Recycling of Cass County I-80 Asphalt Concrete

Approximately 40,000 tons of slightly damaged asphalt concrete have been removed from Interstate 80 in Cass and stockpiled. Laboratory tests had indicated that this material had considerable value when upgraded with new aggregate and asphalt cement. This report documents the procedures used and results obtained on an experimental recycling project. It was demonstrated that present drum mixing-recycling equipment and procedures can be used to utilize this material with satisfactory results. Laboratory analyses of material components and mixtures were performed. These analyses indicate mixture can be produced that is uniform, stable, and very closely resembles mixture produced with all new material. Follow-up evaluations will be made to determine the effects of traffic and environment. Preliminary data indicate that plans should be made to incorporate the stockpiled material in projects near the stockpile site.
