What affects the price
Asphalt prices follow crude-oil prices because the binder is a petroleum product. Small residential jobs cost more per square foot because crews and equipment have a fixed mobilization cost.
The numbers on this page are estimates for planning. They take a national 2026 price range and scale it by Montana's overall price level (90.2 against a U.S. average of 100). Prices within the state can differ a lot between a metro area and a rural county.
