Maintenance vehicle for asphalt pavement of road

The utility model discloses a maintenance vehicle for asphalt pavement of road, which comprises a chassis vehicle, a power unit, a drying cylinder, and a mixing cylinder, wherein the power unit drives the drying cylinder and the mixing cylinder to rotate. After dried by the drying cylinder, the stone material is sent to the mixing cylinder for mixing with the asphalt sprayed in to form the asphalt concrete and eliminate it. The maintenance vehicle for asphalt pavement of road of this utility adopts the bi-cylinder structure of drying cylinder and mixing cylinder, to change the proto task program: the mode that the feeding to drying to mixing and to layout of the filling is divided into two steps to complete by one cylinder, to the mode that the drying cylinder and the mixing cylinder complete continuously and without stop, so it shortens the pouring time of the finished product ingot, that is to say the asphalt concrete, improving the production efficiency of the asphalt concrete; in addition, compared with the interrupted operation of the single cylinder structure, the continuous operation of the drying cylinder can reduce heat energy loss, lower the consumption of the drying fuel, reduce the manufacturing cost of the asphalt concrete.
