Repairing Bridge Deck Cracks

Many times bridge decks have more cracks than is practical, from a cost and downtime perspective, to be repaired by crack injection. These are often referred to as "alligator" cracks or "spider webs." The deck may be cracked through the entire depth of the concrete slab or cracked only in the unbonded concrete overlay.

5.0 Construction Procedure

The recommended minimum repair length is 1.8m (6 ft) for repairs provided with mechanical load-transfer devices, and 2.4 - 3m (8 -10 ft) for repairs with aggregate interlock joints. All repairs should be full-lane width. The minimum recommended distance from the full-depth repair joints to the nearest transverse crack or joint is 1.8m (6 ft).
