ABSTRACT:
A camming surface, having a plurality of camming groups, is moved along, or relative to, the surface of the roadway to regulate installation of depressions. Each camming group is capable of regulating elevation of a rotary cutting tool where the rotary cutting tool may move down and into contact with the surface of the roadway and move up and out of contact with the surface of the roadway. Use of a plurality of sections may be used to cooperate to form the camming surface. Inserts are disclosed for positioning relative to the camming surface to selectively eliminate installation of a depression at a position on the roadway associated with a respective camming group. Use of such inserts allow for installation of skip pattern installations. The ability to move the inserts to any of the camming groups allow for uniform wear of the camming surface following sustained use of the installation machine.
