Asphalt millings cost $10 to $20 per ton, while hot-mix liquid (HMA) asphalt prices are $40 to $80 per ton. Recycled asphalt is eco-friendly and easier to install. New asphalt is heavier, contains more oil, and is harder to install, but is more durable and lasts longer. Both require compacting and sealcoating.

For more information about how to calculate the metal value of a deposit as a whole, I recommend you to read the mineral deposit value page too.

Costs are synthesized for output ranging from 40 to 100 percent of capacity. As operations approach capacity, there is increased utilization of labor, yielding a lower labor cost per ton of output. Manhour requirements for all models range from a low of .24 manhour per ton in the most efficient operation to 1.33 manhours in the least efficient.
