Download Long-term Performance of Polymer Concrete for Bridge Decks Book in PDF, ePub and Kindle
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.

Chloride-ions penetrating into bridge decks and corroding the steel have been a major problem. As the steel corrodes it exerts stresses on the surrounding concrete. When the stresses exceed the strength of the concrete, cracks or delaminations occur. This, of course, causes deterioration and spalling of bridge deck surfaces. Both the Latex and Iowa Method were used to repair bridge decks for this project. The concrete was removed down to the steel and replaced with approximately 1 1/2 inches of low slump or latex modified concrete. The removal of unsound concrete below the top layer of steel was sometimes necessary. The objective of this project was to determine if the bridge overlays would provide a cost effective method of rehabilitation. To do this, unsound and delaminated concrete was removed and replaced by an overlay of low slump or latex modified concrete.

Download Performance of Bridge Deck Concrete Overlays Book in PDF, ePub and Kindle
This paper documents performance of twelve concrete bridge decks in Washington State that were rehabilitated and/or protected with latex-modified concrete and low-slump dense concrete overlays in order to prevent further deicing salt penetration and concrete deterioration caused by reinforcing steel corrosion. An evaluation is made of the factors that have affected the serviceability of those overlaid bridge decks, and recommendations are made based on that evaluation for the design and construction of concrete overlays in order to improve bridge deck performance and to extend bridge deck service life. The factors evaluated are overlay freeze-thaw scaling, surface wear and skid resistance, surface cracking, bond with the underlying deck, chloride and water intrusion, and finally the concrete overlay's ability to retard continued reinforcing steel corrosion and corresponding concrete deterioration.

Download Performance and Constructability of Silica Fume Bridge Deck Overlays Book in PDF, ePub and Kindle
The effects of construction practices and material properties on the performance of concrete bridge decks are evaluated. Emphasis is placed on comparing bridge decks with silica fume and conventional concrete overlays and determining if the silica fume overlays commonly used on bridges in Kansas are performing at a level that justifies the extra cost and construction precautions. Forty continuous steel girder bridges, 20 with silica fume overlays, 16 with conventional overlays and four with monolithic bridge decks are included in the study.
