Shoulder Wedge MakerThe Shoulder Wedge Maker (SWM) shapes the edge of an HMA mat on shoulderless roads. It mounts on the screed extension face against the end gate of any asphalt paver and develops a 30-degree slope off the edge of the mat to help drivers maintain control of the vehicle and safely return to the driving lane.
