Abstract:At present, the maintenance costs of expressway are mainly from the tolls collected. The expressway operating units in the cost control of "too tight" awareness is still not strong. The degree of refinement of maintenance engineering cost control is low. The existing problems in the special engineering cost management of the expressway maintenance are analyzed. Based on the lack of foresight, lack of management system and lack of post-evaluation of maintenance engineering cost management, the key points of the whole process cost management of the maintenance project in the project preparation stage, the implementation stage and the completion stage are summarized, which provides reference for the engineering cost management of the expressway maintenance.
