Abstract:Tests were made on portland cement and resinous concrete overlays to determine their suitability as overlays for deteriorated concrete bridge decks. Direct shear strengths of overlays bonded with epoxy, portland cement grout, and latex modified cement grout were compared with those applied with no bonding agent. Freeze-thaw tests were made to determine durability of bonding agents and of overlay concretes. Load tests were made on 8 ft span beams to determine the stiffening effect of overlays and the effect of repeated loadings on overlaid beams. Durability was studied further by gradually lowering laboratory temperature to 20°F during periods of repeated load applications.
