Book Description
This report represents nearly 6 years of collaboration among Federal Highway Administration (FHWA), State, and American Concrete Pavement Association (ACPA) engineers on the subject of Fastrack Concrete Paving. As an outgrowth of activities begun in 1986 in Storm Lake, Iowa, a Technical Working Group (TWG) assembled under the auspices of the FHWA's Special Project 201. Since the first meeting in Alexandria, Virginia, in 1988, the TWG has cooperated to construct pilot projects, test concrete material with the FHWA's mobile laboratory, sponsor workshops and conferences nationwide, simulate exercises on urban project designs, complete ACPA's Technical Bulletin on Fastrack, and support follow-on research. This report formally completes activities carried out under SP-201. It presents key information on opening-to-traffic criteria and pavement slab temperature management. It includes a summary of key projects built around the country in the last 6 years. It also includes a copy of ACPA's new bulletin and closes with reprints of several technical reports that may be of interest to the reader.

Book Description
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.

Book Description
The report describes the Virginia Department of Transportations' first modern experience with the construction of thin-bonded Portland cement concrete overlays of existing concrete pavements and with the fast track mode of rigid paving. The study was conducted in cooperation with the Federal Highway Administration (FHWA) and used a paving mixture verified in an FHWA mobile laboratory. The study showed that the fast track mode will permit lane closure times as short as 48 hours. Of special interest was the finding that adequate strength of the bond between the old pavement and the overlay is not dependent on the use of a bonding grout.

Book Description
This synthesis report will be of special interest to pavement designers, materials engineers, and others seeking information on portland cement concrete resurfacings (overlays) placed over both portland and asphalt cement concrete pavements. Information is presented on the various practices in use for the design, material selection, and construction techniques associated with each pavement type. Additional information is provided on resurfacing experience and performance, including an Appendix cataloging more than 700 existing resurfacing projects in North America. Transportation agencies in the United States are continuing to develop pavement management systems which take an objective and structured approach to life-cycle cost analysis requirements for pavement rehabilitation project analysis. This report of the Transportation Research Board also discusses the considerations involved in the selection of technically feasible resurfacing alternatives. Based on the longitudinal experience of 375 resurfacing projects that were cataloged in 1982 and the more than 700 projects identified in 1993, much useful information on the performance characteristics of portland cement concrete resurfacing is presented.

Book Description
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.
