Abstract (en)
To enhance the quality of pavement of a curved road (RD) . An asphalt finisher (100, 100a, 100b, 100c, 100d, 100e) includes a tractor, a hopper that is provided on a front side of the tractor and that receives a paving material, a conveyor that feeds the paving material received by the hopper to a rear side of the tractor, a screw that spreads the paving material fed by the conveyor on the rear side of the tractor, a screed that levels the paving material spread by the screw on a rear side of the screw, and a controller. The controller is configured to drive the tractor such that a target trajectory (TPS, TPT) is generated based on a line which bisects an area of a road surface leveled by the screed right and left and a predetermined point (Q, P) of the asphalt finisher (100, 100a, 100b, 100c, 100d, 100e) follows the target trajectory (TPS, TPT) . The road surface includes a road surface of a curve portion (LC) of a road (RD) which is a construction target.
