Cold-in-Place Recycling (CIR)

  1. 1
  2. 2

Cold-In-Place Recycling (CIR) is a roadway rehabilitation technique that recycles the existing pavement material in place without the application of heat like traditional hot-in-place recycling (HIR) the Town utilized in the past. CIR entails milling the top 2 inches to 5 inches of the existing pavement with a milling machine outfitted with a liquid asphalt injection system that creates a stabilized reclaimed asphalt pavement (RAP) material. The RAP material is then placed into a conventional paving machine and re-laid, rolled, and compacted. CIR requires a new wearing surface to be placed over the RAP material, which typically includes a traditional 1.5 inches to 2 inches hot mix asphalt overlay. This repair alternative is reserved for streets with a PCI from 50 to 65. We expect to extend a pavement's life by 15+ years with CIR.
