Development of a Mix Design Process for Cold-In-Place Rehabilitation Using Foamed Asphalt
The need to provide a safe, efficient, and cost-effective roadway system has led to a significant increase in the demand for ways to rehabilitate existing pavement. In the last several decades, asphalt recycling has grown to become the preferred method for restoring existing pavements. This study evaluates one of the recycling techniques used to rehabilitate pavement, called Cold In-Place Recycling (CIR). CIR is one of the fastest growing road rehabilitation techniques because it is quick and cost-effective. The document reports on the current practice of CIR with emulsion, presents a literature review of research on foamed asphalt, discusses the foaming experiment, presents a field data collection and compaction study, and describes the determination of mix design parameters for CIR with foamed asphalt.
