Expansion joint construction: Expansion joint and reinforcing steel bars (rebars) for reinforced concrete bridge deck. Resteel is coated with green colored epoxy to resist corrosion from winter road salting. Rebars are placed in top and bottom of slab, both longitudinal (along length of bridge deck) and transverse (across deck). Rebars are tied at intersections to provide support and hold them in place until concrete is cast around them for bridge deck. In photo center is a cast-in-place expansion joint of galvanized (zinc coated) steel. It will be anchored in the cast concrete by the galvanized steel shear studs welded to the joint edges. The expansion joint gap/space is temporarily filled with polystyrene during the concrete construction process. It will be replaced by elastomer filler that can expand and contract as the bridge deck expands and contracts with daily temperature changes. Broadway Bridge, Ann Arbor, 2003.
