Minor maintenance and upkeep of highways is an important step in maintaining their good condition, which is of great significance in ensuring traffic safety, improving road service life, and improving service levels. The aim of this study is to analyse the cost of minor repairs and maintenance of ordinary national and provincial trunk highways, and to provide decision-making support and resource allocation suggestions for highway management departments. Through detailed statistical analysis of daily maintenance costs and minor repair project expenses, the impact of different types, traffic flow, and geographical locations of highways on maintenance costs was revealed. Research has found that road maintenance, bridge maintenance, and tunnel maintenance are the most expensive projects, while preventive maintenance and the promotion of new technologies and materials can effectively reduce maintenance costs. Therefore, this article proposes cost control measures such as constructing a cost allocation system, implementing dynamic adjustment strategies, strengthening preventive maintenance efforts, and promoting new technologies and materials, which can help highway management departments to have a more comprehensive understanding of the composition and distribution of highway minor maintenance costs, optimize maintenance resource allocation, improve maintenance efficiency and quality, and provide useful references for the sustainable development of highways. At the same time, this study also provides a reference basis for the development of more effective maintenance plans for ordinary national and provincial trunk highways, which is of great significance for the management and optimization of small maintenance costs for highways.
