Existing Surface Preparation for Overlays -
Milling (also called grinding or cold planing) can be used to smooth an existing HMA pavement prior to HMA or PCC overlays. Rather than filling in low spots, as a leveling course does, milling removes the high points in an existing pavement to produce a relatively smooth surface. For HMA pavements, milling can help eliminate differential compaction problems.
