The maintenance of the water-stable layer is to sprinkle water on the road surface, and then lay a maintenance film on the road surface. The frequency of sprinkling water depends on the rate of water evaporation.

[0003] The existing Chinese patent with the publication number CN212771869U discloses a water-stable base maintenance device, which includes a maintenance bracket, a heat and moisture preservation mechanism, and a sprinkling mechanism. The maintenance bracket includes a cross beam and a support rod. A telescopic support is arranged at the bottom of the cross beam, and a plurality of connecting parts are arranged on both sides of the cross beam. One end of the support rod is correspondingly provided with a connecting piece, and the other end of the support rod is provided with a support seat; the heat and moisture preservation mechanism includes a cylindrical shell, a cloth feeding roller and a heat and moisture preservation cloth are arranged in the cylindrical shell, an opening for the heat and moisture preservation cloth to be laid is arranged on the cylindrical shell, and a cloth feeding rod is connected to one end of the heat and moisture preservation cloth located outside the opening.

[0004] In view of the above related technologies, it is found that the spraying width of the existing water-stable base maintenance device is limited, and the spraying width cannot be adjusted according to different road surface conditions. In this way, when the road surface is relatively wide, the maintenance vehicle needs to travel back and forth on the road surface, which not only has low efficiency but also easily damages the road surface.
