How should an inspector evaluate a bridge with visible delamination in concrete?

• A. Ignore Delamination If There Is No Visible Exposed Rebar.
• B. Replace The Entire Deck Immediately.
• C. Assess Extent, Potential Load-Bearing Impact, And Consider Temporary Posting Or Repairs; Escalate If Necessary.
• D. Seal The Delaminated Area With Epoxy.

Answer: (C)

Visible delamination in concrete signals a separation between layers that can hide deeper damage and possible corrosion of reinforcing steel. The key action is to assess how extensive the delamination is and whether it could affect the deck’s load-carrying capacity. Start by documenting the area, measuring its size, and checking if reinforcing steel is exposed or deteriorated, since these factors influence safety and repair needs. Evaluate the potential impact on serviceability and strength, and determine if temporary measures are warranted—such as load posting or restricting traffic—while a repair plan is developed. If the condition could alter performance or is beyond routine repair capability, escalate to a structural engineer or the responsible authority for formal evaluation and recommendations. Epoxy sealing might be used as a surface treatment in some cases, but it does not restore structural strength and should not be the sole remedy. Treat the delamination as a condition requiring careful assessment and a coordinated repair plan rather than a quick fix or ignored defect.
