Abstract:
Bonded concrete overlays are frequently used to repair concrete pavements, bridge decks, and industrial floors. They provide significantly higher load-carrying capacity and stiffness than unbonded overlays of equal thickness. Over 30 years of Swedish research indicates that a durable bond between the overlay and the existing concrete can be achieved with proper removal, surface preparation, placement, and curing.
