Asphalt or cement milling is a process that removes defects from the pavement for safety and driveability reasons. Some of the road problems that milling can rectify are as follows:
Shoving: a washboard appearance opposite travel direction Ride quality: uneven road surface such as bumps or indentions Damage: caused by impact or fire Raveling: loose aggregate separates from binder and litters the road Bleeding: the binder rises to the surface of the road Rutting: occurrence of low spots in pavement usually along the wheel path
The process of milling asphalt or cement (also called cold planing or profiling) is the removal process of a paved surface. Surface milling or full-depth removal might be necessary based on the desired result and the level of deterioration experienced.
Milling generates the aggregate needed to create the new asphalt to be used in resurfacing or repair. This repurposing is better for the environment than full removal with new asphalt applied thereafter.
The Asphalt Recycling and Reclaiming Association has instituted classes of cold planing that the Federal Highway Administration has recognized. They are:
Class I - milling to remove surface irregularity Class II - milling to uniform depth as shown on plans Class III - same as class II with the addition of cross-slope Class IV - milling to the subgrade (full depth) Class V - milling to different depths at different areas
