Cold In-Place Recycling (CIR) is defined as an asphalt pavement rehabilitation technique that reuses existing pavement materials. CIR involves the processing and treatment with bituminous and/or chemical additives of the existing asphalt pavement without heat to produce a restored pavement layer. All work is done in place on the pavement being recycled. Utilizing the existing roadway materials will eliminate the need for transporting additional materials. The process will require a wearing surface placed over the newly recycled base course. A typical depth is normally 3 to 5 inches.
