In a nutshell, cold in place recycling, is a process that rehabilitates a roadway to a depth between 2.5 and 5 inches by cold milling and mixing the mill tailings with asphalt stabilizing agents. Once mixed, the material is either picked up and placed with a conventional paving machine or blade graded and compacted to a specified density.
