1, daily highway maintenance. After the road is completed and put into use, there will be wear and tear, so it is necessary to carry out daily maintenance on the road.

2. Repair of damaged pavement. For example, if there is a crack on the pavement, then use a professional road maintenance vehicle, equipped with professional repair equipment, so that the pavement can be repaired in time.

3. Pavement maintenance in case of weather disaster. For example, when a snowstorm breaks out, a lot of snow accumulates on the road, which is not conducive to the safety of vehicles. This is also an important part of highway maintenance, because ensuring driving safety is the first responsibility.

4, roadside greening and health work. In the daily road maintenance work, another important task is to ensure the sanitation of the road surface, clean the road surface garbage and ensure the cleanliness of the road surface.

Extended data:

Strengthening the preventive maintenance of highway is the premise of prolonging the service life of highway and maintaining the good use function of pavement.

In the daily maintenance work, when the pavement is not damaged or just shows signs of disease, preventive maintenance measures are taken according to the principle of "accurate prediction and repair before damage" to eliminate the disease in the bud.

In view of pavement cracks, technical measures are taken to prevent rainwater from invading the pavement and damaging the subgrade structure according to the principle of "irrigation must be carried out in case of cracks, and irrigation must meet the standards".
