RURAL HOT MIX RECYCLING

Hot recycling is the transporting of salvaged existing asphalt pavement from its original location to a central asphalt plant site for processing. Rural roadways that are recycled may present different problems and needs than urban projects. Generally, with the type of asphalt pavement encountered in rural projects, technologists need to consider the variability of the salvaged material that is designed into a recycled mixture. During the past four years much has been done to develop recycled asphalt mix design procedures. These procedures are being time tested and will, by the nature of the technology, be revised continuously. Rural roads that are recycled may, due to their length and lower traffic volumes, dictate lower unit cost designs. Recently developed equipment allows the removal of the total existing pavement or variable thicknesses of the upper pavement surface for recycling. The Michigan Department of Transportation has hot recycled several rural roadway projects during the past three years. Two typical rural recycling projects--one using drum mix recycling, the other using batch plant recycling--are discussed, and information and data on cost and energy conservation are presented.
