1 cubic yard of asphalt is approximately equal to 2 tons:
1 cubic yard ≈ 2 tons
The asphalt tonnage T is equal to the volume V in cubic yards times 2:
T = V × 2
To calculate the volume in cubic yards:
V (cubic yards) = (W × L × H) / 27
W = Width in feet
L = Length in feet
H = Thickness in feet (convert from inches by dividing by 12)
Combining these, the full formula is:
T = ((W × L × (H / 12)) / 27) × 2
Calculate the asphalt tonnage for an area with:
Width = 20 feet
Length = 100 feet
Thickness = 4 inches
Step 1: Convert thickness to feet
H = 4 / 12 = 0.333 feet
Step 2: Calculate volume in cubic yards
V = (20 × 100 × 0.333) / 27 = 24.69 cubic yards
Step 3: Calculate tonnage
T = 24.69 × 2 = 49.38 tons
