Book Description
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.

Book Description
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 Description
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 Description
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.
