MONITORING THE EFFECTIVENESS OF A CATHODIC PROTECTION SYSTEM: CASE OF THE NOIRMOUTIER BRIDGE

A cathodic protection system was designed and installed on the Noirmoutier Bridge in France, a reinforced concrete structure over a small pass on the Atlantic Ocean. The design and the installation of the system have met the requirements of the new French standard for cathodic protection of steel in atmospheric concrete. It means that the main effectiveness criterion is the rebar potential under cathodic protection. The initial protection current 1 was determined by using a Elogl polarization plot: this procedure makes it possible to check that the system had been correctly designed and to detect possible shorts in the electrical circuit. Then, after a six month operation, the rebar potential was maintained at level a little lower than -850 mVcse.
