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.
