Abstract (en)
An asphalt finisher includes a tractor, a hopper installed on a front side of the tractor, a conveyor that conveys a paving material inside the hopper to a rear side of the tractor, a screw that lays and spreads the paving material conveyed by the conveyor and scattered on a road surface in a vehicle width direction, and a screed device that lays and levels the paving material laid and spread by the screw on a rear side of the screw. An operation of a transport vehicle is synchronized to correspond to an operation of the asphalt finisher.
