What is Pavement Milling?

Pavement milling, or cold planning, 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 many different reasons for milling a paved area instead of simply repaving over the existing surface. Recycling of the surface is one of the main reasons for milling a road surface. Milling is widely used for pavement recycling today, where the pavement is removed and ground up to be used as the aggregate in new surface.
