Abstract
The construction, activation, and initial performance of a mesh anode cathodic protection system on a bridge deck are described. The deck was in a badly deteriorated condition prior to repair. A detailed condition survey was made, including the measurement of rates of corrosion using linear polarization equipment. Two similar titanium mesh anodes, one of North American and the other of U.K. origin, were installed for comparative purposes. The anodes were embedded in a conventional concrete overlay.
Nine months after activation, both anode materials were operating satisfactorily, although the current density required to satisfy the 100 mV potential shift criterion was higher than for other Ministry installations.
