Raveling: aggregate becoming separated from the binder and loose on the road.Some of the issues that milling can remove include: Milling can also remove distresses from the surface, providing a better driving experience and/or longer roadway life. This reduces the impact that resurfacing has on the environment. įor asphalt surfaces the product of milling is reclaimed asphalt pavement (RAP), which can be recycled in the asphalt hot mix asphalt (pavement) by combining with new aggregate and asphalt cement (binder) or a recycling agent. Milling is widely used for pavement recycling today, where the pavement is removed and ground up to be used as the aggregate in new pavement. Recycling of the road surface is one of the main reasons for milling a road surface. There are a number of different reasons for milling a paved area instead of simply repaving over the existing surface. Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal. 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.
