Synthesis of current and projected concrete highway technology.

This synthesis summarizes the results of an extensice search and review of available literature in the field of concrete materials, construction practices, and major application areas as applied to highway construction technology. The synthesis covers current and projected developments in materials systems, including cements, aggregates, admixtures, fibers, and sealers. General topic areas in the fields of concrete production and highway construction covered by this synthesis include mix proportioning, batching and transport placement, finishing, and curing. The synthesis includes information on specific applications areas in the highway industry. These applications focus on repair and reconstruction and include 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, is also discussed in detail. The appendix describes the history of and new developments in concrete pavement construction on the European continent.
