ABSTRACT:
An expansion joint seal assembly for sealing the gap between adjacent sections of a deck structure, such as a highway bridge or parking deck. The assembly includes an elongated body of elastomeric material that has two elongated compression pads extending along each side, and a flexible sealing section joining the two pads together. The compression pads are secured to the roadbed sections on opposite sides of the gap by means of metal cover plates that extend over ribs on the top of each compression pad, and fasteners such as anchor bolts that are secured to the deck sections at points in between the ribs of the compression pads. The anchor bolts extend up through the cover plates, and the heads of the anchor bolts are tightened down against the cover plates to press them against the compression pads and secure the compression pads in firm sealing engagement with the deck sections.
