A Slotted Cathodic Protection System for Bridge Decks


Book Description

A non-overlay, slotted cathodic protection system was installed two years ago on a concrete bridge deck in Virginia. The design, installation, and operation of this system are fairly straightforward. A protective current density of 1.6 mA/ft2 (17 mA/m2) as determined by E-log I curves has been applied constantly on the deck. Various tests have shown that polarization of the structure has been achieved. After more than 18 months in service, the various components of this system appeared to be in good condition.

Proceedings of the Conference on Cathodic Protection of Reinforced Concrete Bridge Decks, San Antonio, Texas, February 12-13, 1985


Book Description

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.

Interim Report


Book Description

This interim report describes Virginia's experience in installing its first cathodic protection system for a bridge deck. The installation was completed with practically no problems. Very minor problems have been encountered with the rectifier/control unit. However, these problems haven't prevented the system from functioning as designed.




Field Inspection Guide for Bridge Deck Cathodic Protection


Book Description

"This report is intended as a guide for inspectors who are unfamiliar with the construction procedures used when installing cathodic protection systems on reinforced concrete bridge decks. The text has been divided into sections in an effort to simplify the report and make it easier to locate desired information. The first four sections provide some basic background information about cathodic protection. Section V discusses a general system installation; each of the major components are discussed to provide a basic understanding and act as a checklist during the installation process. Section VI discusses the various types of systems that have been installed, to date. This is not intended to be an all-inclusive manual. Rather, it is to be used as a guide to help overcome some of the most common problems associated with the installation of cathodic protection systems. It is meant to support and supplement good specifications, not replace them"--Page 1







Cathodic Protection of Concrete Bridges


Book Description

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.
