1. Stone chip seal
The stone chip seal is the earliest preventive maintenance technology. Its construction method is to spray a layer of asphalt material (hot asphalt, light asphalt, emulsified asphalt, etc.) on the road surface, followed by sand, stone chips or appropriately graded. Aggregate, followed by rolling. The stone chip seal is a simple, easy and inexpensive maintenance method for laying. Its disadvantage is that it requires a long initial maintenance time, the noise is too loud when the car is running at high speed, and the loose aggregate on the road will be taken out by the high-speed wheels and hit and stick to the body and windshield. The loss of material will also lead to the attenuation of skid resistance, so it is generally rarely used on roads with large traffic flow and high-speed driving.
