By using statewide specifications, we use our machines to smooth out any bumps and irregularities in the road. We start by using our highspeed profiler to identify the areas, then go through those areas to grind out any problem spots using our grinder. For bridge decks we use a TBG to add grooves to bridge decks for water drainage and traction.
