Five individual cathodic protection systems were installed on the U.S. 87 Missouri-Pacific Railroad overpass structure in Big Spring, Texas. The cathodic protection systems were installed in October 1988 as a demonstration project to compare the various systems. Three distributed anode types were used to protect the bridge deck: (1) titanium mesh; (2) conductive polymer; and (3) carbon strand. A hot-sprayed zinc conductive coating anode was applied to sidewalks and a median on the bridge deck, and a conductive paint anode was applied to a bridge bent. Performance data have been collected for each system since installation. The purpose of this study was to assess the performance of the five different cathodic protection systems installed on the Big Spring bridge.

This document provides explanation, guidance, and direction concerning cathodic protection of concrete bridge elements to the highway engineer who wants to incorporate cathodic protection in a bridge project. The manual which provides background information on corrosion fundamentals, is divided into 3 parts: design, construction, and operation and maintenance. An appendix provides standard specifications for cathodic protection systems for both decks and substructures. The document is intended to be a useful reference for engineers who design and prepare specifications or who oversee turnkey operations.

Performance data have been collected for each system since installation. The titanium mesh anode continues to function while the conductive polymer anode has failed and the carbon strand anode exhibits instability. The hot-sprayed zinc anode system failed early in the study and the conductive paint anode system shows signs of failure.

Revised and updated, this second edition of Cathodic Protection of Steel in Concrete and Masonry covers both reinforced concrete and masonry structures, describes in detail the overall design factors involved in cathodic protection (CP), and also provides a theoretical basis for why it works. It refers to the new European standard EN 12696 for cath

The conference focused on the major problem facing highway and bridge engineers: deterioration of concrete bridge decks caused by corrosion of the reinforcing steel. The conference was aimed primarily at giving bridge owners and engineers an understanding of cathodic protection as the only means to stop corrosion on bridge decks.

Since the 1970s, research projects and field studies have been conducted on different methods for protecting reinforced concrete bridges from corrosion damage. The methods include alternative reinforcement and slab design, barrier methods, electrochemical methods, and corrosion inhibitors. Each method and its underlying principles are described, performance results of laboratory and/or field trials are reviewed, and systems are evaluated based on the results of the trials. Using performance results from the studies and costs obtained from transportation agencies, an economic analysis is used to estimate the cost of each system over a 75-year economic life using discount rates of 2%, 4% and 6%.

Five systems of cathodic protection were installed on the US 87 Missouri-Pacific Railroad overpass in Big Spring, Texas. The design and construction of the systems are summarized in this report. The Federal Highway Administration sponsored the demonstration project, which was intended to be used as a means of comparing the various systems. Later reports will provide updates of how effectively the systems operate in this installation.
