An IR and Pyrolysis-Gas Chromatography/Mass Spectrometry Microscopic Analysis on the Asphalt Aging Mechanism

摘要

In order to study the relationships between the asphalt microstructure and its properties after aging, traditional testing, IR, and Py-GC/MS was conducted on base and SBS modified asphalt. Based on the characterization of PAV aging comparisons, the effects of RTFOT aging on asphaltperformance are not particularly large. The anti-aging performance of SBS ESSO is better than base asphalt. The IR and Py-GC/MS are combined. They complement each other to facilitate the analysis of the asphalt aging microstructure.
