• 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.
