Need. In winter, when the construction temperature of water-stable paving is low, it can be covered with a layer of plastic film and two layers of geotextile for insulation, and there is no need to spray water for maintenance. After the maintenance period of water-stabilized paving, asphalt seal coat or prime coat should be constructed immediately, and asphalt concrete surface layer should be paved in time, so that the water-stabilized base can be exposed to wind, rain and scorching sun for a short time, which can effectively reduce the cracks caused by repeated drying shrinkage.
