Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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 or read book Twenty-Year Performance of Latex-Modified Concrete Overlays written by MM. Sprinkel and published by . This book was released on 1993 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen bridge decks with latex-modified concrete (LMC) overlays ranging in age from two to twenty years and two overlays without latex were studied. The high quality portland cement concrete overlays without latex showed greater negative increases in half-cell potentials, greater increases in chloride content, and a higher percentage of higher rates of corrosion than the LMC overlays. Also, for these two bridges, higher shear and tensile rupture strengths were obtained at the bond interface with LMC than with concrete without latex. Higher rupture strengths were not obtained on the other bridges because of the low strength of the scarified surface of the base concrete. The permeability, half-cell, chloride, rate-of-corrosion, and bond, strength data indicate that the overlays are performing satisfactorily. Also, LMC overlays placed on decks with less than 2 lb/yd3 (1.2 kg/m3) of chloride ion at the rebar can be expected to have a service life in excess of twenty years.

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 paper is based on a research study aimed at determining the relative effectiveness of three bridge deck protective systems (i.e., latex-modified concrete (LMC) overlay, low-slump dense concrete (LSDC) overlay, and cathodic protection (CP) in preventing or halting reinforcing steel corrosion and corrosion-induced deterioration in salt-contaminated concrete. The paper documents the results of testing five LMC, five LSDC, and two CP bridge decks. The test bridges had experienced severe corrosion-induced deterioration and/or severe salt contamination before protection. At the time of testing the average age of both the LMC and LSDC overlays was about seven years, and the average age of the CP installations (slotted system) was five years. Also, among the concrete overlaid decks, seven had been subjects of previous similar investigations. Thus, the study determined changes in the effectiveness of concrete overlay protective systems with time.
