AB - Application and performance optimization of phase change energy storage materials for road asphalt mixtures are investigated. A thermal-mechanical coupling prediction algorithm (HTCPPO) is proposed. It was found that the phase change temperature was 25−40∘C, average potential heat was 180J/g, and 15∘C temperature was 1.2W/mK. After the algorithm simulation, the performance is optimal when the dosage is 10%. The internal temperature change decreases by 35% when the ambient temperature changes by 10∘C, the compressive strength reaches 12MPa (an increase of 20%), and the Marshall stability increases by 25% to 8kN. The algorithm achieves precise optimization and provides a new technical path for road engineering.
