ABSTRACT:
An expansion joint for use between spaced apart ends of adjacent sections of a highway, bridge or the like, the expansion joint having a pair of aligned boxes embedded in the pavement material of the ends of the sections, one or more support rails each of which is slidingly supported at its opposed ends in the aligned boxes, and one or more intermediate rails between the spaced apart ends and extending transversely of the support rails, each of the intermediate rails being affixed to and supported thereby. Each of the boxes has a removable top plate whose top surface is coplanar with the driving surface of the highway, bridge or the like, the top surface having a steel plate with upper and lower layers of an organic material affixed to its upper and lower surfaces, respectively. The metal plate is secured to an upstanding wall of the metal box by threaded fasteners each of which has its top below the top surface of the upper layer of the organic material, the upper layer having holes therein to permit the insertion and removal of the threaded fasteners. A removable plug of an organic material is removably inserted into each of the holes in the upper layer to seal such holes.
