Abstract (en)
An asphalt finisher includes a tractor, a hopper that is provided on a front side of the tractor, a conveyor that transports a paving material in the hopper to a rear side of the tractor, a screw that spreads the paving material, which is transported by the conveyor and is sprinkled on a road surface, in a vehicle width direction, a screed device that levels the paving material spread by the screw on a rear side of the screw, and a measuring device that measures compaction information indicating a degree of compaction, which is a ratio of the paving material leveled on the road surface to voids.
