Abstract (en)
[origin: EP3868956A1] An asphalt finisher (100) includes a tractor (1), a hopper (2), a conveyor (CV) configured to convey a pavement material in the hopper (2) to a rear side of the tractor (1), a screw (SC) configured to lay and spread, at a rear side of the tractor (1), the pavement material conveyed by the conveyor (CV), and a screed (3) configured to lay and level, at a rear side of the screw (SC), the pavement material laid and spread by the screw (SC). The screed (3) includes a main screed (30), a left extendable screed (31L), and a right extendable screed (31R) that are offset relative to each other so as not to overlap with each other in a vehicle-length direction. The right extendable screed (31R) is supported by an upper right guide shaft (63TR) and a lower right guide shaft (63BR). Each of the upper right guide shaft (63TR) and the lower right guide shaft (63BR) is prevented from rotating by detents at both ends thereof, and one of the detents at one end is provided within a width of the main screed (30).
