ABSTRACT:
A machine that cuts sonic noise alert pattern (SNAP) depressions into the upper surface of asphalt highways. This machine is designed to cut depressions having a rectangular shape, with opposing transitional edges, which are relatively perpendicular to the edge of the road surface, and each have a smooth, even transition from the road surface to the cut depression. Further having a predetermined, but variable, depth along the center of the depression cut, with this center of the cut located at a relatively midpoint between the transitional edges. Additionally having an uniform section of virgin, uncut, asphalt located between each set of adjacent depression cuts. The machine, which has at least one rotating cutting head, moves longitudinally, relative to the desired placement of the individual cuts, in a non-stop, uninterrupted manner. The use of an eccentric wheel or eccentric cam provides for the pivotal raising and lowering of the cutting head and further provides for the spacing of the individual cuts as well as their width and depth. The provision is made for use of a round wheel, with the pivotal axle offset from its center, or for the use of wheels of oval or elongated designs. Provision is made for having a machine, such as a skid steer loader, pull or push the cutting head assembly or to have a custom built unit, having no other function than the cutting of SNAP depressions.
