Milling machines, also called pave-ment profilers, were first available in the mid-1970's. Fig. 13 shows a typical half-lane, rear-load milling machine of the 1970's. Today's milling machines like the front-load model shown in Fig. 14 are more productive and versatile than the early machines, and as a result, the cost of milling has been
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.
