Calculated result

2.852 yd³ adjusted base

66.667 cu ft geometric base before allowances

3.85 tons at 100 lb/cu ft · about 154 × 50 lb bags

16.667 cu ft · 0.617 yd³ bedding volume at entered depth

200 sq ft project area

Show the working

1. Area = 20 × 10 = 200 sq ft.
2. Base volume = 200 × (4 ÷ 12) = 66.667 cu ft.
3. Adjusted base = 66.667 × 1.05 × 1.1 = 77 cu ft.
4. Weight = 77 × 100 = 7,700 lb = 3.85 tons.

Depth, compaction allowance and density are project/material inputs. Verify the pavement specification and supplier data before ordering.
