Cold In-Place Recycling

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.

Benefits Include:

  • Cost Effective: 1/2 to 1/3 savings of conventional reconstruction
  • Traffic Flow: work is executed with minimal disturbance to traffic
  • Controls Reflective Cracking: mitigation or elimination of reflective cracking
  • Pavement Smoothness: improves pavement cross slope and profile by eliminating rough pavement conditions
  • Conserves Our Resources: energy is being conserved without the use of heat, and material hauling is minimized. Materials are conserved by using the existing pavement materials.
