Conductive Overlay in Conjunction with an Active Cathodic Protection System

摘要

The report describes the development of a premixed electrically conductive polymer concrete overlay for use on bridge decks and other concrete members, in conjunction with cathodic protection systems. The development of a conductive overlay culminated in the installation of such an overlay on a full-bridge deck in Pulaski, Virginia; the active cathodic protection system has operated for 3 months and is being monitored on a monthly basis. The monitoring shall continue for about 18 months. The conductive overlay was placed by a local construction firm with the authors' technical assistance. The cathodic protection system was designed by a corrosion engineering firm and installed by the contractor.
