Cold Planing (CP), commonly referred to as milling or profiling, is the controlled removal of the surface of an existing pavement to the desired depth or cross-slope with specially designed equipment capable of removing portions of the pavement surface to the specified grade and/or cross-slope. CP can be used in excavation, reconstruction, rehabilitation and maintenance operations.
CP allows for removal of a controlled amount of material vs complete new construction. Creating and utilizing RAP means less need for new materials, reducing costs
Reuse of resources eliminates greenhouse gases from the production of those resources. Can be as high as 50-60%.
Saves up to 60% in HMA plant and 100% in other processes by creating RAP for the reuses of existing pavement materials.
Save time by keeping guard rails, overpasses, etc. at the same height in relation to roadway eliminating the need to adjust their height.
Extends the life of the pavement structure by correcting smoothness issues, drainage issues and removing some top down cracking and raveling.
Shoulder drop off
Removal of deteriorated, stripped or aged asphalt
Poor ride quality caused by swells, bumps, sags and depressions
Diminished curb reveal heights
Restores pavement smoothness
Corrects grade and cross-slope issues
Restores pavement surface friction
Serves as a surface or grade preparation for other maintenance/rehabilitation techniques
