Asphalt is a common building material for roads because it is a crucial adhesive. Asphalt ages through a series of aging processes, including volatilization, oxidation, and polymerization, which cause it to become hard and brittle under the influence of high temperature, oxygen, water, ultraviolet rays, and other factors. Pavement damage such as thermal crack, fatigue crack, and cohesion failure accelerate with asphalt aging, significantly shortening the pavement's service life. During the asphalt aging process, the most important reaction is oxidation. To improve asphalt's resistance to aging, it is essential to comprehend the oxidation reaction mechanism.
