Improve the understanding of the importance of preventive maintenance
We should further improve the understanding of the importance of preventive maintenance and raise preventive maintenance to the level of highway asset protection and road protection. At present, leaders at all levels and maintenance departments do not fully understand the significance of preventive maintenance of asphalt pavement. We should deepen our understanding of the important role of preventive maintenance and improve the strategic awareness, initiative and creativity of preventive maintenance. At the same time, the maintenance department should strengthen communication and exchanges with transportation authorities and financial management departments at all levels, so that departments at all levels understand the importance and necessity of preventive maintenance and create conditions for the implementation of preventive maintenance and funding sources. At the same time, it is very necessary to add preventive maintenance to the classification of maintenance projects, which will help the management of leaders at all levels and the implementation of preventive maintenance.
Improve the decision-making and planning of preventive maintenance
According to the decision-making and planning process, reasonably arrange the preventive maintenance of asphalt concrete pavement structure to ensure the safe and stable operation of highway projects throughout the life cycle, and reduce production costs while providing high-quality traffic services. Therefore, the key to preventive maintenance of asphalt concrete pavement structure lies in establishing a scientific decision-making and planning mechanism. The Ministry of Transport proposed in the “13th Five-Year Plan for Highway Maintenance Management Development” that the average annual mileage of preventive maintenance for expressways should not be less than 8%, and that for ordinary national and provincial roads should not be less than 5%. In the actual application process, local governments should also actively summarize experience and propose different preventive maintenance ratios based on the specific conditions of different regions.
