Cathodic protection for reinforced concrete bridge decks (83-08-1)
Abstract
The Oklahoma Department of Transportation contracted
the installation of two cathodic protection systems as part
of the Federal Highway Administration's Demonstration
Project No. 34, "Cathodic Protection for Reinforced Concrete
Bridge Decks". Two different types of cathodic protection
systems were installed under this contract. The first system
known as a "slotted" or non-overlay system consists of anodes
which are installed in slots that have been sawed in the
bridge deck. The second system is an overlay system in which
the anodes are installed on top of the deck and then a 2 inch
high density concrete overlay is piaced. Both systems were of
the impressed current type using the local utility company
for power.
This is the second year evaluation of the project.
