A construction method for a high-speed asphalt pavement construction device according to any one of claims 1 to 5, characterized in that: Steps include (1) Make the motion mechanism move, thereby driving the entire device to move; (2) The asphalt material is introduced into the discharge trough, and the scraper (11) scrapes the material to prevent the material from being piled up. The material falls onto the road surface through the discharge port (18). During the falling process, the breaking rod (17) sweeps the asphalt material to facilitate the falling and prevent the discharge channel (13) from being blocked; (3) When the hopper (10) moves, it drives the scraping assembly (19) to move and scrape the falling materials, and the compacting drum (20) rotates to compact the materials for the first time; (4) The visual sensor (21) scans and detects the first compacted road surface, and sends the scanned signal to the controller (4). The controller (4) processes the signal and transmits it to the repair mechanism, and the repair mechanism moves to repair the position that needs to be repaired; (5) The moving drum (23) compacts the repaired road surface again; (6) Then the road edge trimming mechanism moves to cut off and crush the excess paved materials at the edge of the road; (7) The absorption mechanism absorbs the excess material after cutting and crushing.
