Cold In-place Recycling.
No matter how bad a road condition may be, the material itself can still be useful. Cold In-place Recycling (CIR) takes existing asphalt pavement and recycles it in a cost-effective, long-lasting road rehabilitation technique.
Process
In one continuous operation, the top 2 to 5 inches of distressed asphalt are cold-milled to produce reclaimed asphalt pavement (RAP). The RAP is then mixed with strengthening additives and placed back onto the existing roadway.
Benefits
- Up to half the cost of traditional total reconstruction methods
- Reuses 100% of existing material and lowers greenhouse gas emissions by up to 90%
- Faster construction times compared with conventional reclamation or reconstruction
- Longer lasting than shallow mill-and-fill, and extends road life by 15 to 20 years
Consider Cold In-place Recycling when
you’re looking for a cost-effective, environmentally friendly way to repair a poor road with reduced traffic and neighborhood disruption.
“We tried Cold In-place Recycling using foamed asphalt with indus for the first time in 2017 and had a very positive experience. We used the CIR process plus a 1.5” HMA overlay to rehabilitate a very heavily traveled industrial park road in the city, and we were able to eliminate cracking distresses throughout the 4” to 5” thickness of the existing pavement. Even with structure adjustments and the HMA overlay, our total project cost was only slightly more than the city-wide average for 2” mill-and-fill paving in 2016.”
