Abstract (en)
An asphalt finisher (100) includes an information acquiring device (51) for acquiring information about a surface of a pavement compacted by a screed (3) and a controller (50). The screed (3) includes a front side screed (30) and a rear side screed (31) whose positions are shifted along the length of the asphalt finisher. The controller (50) determines whether a level difference (LD) is formed between a surface of pavement material compacted by the front side screed (30) and a surface of the pavement material compacted by the rear side screed (31) based on the information acquired by the information acquiring device (51).
