As an effective means of infrastructure digitization, BIM (Building Information Modeling) can not only provide an effective 3D digital information model in the lifecycle of highways, but also provide a good means of data organization and management. Through BIM model, information of different stages can be stored and connected, decentralized and fragmented data of planning stage, design stage, construction stage, operation and maintenance stage can be centralized and integrated, so as to realize queryable and traceable data in the lifecycle.As a surreal concept,digital twins,combined with current advanced technology,has great potential for application in the lifecycle of highways.
