Fast-Track Concrete Pavingby M. J. Knutson, American Concrete Pavement Assoc,

Abstract: Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge of farms, on top of aging state roads and at intersections in small towns. Unlike corn, which takes all summer to reach maturity, 'Fast Track' can produce a ride-ready road inside of 24 hours. Therefore, traffic re-routing is kept to a minimum, which under traditional paving operations can be an inconvenience that may last for weeks. 'Fast Track' is a combination of quick-setting mixes and coordinated construction teams. The pavements are constructed to last at least 30 years. Although quick setting concrete is routine in the precast and prestressed industry, it had not been attempted in large scale paving applications until 1985.
