Low-temperature characteristics and microstructure of asphalt under complex aging conditions

Shuyan Zhang et al.

Summary: The study found that SBS modified asphalt has better plastic deformation ability and anti-aging ability, but a lower critical temperature compared to 90# asphalt. As the temperature dropped, the relaxation time gradually increased, and the dissipation energy ratio declined. Bee-shaped structures were observed on the surface of the asphalt, with an increase in aging degree leading to a decrease in the number of bee-shaped structures and a more dispersed distribution.
