Abstract
A work machine for removing asphalt from a roadway is disclosed. The work machine includes a removal device configured to remove asphalt from a roadway surface, and a grinding device configured to fracture the removed asphalt. The work machine also includes a funnel-shaped ramp configured to guide the removed asphalt from the removal device to the grinding device. A width of the removal device is larger than a width of the grinding device, and the funnel-shaped ramp is configured to fold the outer edges of the removed asphalt over itself before the removed asphalt reaches the grinding device.
