Bonded Concrete Overlays: Construction and Performance

Several bonded concrete overlays have recently been placed on street, highway, and airfield pavements using new equipment and techniques. This report summarizes the current state of the art and industry experience as well as reviewing procedures and performance of older bonded overlays. A review and summary of (a) surface preparation of the existing slab, (b) joint and crack treatment, (c) bonding methods, (d) concrete overlay mixtures, (e) curing methods, (f) jointing techniques, (g) performance of recent overlays to date, and (h) the use of reinforcement in bonded overlays are included. Also, a list of important conclusions and research needs is provided. (Author)
