This book was released on 2011 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 423: Long-Term Performance of Polymer Concrete for Bridge Decks addresses a number of topics related to thin polymer overlays (TPOs). Those topics include previous research, specifications, and procedures on TPOs; performance of TPOs based on field applications; the primary factors that influence TPO performance; current construction guidelines for TPOs related to surface preparation, mixing and placement, consolidation, finishing, and curing; repair procedures; factors that influence the performance of overlays, including life-cycle cost, benefits and costs, bridge deck condition, service life extension, and performance; and successes and failures of TPOs, including reasons for both.

Available in PDF, EPUB and Kindle. Book excerpt: This report covers the construction of a 3/8-inch Flexolith overlay on a concrete-filled steel grid bridge deck on SR 0060 in Allegheny County. The application procedure is straightforward with no special equipment needed. However, the contractor's inexperience with the material created application problems on the eastbound deck. Patches were made between coats to level low areas created by non-uniformity of the first two applications. These application problems were eliminated by the westbound deck and no intermediate patches were required.

Book excerpt: The purpose of this study is to evaluate the application of FLEXOGRID, a modified epoxy resin, to a concrete bridge deck. The FLEXOGRID is designed to impart a thin, fast curing, water impermeable protective overlay to the deck. The FLEXOGRID is 1/4 inch thick consisting of 2 applications of an epoxy broadcasted with a hard aggregate. The FLEXOGRID was easy to apply after the bridge deck delaminations were repaired and the entire deck was shotblasted. Only minor application problems occurred which can be corrected for future applications.

Book excerpt: The objectives of the scanning tour included observation of a PPC overlay placement, inspection of existing overlays, and discussion of selected topics related to PPC. The scanning tour comprised a 3-day visit to California. Items related to material properties, mixture and overlay design, laboratory testing, and construction and field testing were investigated. Several recommendations relevant to Utah bridge deck preservation practice were developed based on the findings and then incorporated into a revised UDOT PPC specification.

Book excerpt: This report summarizes the Washington State Department of Transportation's (WSDOT's) 10 years of experience with "epoxy" and "methyl methacrylate" (MMA) thin polymer bridge deck overlays. WSDOT uses a modified concrete as its primary type of bridge deck overlay, but in some cases a bridge's physical characteristics, such as lightweight design or narrow roadway width, will not allow using a modified concrete overlay. Thin polymer overlays provide an alternative. Thin polymer overlays offer more rapid construction, curing in 4 to 8 hours compared to 42 hours for a modified concrete overlay. Thin polymer overlays are lightweight (due to their 3/8 in. thickness, approximately 5 lb/SF versus 19 lb/SF for a modified concrete overlay and are generally less labor intensive and require less specialized equipment than a modified concrete overlay.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes work done on various combinations of monomers and polymer concrete mixes and identifies the mixes showing the greatest potential for use in bridge deck overlays. Presented are test results showing physical properties of various polymer concrete mixes, such as compressive strength, split tensile strength, modulus of elasticity, thermal coefficient of expansion, and shrinkage coefficient. The effects of polymer content, work time, and temperature on various properties are also discussed. The development of two polymer concrete systems with excellent membrane potential are described along with the details of bonding characteristics of several systems. Finally, a polymer concrete mix with suitable properties for deck and pavement patching is detailed.

Available in PDF, EPUB and Kindle. Book excerpt: Premature failure of portland cement concrete bridge decks is of national concern, particularly in those areas where chloride residues accumulate in the concrete from winter deicing operations. West Virginia's research and field usage indicates that the application of a relatively thin (1 to 2-in.) overlay of portland cement concrete or mortar containing a latex modifier may result in a significant increase in the useful life of bridge decks. Eighteen structures, including both new construction and renovation of existing decks, have received the latex-modified concrete overlay. Results to date have been most encouraging.
