Asphalt milling, also known as cold planing, is a process used in the paving industry to remove and recycle the top layer of an existing asphalt surface. This process involves the use of a milling machine to grind and remove the surface layer of asphalt, which is then hauled away to be recycled or disposed of.
Milling is a highly efficient and cost-effective method of pavement rehabilitation. By removing the surface layer of asphalt, the pavement is left with a smooth and even surface, which can then be resurfaced with a new layer of asphalt. This process not only extends the life of the pavement but also improves its overall appearance.
One of the primary benefits of milling is its ability to recycle the removed asphalt material. The milled asphalt can be used to create new asphalt pavement or recycled into other construction materials. This not only saves on disposal costs but also helps to conserve natural resources.
Another benefit of milling is its ability to correct surface irregularities and level the pavement surface. This helps to improve ride quality and safety by reducing the risk of accidents and damage to vehicles.
Milling is also a highly precise process that allows for the removal of only the top layer of asphalt. This precision ensures that the underlying base layer of the pavement remains intact, which helps to maintain the structural integrity of the pavement.
In addition, milling is a relatively quick process that can be completed in a matter of hours or days, depending on the size and complexity of the project. This minimizes disruption to traffic and allows for faster completion of paving projects.
