What are the key components evaluated during bearing condition assessments?

Angel Patricio Garcia

“Key components evaluated during bearing condition assesments include the bearing material itself (elastomer, steel, etc.), its anchorage to the substructure and superstructure, and its overall alignment and movement capability. For elastomeric bearings, inspectors check for cracking bulging, delamination, hardening, or excessive deformation, while steel bearings are examined for corrosion, wear, and distortion. The anchorage is inspected for corrosion, cracking, or loose bolts and fasteners, and the bearing's alignment and movement are assessed to confirm its properly positioned and able to accommodate expected thermal and rotational movement without undue restraint. Any distress in these components can signal potential problems affecting both the bearing's performance and the bridge's overall structural integrity.”
