This report presents the latest information on the design, construction and performance of portland cement concrete (PCC) overlays. It describes the four types of PCC overlays that are commonly used in highway pavement applications: bonded PCC overlays, unbonded PCC overlays, conventional whitetopping and ultra-thin whitetopping. Recommended applications, critical design elements, current overlay design methodologies, recommended construction practices, and performance highlights are described for each overlay type. Information is also provided on the selection of PCC overlays as possible rehabilitation alternatives for existing pavements. Taken together, this document addresses the current "state of the technology" of PCC overlays placed on both existing PCC pavements and on existing hot-mix asphalt pavements.

This synthesis reviews the literature in the field of concrete materials, construction practices, and major application areas as applied to highway construction technology. It covers current and projected developments in materials including cements, aggregates, admixtures, fibers, and sealers. Topic areas covered include mix proportioning, batching and transport, placement, finishing, and curing. The applications included here focus on repair and reconstruction including full depth repairs, slab replacement, partial depth repairs, overlays, and recycling. Quality control of concrete including traditional approaches as well as new test methods and quality assurance schemes are discussed. The appendix describes the history of developments in concrete pavement construction in Europe.
