This 12-page document describes the use of epoxy-coated reinforcing steel in bridges and includes four case histories from around the United States. It also provides guidance on the job site handling of epoxy-coated reinforcing steel, as well as a brief detailed selection on corrosion mechanisms. (2012)

EIG has recently produced a report evaluating the laboratory and field research comparing the performance of epoxy-coated and galvanized reinforcing steel. This 6-page report shows why epoxy-coated bars have become the most commonly specified reinforcing steel bars to protect against chloride-induced corrosion. Epoxy-coated reinforcing steel has been used in over 67 times more bridges covering over 90 times more area than galvanized reinforcing steel. The report also shows that galvanized decks constructed between 1974 and 1984 are 2-1/2 times more likely to show poor performance compared with decks containing epoxy-coated bars.

EIG is pleased to announce the publication of a Case History featuring the Jeremiah Morrow Bridge on I-71. This twin span 2200 ft segmental concrete box girder bridge will be completed in 2015 and use approximately 5000 ton of epoxy-coated reinforcing steel.

In 2010, a report was prepared for the Michigan Department of Transportation on the expected service life of concrete bridge decks. This report concluded that decks with epoxy-coated reinforcing steel would provide a service life of 70 years and that the use of Markov transition probabilities is acceptable and accurate in analyzing bridge data. This document summarizes that report.

Owners of concrete structures are looking at ways of cost-effectively protecting new assets such as bridges and parking garages against corrosion. In order to conduct economic analyses for corrosion-induced damage, knowledge of chloride ingress, the amount of chloride to initiate corrosion, corrosion rates and the amount of corrosion to cause cracking are required. This 4-page document summarizes key findings from a study conducted at the University of Phoenix relating to the cost and performance of concrete bridge decks containing various corrosion-protective systems. The study found that the life-cycle cost of a deck using epoxy-coated reinforcing steel was almost half that of the deck containing uncoated reinforcing steel and approximately 35 percent lower than a deck containing Type 2205 Stainless steel. This report is of value to those evaluating alternative corrosion-protection systems for concrete bridges.

In 2011, the University of Kansas Center for Research published a report titled “Evaluation of Multiple Corrosion Protection Systems for Reinforced Concrete Bridge Decks,” based upon a Ph.D. thesis. Major funding for this work was provided by the Kansas Department of Transportation and the Federal Highway Administration. The 487-page report provides an in-depth evaluation of the performance of corrosion inhibitors, epoxy-coated reinforcing steel and stainless steel and includes documentation of extensive laboratory and field research, an evaluation of the amount of corrosion to cause cracking, and an economic analysis. The research supports continued use of epoxy-coated reinforcing steel as corrosion rates were substantially reduced even in cracked concrete and initial and life-cycle costs were lower than the other systems that were evaluated. This report is of value to engineers and researchers that are considering various corrosion-resistant reinforcing systems.

This 6-page document provides guidance on the use of epoxy-coated reinforcing steel to protect concrete parking garages caused by the penetration of deicing and marine salts into the concrete causing corrosion, cracking and delamination.  It has been stated that parking garages without epoxy-coated reinforcing steel may show deterioration within 10 to 15 years and over $600 million is spent yearly to repair parking decks.  Costs for parking garage repair may also exceed $10 per sq ft.  This document would be valuable to those involved in the design or construction of new parking garages.

This 8-page brochure provides guidance to procedures for inspection of epoxy-coated reinforcing steel during construction and prior to concrete placement. It describes steel identification, transport and handling, bar placement, bar damage and repair and inspection prior to concrete placement. This document would be valuable to anyone that is involved in the placing and inspection of concrete containing epoxy-coated bars.

This 4-page document presents results from tests that compared the performance of ASTM A775 epoxy-coated reinforcing steel and ASTM A1035 low-carbon, chromium reinforcing steel with requirements for ASTM A955 stainless-steel reinforcing steel. The testing found that the ASTM A775 epoxy-coated reinforcing steel had low corrosion rates and met the requirements of this specification, while the ASTM A1035 bars had very high corrosion rates.

This 12-page document provides information on the use of epoxy-coated bars in buildings including sections on Sustainability and LEED Credits, Certification and Quality and specification. Examples of use are presented including the Aqua Building in Chicago, IL; 45 Province Street in Boston, MA; Richmond Olympic Speed Skating Oval in Richmond, BC; and the Kaufman Center for Performing Arts in Kansas City, MO.

During the past 30 years, many papers have been published regarding the performance of epoxy-coated reinforcing bars in Florida. Several researchers have used these structures as a reason to not specify epoxy-coated reinforcing in marine environments. In 2010, two papers were published by the University of South Florida and the Florida Department of Transportation which demonstrate that in appropriate concrete, epoxy-coated reinforcing bars can be used for a 100-year design life. This document summarizes that work.

This 6-page document sumarizes the 110 page report that describes evaluation of 6 bridges in West Virginia containing epoxy-coated bars. This study found that the structures with black reinforcing bars were repaired in 1993, while the structures with epoxy-coated bars are still in good to excellent conditions.

This document presents a summary of work conducted in 2006 on four concrete bridges constructed using epoxy-coated bars, constructed in the mid-1980s. It was further found that coating adhesion was a poor indicator of bar performance and despite poor coating adhesion, a number of epoxy-coated bar segments were found to resist high chloride concentrations (up to five times the threshold normally assumed for uncoated bars).
