Abstract:We report 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 systems has operated for eight 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 contractor with technical assistance from Brookhaven National Laboratory (BNL) personnel. The cathodic protection system was designed by a corrosion engineering firm and installed by BNL personnel. The installation of the conductive overlay and cathodic protection system cost less than 18 us dollars a square foot.
