Abstract:Automobile proving grounds play a vital role in multiple stages of research and development, production and sale of automobile. Maintaining the stable testing functions of special roads in automobile proving grounds is crucial for the operation of automobile proving grounds. To enhance the operation and maintenance management level of the special roads in the automobile proving grounds, the maintenance management methods of special roads are discussed. By sorting out the development trajectory of automobile proving grounds, the functional essentials of special roads are analyzed. Combined with the automobile testing requirements and the characteristics of special roads, an evaluation indicator system is proposed. A maintenance decision-making model based on various detection technologies is built, which can maintain and enhance the pavement performance and testing functions of special roads, and also optimize the resource allocation. Based on IT technology, a digital and intelligent management system is established to cover the business handling, data analysis and asset management. Combined with BIM + GIS technologies, the refined classification management of special road pavements is achieved.
