Problems on the maintenance of highway asphalt pavement
Highway asphalt pavement is prone to cracks due to the change of seasonal heating and cooling and the different intensity of use. Attention must also be paid to the maintenance of such road surface, otherwise the cracks may be enlarged. On the maintenance of such pavement Xiao Bian summed up some of the issues that should be noted, mainly the following content.
First, repair the damaged and cracked areas in time. Cracks on highway asphalt pavement should be treated with care and must be dealt with promptly. Because the material of asphalt is ductile, if there is a crack in one place, the next day it may extend or become a bigger crack. Therefore, it was found that cracks or potholes on the highway's asphalt pavement should be dealt with promptly, otherwise it would bring more difficult repair tasks.
Second, check the asphalt pavement regularly. Although the asphalt pavement is relatively strong, it is also prone to damage. Regular inspections should be conducted, and asphalt pavements should be regularly inspected to detect road problems in a timely manner. Because asphalt pavement is often used on highways, the speed of ordinary vehicles is relatively fast. Once problems arise, they have a great impact on driving safety.
Third, road asphalt pavement maintenance should pay attention to the use of different conservation materials in different solar terms. In the winter and summer, the maintenance of asphalt pavement is different. When the road is maintained in winter, the temperature of the asphalt should be high, otherwise it will be hard to be hardened. When the asphalt pavement is maintained in summer, the temperature of the asphalt can be burned. Lower, because bitumen is not prone to solidification in the summer.
Fourth, the maintenance of asphalt pavement requires the use of professional conservation vehicles. Maintenance of asphalt road pavement should use professional maintenance vehicles, and special equipment for burning asphalt in vehicles. The use of such a professional vehicle can better accomplish the work of conserving the road. Otherwise, not only the road maintenance will be poor, but also there will be some dangers for the operators. The use of this professional vehicle can reduce the risk of occurrence and can also repair the road surface evenly.
