SPECIALTY CONTRACTING: HIGHWAY GROOVERS AND GRINDERS. SPECIALTY MARKET IN A GROOVE

There is an emerging consensus that bridge and runway grooving enhances safety and that highway grinding can be accomplished at less than half the cost of an asphalt overlay. Specialized subcontractors use state-of-the-art machines with rotating diamond-tipped saw blades to cut drainage and traction grooves in bridge decks and airport runways and to smooth out rough-riding concrete highways. Several states such as New York and Maryland have mandated the grooving of new and reconstructed bridges, and more than half the states have used or plan to use highway grinding to correct rough riding conditions on old pavement or newly poured surfaces. The details of a grooving job are briefly described. It is noted that grooving and grinding have evolved into very cost-effective methods of restoring skid resistance and acceptable profile to a pavement.
