Field Evaluation of Bonded Concrete Overlays

Concrete Pavement Overlays and Failure Mechanisms

instrumentation of a bonded concrete overlay (BCO) section located in Houston, Texas, where debonding of the overlay was measured and discussed. Finally, the evaluation of a life cycle cost analysis (LCCA) program is evaluated and its use recommended in future overlay projects. 17. Key Words Delamination, debonding, bonding concrete overlay

Research Program - Evaluation of Thin Polymer Overlays for

Thin composite polymer overlays are a cost-effective method for extending the service life and serviceability of concrete bridge decks by filling concrete cracks and increasing skid resistance. The overlay is a thin (1/4 to 1/2 inch) layer of polymer that seals existing cracks and is embedded with aggregate for wear and skid resistance.
