Asphalt Milling

The key to implementing preventive maintenance techniques and maintaining a pavement management program is developing and maintaining an inventory of pavement condition and quantity. Proper pavement preservation is necessary to keep road quality high and life-cycle costs low.

Milling, which in essence is grinding the asphalt to a predetermined depth thereby making room for a new layer of asphalt to be paved into the milled area. Milling is performed by construction equipment called milling machines or cold planers. These machines use a large rotating drum to remove and grind the road surface. The millings or ground up asphalt particles are then hauled off site where they get recycled. The newly ground surface area is then layered with tack and a fresh smooth coat of asphalt is then applied.
