Abstract: Combined with the maintenance and management requirements of electromechanical equipment in the operation phase, this paper classifies and codes the electromechanical equipment and its information based on the current local standards, aiming to aggregate data on expressway construction, management and maintenance, and defines the information content of electromechanical equipment that should be submitted to the operation phase during the construction phase. A standard system of data aggregation for the whole life cycle of expressways in operation is established. The research results can provide reference for the revision of current local standards and other similar highway engineering operation and maintenance management.
