Abstract:

In 1976 the Federal Highway Administration (FHWA) approved federal aid funding for experimental installations of corrosion protection for reinforcing steel in existing concrete bridge decks. Sixteen of the sixty-nine Kansas bridges with Cost Effective Overlays built between 1976 and 1987 were selected for ongoing monitoring of delaminations, cracking and corrosion potential in the reinforcing bars. Fourteen bridges with low water-cement ratio concrete overlays and two bridges with asphalt membrane protective systems were monitored annually for the life of the overlays. Eight of the low water-cement ratio overlays were constructed with high-cement-content Iowa System Overlays and six with lower-cement-content Kansas System Overlays. The two asphalt membrane overlays were constructed with a non-woven polypropylene fabric membrane laid onto asphalt cement and overlaid with hot-mix asphalt as a wearing surface. A comparison of service life with initial cost of each type of overlay shows that correctly-installed asphalt membrane overlays may have been the most cost effective, followed by the Kansas System concrete overlays.
