Section 4: Bridge BeamsAnchor: #i1000410
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.Anchor: #i1000421
Repair of Joint Systems
Maintenance personnel should repair and maintain joint systems ensuring the protection created by the sealed joint systems.
Figure 5-5. Chemical solution corrosion induced beam damage created by failed joint and poor concrete cover over beam ends.
