Preventive maintenance can prevent pavement diseases and has become a very important aspect of road maintenance. It slows down the deterioration of pavement performance, extends the service life of the pavement, improves the service efficiency of the pavement, and saves maintenance and repair funds. It is usually used for situations that have not yet occurred. Pavement that is damaged or has only minor disease.

Preventive maintenance of pavement is an active maintenance method that has been widely promoted in my country in recent years. Its concept is to take appropriate measures at the right time on the right road section when the road surface has not undergone structural damage and the service performance has declined to a certain extent. Maintenance measures are taken to maintain the performance of the pavement at a good level, extend the service life of the pavement, and save pavement maintenance funds. At present, preventive maintenance technologies commonly used at home and abroad include fog seal, slurry seal, micro-surfacing, simultaneous gravel seal, fiber seal, thin layer overlay, asphalt regeneration treatment and other maintenance measures.
