Abstract
A method and apparatus is disclosed for producing grooves in plastic concrete bridge decks, airport runways and the like having a cutter bar supporting a plurality of parallel cutter blades adapted to be imbedded in the surface of a deck. The cutter bar is adapted to be moved transversely across the deck and is mounted for pivotal movement on an axis normal to its transverse movement. The extent of pivotal movement is such as to raise and maintain the leading ends of the cutter blades slightly above the surface of the deck during the transverse movement.
