Prices are national planning averages. Asphalt is tied to crude oil and freight costs, so your local quote can land well outside this range. Always confirm with a paving contractor before budgeting.

What is warm mix asphalt?
Warm mix asphalt (WMA) uses additives or foaming to produce and place at 50-100°F lower than hot mix. It hauls further, extends the paving season and cuts plant emissions.
Compacted density runs slightly lower than HMA at about 142 lb/ft³.
Longer workable window means better compaction on jobs far from the plant.
How the quantity is calculated
Tons = area (sq ft) × thickness (in) ÷ 12 × 142 ÷ 2,000. Cubic yards ignore density entirely: area × thickness ÷ 12 ÷ 27. Suppliers quote warm mix asphalt by the ton in most of the US, so tonnage is the number you order against.
Add a waste allowance of 5-10%. Uneven subgrade, spillage at the truck and the extra material a screed carries on the first pass all come out of your order, not the supplier's.
Typical installed cost for warm mix asphalt
Installed pricing runs roughly $7.00 to $15.00 per square foot nationally for long-haul jobs, cool-weather paving and night work. Small jobs carry a mobilisation minimum — most contractors will not roll a crew and a roller for under about $2,500.
