This free calculator uses the industry-standard hot mix asphalt density of 145 lbs per cubic foot (2,322.7 kg/m³) to convert your project dimensions into tonnage and cost. Adjust the unit toggle for imperial or metric, and toggle the waste buffer to add a 10% allowance for compaction and trimming.
Units:
Imperial (ft / inches) Metric (m / cm)
Length (feet)
Width (feet)
Thickness (inches)

Measure the paved area in a straight rectangle when possible. For irregular shapes, divide the project into rectangles, calculate each one separately, and add the tonnages together. Thickness refers to the compacted finished depth.
