ABSTRACT:
A heavy vehicle has fixed cross braces mounted on its frame perpendicular to the direction of the vehicle, and close to the surface of a road. Movable cross braces fit within these fixed cross braces, and support a circular cutting tool that can be extended, laterally, to line up with a guide line on the surface of the road, and that pivots up and down to cut into the surface of the road. An additional pivot permits the circular cutting tool to be set level with the surface of the road before a cut is made. A water supply, with suitable nozzles directed at the cutting blades of the circular cutting tool, cools and lubricates the blades while they are cutting into the surface of the road. A source of compressed air with suitable nozzles, that can be directed at the newly cut holes in the surface of the road, cleans out the holes for the installation of safety reflectors.
