National Concrete Pavement Technology Center

Project description

The successful use of recycled concrete aggregate (RCA) in continuously reinforced concrete pavement (CRCP) in a field trial near Sealy, Texas, under Texas Department of Transportation (TxDOT) Project 0-7074 demonstrated the potential for increasing the sustainability of concrete paving while still achieving target performance. Based on the progress made under TxDOT 0-7074 and in line with ongoing TxDOT and Federal Highway Administration (FHWA) initiatives to reduce the carbon footprint of new concrete construction, this implementation project aims to build upon the previous trial near Sealy, while expanding the depth and breadth of the implementation to include significantly longer trial sections with a wider range of RCA replacement levels. The research team will facilitate implementation of the project findings by documenting the results of laboratory and field studies in the Research Report of the TxDOT Research Project "Increase the Allowable Content of Recycled Crushed Concrete Fine Aggregate in Class P Concrete." The Research Report will include specific recommendations on the use of recycled crushed concrete fine and coarse aggregate into Class P concrete.
