Cold milling also ensures safety for users like skid resistance and better braking of vehicles.
What is Cold-in-place recycling and what are its advantages?
Cold-in-Place (CIR) recycling is a method of removing and reusing the existing asphalt surface. It involves grinding off the top 2 to 5 inches of the existing asphalt surface and mixing the crushed asphalt with an asphalt recycling agent, and placing it back down with a paver. Sometimes an additional module is included crushing this material …
