Roller Compacted Concrete for Roadway Paving

The rising cost of oil and associated difficulties within the asphalt industry have been a cause for concern in the past year. In efforts to combat this problem, several states such as Florida, Alabama, Georgia, and Ohio have used alternative paving materials such as roller compacted concrete (RCC) to replace conventional concrete and/or asphalt on certain types of projects. RCC pavements have been used successfully for a number of years in ports, intermodal facilities, and other areas serving extreme loads; however, the use of RCC technology has only realty been applied to highways. Research is necessary to establish the features o f this product, as well as the economic benefits for the State of Arkansas. RCC is a zero slump concrete mixture. The RCC mixture utilizes the same materials as conventional concrete, but contains less paste. Thus, the mixture is stiff enough to support the weight of a roller during compaction. RCC pavements are constructed without forms, joints, steel reinforcing, or dowels, and do not required finishing. A number of methods for designing RCC mixes are currently available. To date, the industry has not adopted a standard method for these designs. The goals of this research project are to determine whether RCC can be utilized efficiently as an alternative roadway paving material within the State of Arkansas, identify any associated economic benefits, and to provide a standard RCC mix design procedure that can be implemented within the context of current Arkansas State Highway and Transportation Demand (AHTD) specifications.
