Asphalt milling, also known as cold planing, is the removal or milling up of an asphalt surface to provide an improved surface for repaving or resurfacing. The amount of asphalt removed depends on the condition of the original surface and the intended use. It is a cost-effective and sustainable process that can be repeated as needed.
When is milling necessary?
Asphalt milling may be appropriate in instances of crackling and raveling. If the base is in good condition, full-depth reclamation is not needed. Asphalt milling will remove the topmost layers and then a new surface can be applied.
Asphalt milling can also be used to address specific issues with small sections of pavement. When the entire surface does not need to be resurfaced, the target area can be milled without disruption to the rest of the roadway.
What happens to the milled asphalt?
The milled asphalt can be re-used immediately or can be used as a source of income and recycled into new HMA.
