The aggregates contained in the old pavement can be crushed into smaller pieces in the milling operation (aggregate breakdown). Particle agglomeration increases the risk of insufficient moisture stability and fatigue resistance of the recycled asphalt mixture; aggregate breakdown often prevents the use of a higher RAP content in the new mixture.

Use a milling machine to grind up the top layer of asphalt, adjusting to the depth you need, depending on your project and how damaged the asphalt is. Put asphalt millings into a dump truck to be reused. The crushed asphalt can be as useful of an aggregate as concrete, gravel, or fresh asphalt in resurfacing.
