Section 4: Bridge Beams

Risks of Chemical Damage

Beams exhibit increased risks to corrosion due to cover reductions, high stress steel design, and concentrated chemical solution saturating end zones when joint seals are broken.

Repair of Joint Systems

Maintenance personnel should repair and maintain joint systems ensuring the protection created by the sealed joint systems.
