Book Construction of a Thin bonded Portland Cement Concrete Overlay Using Accelerated Paving Techniques

Download or read book Construction of a Thin bonded Portland Cement Concrete Overlay Using Accelerated Paving Techniques written by Kenneth H. McGhee and published by . This book was released on 1992 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Portland Cement Concrete Overlays

Download or read book Portland Cement Concrete Overlays written by Kurt D. Smith and published by . This book was released on 2002 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Evaluation of a Thin bonded Portland Cement Concrete Pavement Overlay

Download or read book Evaluation of a Thin bonded Portland Cement Concrete Pavement Overlay written by Thomas Elliott Freeman and published by . This book was released on 1996 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report discusses the performance of the Virginia Department of Transportation's first modern rehabilitation project involving a thin-bonded portland cement concrete overlay of an existing jointed concrete pavement. The performance of the rigid overlay, which was constructed in a fast-track mode to minimize lane closure time, was evaluated by detailed condition surveys conducted annually throughout a 6-year analysis period to identify, document, and monitor the occurrence of distress. The roughness of the overlay was also measured annually with an accelerometer-based inertial road profiler to permit an examination of the effects of surface deterioration on ride quality. After 6 full years of service, which included only minimal maintenance, the pavement overlay remained in good overall condition. Although the ride quality of the overlay remained virtually unchanged throughout the period, a significant increase in the occurrence of low-to-moderate-severity joint spalls, corner breaks, and to a lesser extent transverse cracks was noted during the fifth and sixth years. The extrusion of compression seals and the subsequent infiltration of water into the pavement structure probably contributed to the observed localized failure of the overlay/substrate bond in the vicinity of joints. This condition, in turn, weakened the pavement's structural capacity at panel edges and thereby resulted in the formation of corner breaks and cracks parallel with and near transverse joints. The consideration of thin-bonded concrete overlays constructed in a fast-track mode is recommended as a viable rehabilitation alternative for jointed concrete pavements that are not severely distressed. However, careful attention to joint installation and, in particular, joint maintenance is recommended for similar future rehabilitation projects.

Book Performance of Nongrouted Thin Bonded P C C Overlays

Download or read book Performance of Nongrouted Thin Bonded P C C Overlays written by Mark K. Kaler and published by . This book was released on 1986 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Iowa road system has approximately 13,000 miles of Portland Cement Concrete Pavements, many of which are reaching the stage where major rehabilitation is required. Age, greater than anticipated traffic, heavier loads and deterioration related to coarse aggregate in the original pavement are some of the reasons that these pavements have reached this level of distress. One method utilized to rehabilitate distressed or underdesigned PCC pavements is the thin bonded Portland Cement Concrete overlay. Since the introduction of thin bonded overlays on highway pavements in 1973, the concrete paving industry has made progress in reducing the construction costs of this rehabilitation technique. With the advent of the shotblast machine, surface preparation costs have decreased from over $4.00 per square yard to most recently $1.42 per square yard. Other construction costs, including placement, grouting and sawing, have also declined. With each project, knowledge and efficiency have improved.

Book Ultra thin Portland Cement Concrete Overlay Extended Evaluation

Download or read book Ultra thin Portland Cement Concrete Overlay Extended Evaluation written by James K. Cable and published by . This book was released on 2005 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Iowa ultra-thin project demonstrated the application of thin portland cement concrete overlays as a rehabilitation technique. It combined the variables of base preparation, overlay thickness, slab size, and fiber enhancement into a series of test sections over a 7.2-mile length. This report identifies the performance of the overlays in terms of deflection reduction, reduced cracking, and improved bonding between the portland cement concrete (PCC) and asphalt cement concrete (ACC) base layers. The original research project was designed to evaluate the variables over a 5-year period of time. A second project provided the opportunity to test overlay rehabilitation techniques and continue measurement of the original overlay performance for 5 additional years.

Book Portland Cement Concrete Resurfacing

Download or read book Portland Cement Concrete Resurfacing written by Kenneth H. McGhee and published by Transportation Research Board. This book was released on 1994 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
