Circular Area
Calculate aggregate for a circular area like a turnaround or fire pit base
Formula
Volume = L × W × D/12 ÷ 27 (cu yd) | Tons = Cu Yd × Density / 2000
Frequently Asked Questions
How deep should aggregate base be?
For driveways: 4-6 inches of compacted base. Patios: 4 inches. Walkways: 2-3 inches. Structural foundations: 6-12 inches depending on soil conditions. Always compact in lifts of no more than 4-6 inches at a time.
What is the difference between tons and cubic yards?
Cubic yards measure volume while tons measure weight. The conversion depends on the material density. One cubic yard of crushed limestone weighs approximately 1.35 tons (2,700 lbs). Always order by tons for accuracy since loose material can vary in volume.
