Hot-in-place recycling (HIR) is a method for rehabilitation of asphalt pavements. Potential for cost savings and resource preservation are high because existing pavement materials are processed on-site, with only the addition of small amounts of recycling agent. The Oregon Department of Transportation (ODOT) constructed HIR projects in 1992 and 1993. In September 1992, ODOT contracted with Oregon State University (OSU) to evaluate the HIR projects, synthesize existing information on HIR, and develop guidelines for HIR use. This report summarizes the information developed during the study: Construction equipment used on ODOT HIR projects is discussed; Field data from six HIR projects are presented; Results of a limited laboratory investigation of HIR are presented; Proper project selection was found to be extremely critical to HIR success. A selection procedure is presented; Based on information from the field studies and a limited laboratory testing program, a recommended mix design procedure is presented. This report is in two volumes. Volume I includes the body of the report, Volume II includes the appendices.
