Asphalt road maintenance vehicle old driver tells you that asphalt pavement maintenance is beneficial

Asphalt pavement maintenance vehicles will be divided into three types during the maintenance of asphalt pavement, preventive maintenance, corrective maintenance and emergency maintenance. Prophylactic oxidation means that asphalt pavements have begun to use asphalt pavement conservation vehicles for preventive maintenance before they have been damaged. Corrective maintenance refers to the repair of some localized damage to asphalt pavements or some specific damage. Stressful care, as the name suggests, was to remedy the situation in an emergency. For example, if there are serious pits, cracks, etc. in the asphalt, repairs can only be carried out. Preventative asphalt pavement maintenance is the most effective method that can effectively prolong the service life of pavements. It can also be regarded as an active pavement maintenance method.

1. From the beginning of the service life cycle of asphalt pavement, it is more cost-effective to take preventive measures than to wait for the asphalt pavement to open to use on a certain day. After relevant tests have proved that the effective preventive maintenance of asphalt pavement is to save the cost of an asphalt pavement maintenance cost between six and ten times when no maintenance measures are used.

2. Although the effect of preventive maintenance does not increase the load capacity of asphalt pavement and the structure of road surface, it will effectively increase the service level and service life of asphalt pavement.

3. In a more suitable period of time, the sealing of the asphalt pavement can not only play a role in preventing the water from penetrating into the structural layer of the asphalt pavement, but also effectively control the cracks, looseness and oxidation of the road surface.

In order to choose the most appropriate and correct time period for preventive pavement maintenance, the condition of the road surface can be periodically adjusted to perform non-destructive inspection and test, so that the time for practical prevention and maintenance can be determined.
