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.

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.

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.

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.
