyl is a valid indicator for the evaluation of asphalt anti-aging ability.
