SUMMARY OF RESURFACING DETERIORATED BRIDGE DECKS IN BRITISH COLUMBIA WITH THIN CONCRETE OVERLAYS IN THE PAST NINE YEARS

The Ontario Department of Highways found that asphalt used as a protective cover on concrete bridge decks was not as imprevious as originially assumed. These asphalt coverings would allow water, carrying dissolved de-icing salts, to seep through to the concrete interface, consequently scaling associated with de-icing salts would continue beneath the asphalt undetected. Because of this the British Columbia Department of Highways stopped using asphalt as a surfacing materials on concrete bridge decks. This paper looks at the method of resurfacing with thin concrete overlays bonded with neat cement paste. /RTAC/
