Study on aging performance of modified asphalt binders based on characteristic peaks and molecular weights
Construction and Building Materials(2019)
Abstract
•The absorption peak of the sulfoxide group is apparent after long-term aging.•The stabilizer can improve the high temperature stability of asphalt effectively.•The furfural extract oil can crosslink the modifiers to form a network structure.•Degradation and polymerization occur during thermal aging of modified asphalt.
