Concrete milling is a process that strips layers of concrete from roads, bridges, parking lots, and other paved surfaces to create a smooth surface with plenty of grip. Even though concrete surfaces that have been milled are finished and level, they need maintenance over time, in order to make sure they're safe and well-cared for.
Pavement milling (cold planing, asphalt milling, or profiling) is the process of removing at least part of the surface of a paved area such as a road, bridge, or parking lot.Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal. There are a number of different reasons for milling a paved area instead of simply repaving …
