    • Abstract:
      This report summarizes the evaluation of the performance of cathodic protection installed on I-89 bridges over

      Gile Pond Road (NH Route 114) during a rehabilitation project in 1987.

      Control bridges of I-89 over Hominy Pot Road, approximately 1.5 miles to the northwest, were also evaluated.

      The Hominy Pot Road bridges received a standard-practice NHDOT rehabilitation of an overlay of 1 ½ inches of

      concrete and a new membrane. The Gile Pond Road bridges each received a four-zone Raychem FEREX 100

      anode cathodic protection system overlaid with concrete and no membrane. This system was tested after

      installation and records indicate it was working properly; however, within 6 years only one of the four zones was

      functioning as expected. Two zones of the four appear to have failed in 1990 and the system failed completely by

      1998.

      Field surveys for this study took place in 2009 using an evaluation protocol as presentation in NCHRP report

      558. The control bridges exhibited more substantial damage in comparison with higher rebar loss, in addition to

      amounts of concrete delamination and spalling.

      The cathodic protection system did provide some benefit to these bridges; however, the system failed and is

      no longer provides protection. The particular system used in this installation proved to be unsuccessful at

      most installations in the U.S.
