Available in PDF, EPUB and Kindle. Book excerpt: "Bridge decks are expected to proved relatively maintenance-free service for approximately 40 years. It has been found, however, that some unprotected bridge decks require major repairs within 5 to 10 years, and often must be replaced after 15 years of service. This premature deterioration is frequently the direct result of an accelerated corrosion process on the reinforcing steel caused by the intrusion of deicing chemicals into bridge deck surfaces. A number of bridges on the Federal-aid system do not have a protective system on their decks. If these bridge decks were protected now, significant savings could be realized by avoiding more expensive repairs later. One positive method of stopping the corrosion process in reinforced concrete bridge decks is cathodic protection. Cathodic protection (CP) has been used for many ears to control the corrosion of buried pipelines and structures in saltwater environments. During the past 8 years, the Federal Highway Administration (FHWA), through its Demonstration Projects Division, has promoted the use of this technology as a means of preserving existing unprotected reinforced concrete bridge decks. Assistance has been provided to requesting highway agencies for the construction and evaluation of 22 cathodic installations in conjunction with Demonstration Project No. 34, Cathodic Protection for Reinforced Concrete Bridge Decks. This report provides a summary of the information furnished by participating highway agencies; it includes project selection criteria, design considerations, construction procedures and problems, and performance criteria and results"--P. i.

Download or read book Cathodic Protection of Concrete Bridges written by Jack E. Bennett and published by Strategic Highway Research Program (Shrp). This book was released on 1993 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The deteriorating conditions of reinforced concrete bridges demands new and innovative technology for the repair and rehabilitation of these bridges. The damage caused by the corrosion of steel reinforcement is a prime factor of bridge deterioration. Cathodic protection is emerging as the leading method for the protection of these damaged bridges. The recent innovation of conductive concrete has led researchers to consider using this new concrete matrix for cathodic protection. This study determines the feasibility of conductive concrete for cathodic protection. Four test slabs were cast with conventional reinforced concrete specified by the Michigan Department of Transportation (MDOT) for bridge decks. Steel electrodes were placed on these conventional concrete slabs with a conductive concrete overlay. Conductive concrete is a proprietary concrete matrix which generates an electrical charge through the overlay. Once the concrete slabs were allowed to cure, the slabs were monitored to determine the effectiveness of the conductive concrete overlay for cathodic protection.

Available in PDF, EPUB and Kindle. Book excerpt: Bridge deck and substructure deterioration due to the corrosive effects of deicing chemicals on reinforcing steel is a problem facing many transportation agencies. The main concern is protection of older bridges with uncoated reinforcing steel. Many different methods have been tried over the past years to repair bridge decks. The Iowa system of bridge deck rehabilitation has proven to be very effective. It consists of scarifying the deck surface, removing any deteriorated concrete, and overlaying with low slump dense concrete. Another rehabilitation method that has emerged is cathodic protection. It has been used for many years in the protection of underground pipelines and in 1973 was first installed on a bridge deck. Cathodic protection works by applying an external source of direct current to the embedded reinforcing steel, thereby changing the electrochemical process of corrosion. The corroding steel, which is anodic, is protected by changing it to a cathodic state. The technology involved in cathodic protection as applied to bridge decks has improved over the last 12 years. One company marketing new technology in cathodic protection systems is Raychem Corporation of Menlo Park, California. Their system utilizes a Ferex anode mesh that distributes the impressed direct current over the deck surface. Ferex mesh was selected because it seemed readily adaptable to the Iowa system of bridge deck rehabilitation. The bridge deck would be scarified, deteriorated concrete removed, Ferex anode mesh installed, and overlaid with low slump dense concrete. The Federal Highway Administration (FHWA) promotes cathodic protection under Demonstration Project No. 34, "Cathodic Protection for Reinforced Concrete Bridge Decks."
