Cold In-Place Recycling reuses the pavement already in place through asphalt pulverization and heatless repurposing, which produces a rehabilitated, bituminous final pavement. Existing pavement materials are reused for the pavement resurface, resulting in a distress-free, rejuvenated and structurally sound final product. CIR is considered a green construction approach, and has environmental advantages that include eliminating old asphalt disposal, lowering energy and raw material consumption, and reducing overall transportation costs.

 

Cold In-Place Recycling is a proven method of pavement rehabilitation, used for diverse applications such as low-volume county roads and interstate highways. An overlay of hot mix asphalt is typically applied over CIR surfaces that anticipate high-traffic volumes, or when additional structural strength is required. CIR pavement can be surfaced with microsurface, cape seal or bituminous surface treatment.

 

Benefits of Cold In-Place Recycling (CIR)

• Long-term pavement performance is improved with less maintenance
• Controls reflective cracking
• Work is performed with minimal traffic disruption
• Cost effective
• Conserves raw materials
• Conserves energy
• Reduces greenhouse gas emissions

The Cold In-Place Process Consists of:

• Pulverizing the existing asphalt pavement
• Adding a new asphalt binder material to the pulverized asphalt
• Mixing the materials
• Placing the newly mixed materials on the roadway
• Compacting the new roadway

Types of Cold In-Place Recycling:

• Asphalt emulsion (engineered or standard)
• Foamed asphalt
