Abstract
In view of long term maintenance of its infrastructure facilities the Dutch Highway Administration (Rijkswaterstaat) has repaired over 1.500 heads of prestressed beams and provided them with cathodic protection (CP). The heads of these beams showed moderate to severe damage due to rein forcement corrosion caused by the penetration of chiorides from leakingjoints, which required adequate intervention on the short term. By means of cathodic protection the corrosion process has been halted, so that the risk of further degradation of the beams and possible failure of the pre-stressing steel tendons has been minimized. In addition, the concrete repairs in the chioride contaminated parts of the beams will be durable.
