Abstract:
Reports 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 8 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. The cathodic protection system was designed by a corrosion engineering firm. The installation of the conductive overlay and cathodic protection system cost less than $18.00 a square foot.
