(Photo 1) Construction crews began pouring concrete on the Rouchleau Park bridge on the Highway 53 project May 20. Workers used a loop belt truck-mounted conveyor system to get the concrete from the truck on the edge of the bridge out to the Rotec placing system and placed where needed. (Photo 2) Workers then smoothed the concrete with floats and brooms and ensured that all voids were filled inside the deck’s reinforcing bar. (Photo 3) Then workers applied an evaporation retarder to aid in concrete curing and misted the new concrete as necessary to ensure it had time to cure before it dried out. There were 29 workers taking part in the effort and they installed about 800 cubic yards of concrete. Photos by Tom Lund, MnDOT
