• Abstract:
  This report describes a procedure that can be used by an engineer to design a recycled mixture using material salvaged from an asphalt concrete roadway that is a candidate for recycling. Techniques are included for directing a study of the distressed pavement to determine the causes of the distress that produced the need for rehabilitation. After the causes of distress have been determined, the engineer can evaluate the salvaged materials to determine (1) if softening agents are needed and (2) if virgin aggregate and asphalt should be added and, if so, how much. Also included are directions for preparing candidate mixtures as well as suggested minimum values for stability and engineering properties. Example plots and tables demonstrate the use of the technique.
