ABSTRACT:
An expansion joint for buried inner placement over an expansion seam under a bridge roadway includes padding sheets fixed to the bridge deck on either side of the expansion seam in the deck. Padding slats are fixed to the bridge deck outboard of the padding sheets. A steel plate is superimposed above the padding sheets and padding slats and is provided on its underside with sliding pads and padding slats corresponding to the padding sheets and padding slats on the bridge deck. Rivets are anchored in the deck and accommodated in expansion slots in the sliding pads and steel plate. The rivets and slots are covered by guard covers. The joint is intended to be paved over.
