Abstract
This article presents a highway reconstruction project on Interstate 86 in southern Idaho that qualified its contractor for the National Asphalt Pavement Association's Sheldon G. Hayes award (a Quality in Construction Award), as part of the countrywide study by the National Cooperative Highway Research Program (NCHRP). The project used the cement-recycled asphalt base stabilization (CRABS) process, which provides longer life for not a lot more cost, and also allows savings on liquid asphalt and aggregate by recycling the old asphalt into the new pavement. Details of the paving project are included here.
