Asphalt reference chart

Asphalt tonnage coverage chart

Look up the approximate paved area covered by one short ton or metric tonne at common compacted thicknesses.

At 145 lb/ft³, one short ton covers about 83 ft² at 2 inches before waste, or about 77 ft² with an 8% ordering allowance.

Thickness (in)	Area / short ton (ft²)	With 8% allowance (ft²)

Metric units

Scroll the table horizontally only if your screen is too narrow.

Thickness (mm)	Area / metric tonne (m²)	With 8% allowance (m²)
25	17.2	15.9
40	10.8	10
50	8.6	8
60	7.2	6.6
75	5.7	5.3
100	4.3	4

Coverage is calculated at 145 lb/ft³ (about 2,323 kg/m³). The allowance column divides theoretical coverage by 1.08; it is not an extra layer of asphalt.

Treat this as a fast planning lookup

Compacted thickness controls the result; do not enter loose lift thickness.
Replace the density and allowance with supplier values when preparing an order.
