Removing of selected areas chosen by the contracting authority; cutting the full depth of the pavement; removal either by breaking and digging with excavators/backhoes or by utilizing a lift-out method (lifting an entire slab). Replacing/adding steel as needed/desired by authority, replacing it with new concrete, and finishing flush with existing concrete.

Typically removing 3 to 5 inches off the top of the road by milling or other means at locations chosen by the contracting authority; sandblasting the removed area clean and replacing it with new concrete finished flush with the existing concrete. The new concrete is typically bonded to existing concrete by a grout place immediately before concrete placement.

The addition of steel to a road that was paved without it. Typically done by sawing six 2 ó inch “slots” (like in the picture) on an already existing joint or crack in the roadway; jackhammering the area sawed to remove the old concrete to allow space for a new dowel bar inside the “slot”, elevating it off the bottom with a plastic chair, and then filling the slot with grout to create a load transfer point at the existing joint.

If extensive concrete deterioration moves beyond the level of simple cracks, structural repairs become necessary. After removing unsound concrete and sandblasting the area, new concrete is placed and cured in accordance with all safety protocols.
