Cold In-Place Recycling

Overview

Learn about the benefits of Cold In-Place Recycling Treatments

The reach of recycling goes much further than just aluminum cans. Roadways can, and should, also be recycled. Cold In-Place Recycling (CIR) allows for 2-5 inches of the existing pavement to be pulverized into aggregate and mixed with a rejuvenating asphalt emulsion then reused in the resurfacing of the road.

CIR can extend the life of a roadway upwards of 10-15 years, at a small cost of $6.50 per square yard (which includes the cost of the required wearing coarse), making CIR one of the most cost-effective ways to completely resurface a road. The entire CIR process only takes a few hours, making it both cost effective and time efficient, as well as easier on the traveling public.

CIR should only be used in pavement that requires a major structural upgrade due to severe cracking, shoving or rutting.

When sourcing materials, Cold In-Place Recycling can be found under the nomenclature CIR-EE.

Best Practices

  • Create a sample of the mixture and process it for verification testing.
  • Verify pavement depth.
  • Confirm that sub grade issues do not cause pavement distresses. If they do, those issues must be addressed.
  • Use equipment that is functioning properly and is accurately calibrated.
  • A fog seal is typically required after the CIR process to maintain the integrity of the surface until a wearing course can be applied.
