Asphalt milling, also called pavement milling, is an affordable and environmentally sustainable method for repairing small areas with asphalt, from driveways, roads, and busy parking lots. It is best for areas with widespread surface damage like cracking, raveling, or uneven slope.
Asphalt milling is a process of asphalt restoration where the top layer is removed to smooth the surface. This resurfacing of the asphalt helps prevent drainage issues and preserve the drainage patterns in the road. While also maintaining an even pavement height.
Most of the asphalt removed can be made into recycled asphalt material that can be used again, making asphalt milling an environmentally friendly solution. Asphalt milling is also economical and enables the restoration of a smaller pavement area rather than having to be demolished entirely and repaved.
How to Mill Asphalt
During the asphalt milling process, a large capacity grinder (or human-driven cold milling machine) is used to grind down the topmost layer of asphalt pavement, anywhere from a couple of inches to a full-depth removal. Asphalt milling has to happen before any overlaying or repaving can begin.
While traditional road demolition requires entirely ripping up damaged pavement and throwing it away. Asphalt milling helps repair only the damaged part of the road. The removed pavement is then used as aggregate in new hot-mix asphalt that can be used for uneven paved surfaces, fixing damaged roads after an accident, paving driveways, hardscape filler in landscaped gardens, and more. Any recycled asphalt (or millings) not used in road maintenance can then be sent to the roadbuilder’s maintenance depot or sold to traders in asphalt millings for resale.
After asphalt milling, new asphalt can be laid down without increasing the height of the roads. Therefore, preventing asphalt from getting too high — as having multiple overlays in structures adds too much height — which will create issues in the long run.
