Abstract
The expansion joint with an elastomer seal has longitudinal frames made from aluminum extrusions and are mounted by anchor bolts in a pavement or bridge deck concrete. The elastomer seal is fixed in the longitudinal frames by elongated tongue and groove couplings, and the joint space is spanned by at least one shallow, V-shaped elastomer wall which deforms downwardly as the joint width becomes narrower. The longitudinal frames are held in position in steps in the concrete adjacent to the joint by the anchor bolts, at least some of which have threaded ends projecting upwardly through the bottom wall into an upwardly facing longitudinal channel.
