Area × thickness × density, converted to the tons asphalt is sold and delivered by.
Unlike concrete (sold by volume) or gravel (also often by volume), asphalt is typically quoted and delivered by the ton — this calculator converts your area and thickness into an equivalent weight using a standard compacted density.
Many asphalt driveways use a thicker base layer plus a thinner top (wear) layer, applied separately for better durability — for a two-layer job, run this calculator once per layer with its own thickness.
Asphalt needed
9.667 tons
145 lb/ft³ is a typical compacted hot-mix asphalt density — check with your supplier for their specific mix.
