Abstract

Corrosion of steel reinforcing bars in concrete bridge structures due to the intrusion of chloride ions from seawater or de-icing salts affects many structures in the nation's highway system. Over the past decade cathodic protection has evolved as a promising technology for arresting corrosion. The development of materials, equipment, and methods for applying cathodic protection is in a dynamic state. Through cooperative efforts with academia, industry, and the engineering community, the Florida Deparment of Transportation has developed several innovative corrosion protection systems which incorporate technologies from a wide variety of specialty areas including telemetry, photovoltaics, polymers, and specialty components developed as part of the national defense program. This paper provides an overview of corrosion and cathodic protection technology and focuses on the potential for adaptation of existing technologies into preservation of highway bridge structures.
