Abstract:Cold in-place recycling (CIPR) is a continuous multi-step process in which the existing asphalt pavement is
recycled using specialized equipment that cold mills the asphaltic pavement and blends asphalt emulsion and
aggregate (if necessary) with the reclaimed material. The blended mix is then redeposited and compacted inplace.
Once cured, all CIPR projects are overlaid with a wearing surface. Although CIPR has been used in
many regions of New York, the comparative performance and life cycle costs of CIPR versus other
maintenance options have not been well established. This report presents a summary of the findings,
conclusions and recommendations of a comprehensive examination of CIPR use, field performance,
comparative life cycle costs and the life cycle environmental burden of CIPR versus alternative maintenance
options currently used in New York State. It includes a Best Practice Guideline and recommended mix design
and construction specifications. Supporting attachments are provided to support the summarized findings and
conclusions presented herein.
