【 摘 要 】

Due to the uneven gradation of asphalt mixture recovered by milling, in order to make the pavement performance of cold-mixed emulsified asphalt mixture approach or reach the standard of hot asphalt mixture, on the basis of previous experimental research, the hot-mixed AC-25 mixture was optimized and the performance of the cold-mixed emulsified asphalt mixture was optimized with the objective of the road performance achieved by the hot-mixed AC-25 mixture optimization scheme. The results of the study show that the performance of the cold-mixed cold-laid asphalt mixture after optimization can meet the road performance requirements and provide reference for engineering applications.
