Abstract
A sealing system and method for sealing an expansion joint in a roadway gap. Channel-shaped members are mounted at each side of the joint. A seal having a bead at each side is sealingly clamped by a retainer bar against the channel member to provide a seal across the roadway gap. The retainer bar is maintained in a clamping position against the seal bead by retainer plates and by a keeper pin which overlies the bar. The bar is forced downwardly into sealing engagement with the bead to permit positioning of the keeper pin over the retainer bar to hold it in clamping and sealing engagement.
