The development of specifications for pavement grooving projects is presented. The normal groove is 1/8" to 1/4" in depth, cut by a blade 0.095" wide, spaced on 3/4" centers, and cut in the longitudinal direction. Minimum acceptable coverage of the specified pattern is 95%. Water and residue from the cutting operation are picked up by vacuum pumps. A maximum operational noise level of 86dbA is allowed. Before and after accident studies of pavement grooving projects are presented. Pavement grooving has resulted in a 85% reduction of wet pavement accidents in the grooved areas.
