Bridge Deck and Highway Grooving: Choosing High-Performance Grooving Blades
Direct Answer: Bridge deck and highway safety grooving requires heavy-duty multi-blade arbor gangs fitted with soft-bond, laser-welded diamond grooving blades. Because bridge decks are constructed from high-strength cured concrete with hard granite or river rock aggregates, soft cobalt-bronze bonds are required to allow continuous diamond exposure, preventing blade glazing and ensuring precise 1/8" to 1/4" channel depths across millions of square feet.

Why is safety grooving required on bridge decks?
Grooving cuts narrow channels in concrete pavement to channel water away from tire contact zones, preventing vehicle hydroplaning.
