VIDEO 'BUILDING THE NOTCHED WEDGE JOINT' SHOWS HOW AND WHY

A construction technique that both improves the performance of a road and relieves paving crews from a difficult task is a pretty rare find. The notched wedge joint is just such a find. Research performed in several states by members of the National Asphalt Pavement Association (NAPA) in cooperation with the National Center for Asphalt Technology shows that the notched wedge joint ensures excellent performance by increasing density along the joint. An added advantage is that when the notched wedge joint is used, there is no lane dropoff. NAPA's new videotape, "Building the Notched Wedge Joint" explains the techniques and advantages of building roads using the notched wedge joint.
