Methods
Reasonable determination of asphalt pavement structure, the selection of the technical requirements of asphalt, selection of mineral materials, take the timely treatment of the disease, to avoid further deterioration.so as to achieve the purpose of effectively reducing ，ensure good drainage performance.
Conclusion
Investment in the construction of the road is only accounted for 3/10 of the cost of its life cycle, and the rest is the cost of maintenance expenditures. Therefore, we need to pay more attention to the later management of pavement.
Ensure good drainage performance It is strictly forbidden to overload vehicles
Pay attention to the development of new maintenance technology
