According to the actual requirements of the project, a mix proportion optimization plan for high-durability asphalt pavement materials is formulated, and its road performance is verified through tests such as freeze-thaw resistance, low-temperature crack resistance, high-temperature stability, and aging resistance. Practical applications indicate that the determined mix proportion optimization plan for high-durability asphalt pavement materials is suitable under extreme climatic conditions and aligns with the design expectations of this research, providing a reference for subsequent similar projects.
