Description
The Virginia Department of Transportation used precast concrete panels inroundabout construction and roller compacted concrete in pavement construction. Roller-compacted concrete (RCC) is similar to regular concrete in strength andother hardened properties. It uses lower amounts of water so it is relativelystiffer than regular concrete when fresh and shrinks less when hardened. It is placed using asphalt pavers and roller, so it costs relatively less.RCC’s biggest advantage is that it can be placed and opened to traffic in ashort period of time, within 24 hours. Use of precast concrete panels enablesthe use of high-quality concrete, it facilitates expedited construction, andenables easy repairs – by replacing one panel at a time. Acceleratedconstruction can be very beneficial where extended traffic closure is notpractical or possible. Use of precast concrete panels can provide theopportunity to construct roundabouts in a short closure time thus creating lessdisruption to the traveling public.
