Abstract:The pile cap of an end bent of the Morganza Spillway Bridge suff ered extensive damage at the girder bearing
locations on one side, due to the pounding of the girders at these locations by the adjacent concrete deck
located on the approach side of the bent. The lack of a gap or an expansion joint between the two adjacent
bridge decks contributed to the distress in the pile cap. The pounding caused heavy spalling of the concrete
on the west face of the pile cap at the girder bearing locations and the spalling extended all the way to
bearing plates. In conjunction with a major repair that was being undertaken on the bridge, the repair of the
damaged pile cap (Bent 458) is proposed using the latest technology.
