Abstract

To further Iowa's development of asphalt recycling technology, this study sought to explore technically sound and more effective ways to identify the minimum Cold In-pace Recycling (CIR) properties necessary to permit placement of HMA overlay or chip seal. This research effort focused on procedures to minimize CIR exposure time while preserving the potential for a successful investment. This meant the procedures had to minimize the risk of CIR layer and HMA damage. One of the procedures researched was the moisture loss index of the CIR layer under limited laboratory and field conditions . The research sought to develop a better analysis tool that the industry and owner agencies can apply to monitor the CIR layer in preparation for timely placement of the wearing surface.
