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.
