EVALUATION OF RECYCLED HOT MIX ASPHALT CONCRETE ON ROUTE 220

This report describes the performance of an approximately 8-mi. section of roadway on which the top two layers of asphalt concrete were milled, recycled through a conventional asphalt batch plant, and relaid. The recycled mix consisted of about 40% recycled material, 60% virgin aggregate, and 3.0% AC-5 asphalt cement. The project was accomplished with little difficulty and proved once again that recycling is an economical, feasible process. Over the 3 years the mix has been in service it has given very good performance and has provided impetus for the adoption in Virginia of a specification that allows a contractor to use as much as 25% recycle material in his hot mix production at his option.
