The invention discloses a rapid permeable asphalt spraying device for an expressway, which relates to the technical field of expressways, and solves the problems that according to an existing asphalt spraying device, the spraying position is difficult to adjust, accurate road surface construction is difficult, asphalt is easily sprayed to a road surface well lid and road edge stones and is difficult to clean, and asphalt liquid is easily dispersed in the spraying process, theasphalt material is wasted and the environment is polluted at the same time. The device comprises a mounting seat, a swing driving assembly andfour sets of swing connecting pieces, wherein the swing driving assembly is arranged at the upper part of the mounting seat; and the four sets of swing connecting pieces are connected to the right side of the mounting seat through hinges. The device has good adjusting capacity, the spraying range can be adjusted according to needs, well lids and other parts on the ground can be effectively avoided, uniform spraying can be guaranteed, the precise construction range is guaranteed, pollution of asphalt liquid to irrelevant objects is avoided, the better environment-friendly effect is achieved, and waste of the asphalt liquid is reduced.
