SETTING A NEW STANDARD FOR QUALITY

The U.S. Route 219 Meyersdale Bypass in Comerset County, Pennsylvania, is one of the largest single-section highways ever built by the Pennsylvania Department of Transportation in western Pennsylvania. The project set a new standard for public-private partnering. In addition, it won the Project of the Year Award at the 1999 Pennsylvania Quality Initiative (PQI) Awards Program in June 1999 and the PQI Concrete Pavement and Environmental awards. The quality processes used throughout the project were as complicated as the project itself. Because of the amount of concrete required and the need to assure uniform quality, the contractor constructed onsite a Rex Model-S batch plant. In addition to portland cement and flyash, the concrete mix contained air entrainment and water reducer No. 22. This gave the contractor total control over the quality of the concrete. The field crews had radio contact with the batch plant during concrete placement and could request modifications to the concrete mix if needed.
