Abstract	After over forty years in service, the Columbia River Bridge at Revelstoke, British Columbia needed a comprehensive rehabilitation of the bridge superstructure, including the deck. A bridge-deck-overlay system that would provide a nominal 30-year service life with minimal maintenance was specified. This article describes the overlay mix design, construction process, and quality control for the bridge-deck-overlay. A steel fiber-reinforced, silica fume-modified concrete was used for the bridge deck overlay. The concrete was dry-bagged, which enabled close quality control. The resulting concrete displayed suitable slump retention for placement by the selected screed. A sand/cement slurry bonding system was used between the prepared bridge deck and overlay. After one year of service, the deck was evaluated and found to be free of defects and damage.
