Evaluation of Recycled Portland Cement Concrete Pavement for Base Course and Gravel Cushion Material

Recyclable materials from construction and demolition operations were once disposed of in landfills. However, available landfill space continues to diminish. There is a need to use recyclable materials as recycled aggregate as a supplement to natural aggregates in order to conserve natural resources and to keep these products out of landfills. Recycled portland cement concrete has been successfully used throughout the world in pavement construction. These materials have been used in unbound base layers as well as replacement aggregates in both portland cement concrete and hot mix asphalt. The South Dakota Department of Transportation wishes to investigate the potential of using recycled concrete aggregate produced from rigid pavements. Therefore, the objectives of the project are to: (1) determine if recycled portland cement concrete pavements should be used as a base course and/or gravel cushion; (2) develop materials guidelines and specifications for construction pavements using recycled aggregates; and (3) develop laboratory and field material testing requirements for recycled concrete. Based upon the work conducted in this study, it was concluded that the recycled portland cement concrete pavements are available as an option for the construction of gravel cushion and aggregate base course layers. Recommendations were provided for material guidelines and construction of pavement layers using recycled concrete aggregates.
