How asphalt tonnage is estimated
Volume equals area multiplied by compacted thickness. This calculator uses a planning density of 145 pounds per cubic foot and adds the selected waste allowance. Mix density and delivered quantity vary, so confirm the order with the paving supplier.
Driveway thickness
Residential asphalt thickness depends on soil, base preparation, climate, and vehicle loads. Ask a qualified local paving contractor to specify the base and compacted lift thickness for your site.
