Cathodic protection of reinforced-concrete structures exposed to the atmosphere was apphed for the first time to bridge decks contaminated by de-icing salts by R. F. StratfuU in California in 1973 [1,2]. In the years following, design and protection criteria were elaborated, as well as power supply and monitoring systems completely different from those used for cathodic protection of buried steel structures or structures operating in seawater. Above all, it was proved that cathodic protection was a rehable repair technique even in the presence of high chloride contents, where traditional systems of rehabilitation are inefficient or very costly.

The potential of the corroding surface can be monitored periodically by means of a reference electrode. One such example is the corrosion potential measurement of reinforced steel rebar in concrete structures. Corrosion of the steel in reinforced concrete is a major factor in the deterioration of highway and bridge infrastructure. A survey of the condition ofa reinforced concrete structure is the first step toward its rehabilitation. A rapid, cost-effective, and nondestructive condition survey offers key information to evaluate the corrosion, aids in quality assurance of concrete repair and rehabilitation.

Composite materials have also been used to maintain and extend the safe life of bridges and reinforced concrete structures. Indeed, Australian, Japanese and US companies are already focusing on this technique. There are three principal ways in which composites can be used to rehabilitate ageing infrastructure ... 

The structures programme was entirely concerned with corrosion of reinforced concrete bridges suffering from salt induced corrosion. Its work on structures covered physical assessment, cathodic protection, electrochemical chloride removal, physical and chemical methods of rehabilitating bridge components and a methodology of bridge...

Steel) response levels. Accuracy of the presented modeling approaches were demonstrated via comparismi of the model predictions with test results conducted on reinforced concrete wall, column, and panel specimens. The modeling approaches presented are believed to be a significant improvement towards reaUstic representation of the nonlinear response of reinforced concrete walls and columns. ImplementatiOTi of the model formulations into a computational structural analysis platform will allow improved seismic response predictions for existing buildings, for obtaining more reliable performance assessment results and arriving at more informed decisions oti rehabilitation.

Abstract This chapter continues the discussions of the development of advanced polymer composite material applications associated with bridge engineering. It focuses on the rehabilitation of metallic bridge structures, all-FRP composite bridges and bridges built with hybrid systems. Chapter 16 covered the materials used in FRP composites, in-service properties and applications of FRP composites in bridge enclosures, the rehabilitation of reinforced and prestressed concrete bridge beams and columns.

There are 543,019 concrete and steel bridges of which 78,448 are structurally deficient, leaving 464,571 bridges to be maintained for estimating purposes it is assumed that all these bridges have a conventionally reinforced concrete deck. The annualized life-cycle direct cost of original construction, routine maintenance, patching and rehabilitation for a black steel rebar deck costs between 18,000 and 22,000. These costs are both corrosion- and non-corrosion related.
