　　At present, there are two main factors that affect the decision-making of road surface maintenance in China: maintenance philosophy and maintenance funding. For highways, some highway management departments in various regions have established pavement maintenance management systems, and the maintenance funds for some highways in coastal areas are also relatively sufficient. Objectively speaking, there are conditions to make scientific maintenance decisions. However, the actual situation is not very optimistic. We are still accustomed to passive maintenance methods in highway road surface maintenance work, mainly manifested as not treating small diseases, not willing to spend small money, and only running around to put out fires when the road surface diseases worsen. To reverse the current passive situation of highway maintenance work, it requires us to completely abandon outdated maintenance concepts, promote the implementation of preventive maintenance of road surfaces, and extend the service life of road surfaces, improve road service functions, and save maintenance costs by spending more money and doing maintenance early. For ordinary highways, due to the historical arrears of maintenance work, the problem of maintenance funds being squeezed has not been fundamentally solved, and the problem of insufficient maintenance funds is very prominent. Maintenance decisions often aim for "no disconnection" and implement the principle of "priority for bad roads". In fact, this practice of prioritizing the maintenance of bad roads is very unscientific. Due to the implementation of priority maintenance for bad roads, the cost of maintenance per unit mileage is high, leaving us with even less funds to maintain roads with better conditions. Good roads gradually turn into bad roads, forming a vicious cycle. Therefore, for maintenance decisions, the concept of preventive maintenance should be vigorously promoted, and good road surfaces should be continuously maintained to keep them in good condition, rather than constantly repairing poor road surfaces.
