Calculation Mechanics: Aggregate & Tonnage
Formulas adhere to ASTM standards, ACI 318 guidelines, and standard construction estimating practice.
Step-by-Step Derivation Breakdown:
- 1Surface area: 50 ft × 10 ft = 500 square feet.
- 2Raw cubic feet: 500 sq ft × 0.333 ft = 166.67 cu ft.
- 3Divide by 27: 166.67 ÷ 27 = 6.17 loose cubic yards.
- 4Apply 15% compaction settling factor = 7.1 compacted cubic yards.
- 5Calculate tonnage based on 2950 lbs/yd³ density: (7.1 × 2950) ÷ 2,000 lbs = 11.36 tons.
- 6Dump truck trips: Tri-axle dump trucks can legally haul ~10-12 yards or 15 tons max per highway axle weight limits = 1 load(s).
Field Inspection & Trade Best Practices
- Subgrade preparation: Excavate topsoil down to solid subsoil clay/rock before placing base aggregate.
- Geotextile fabric: Never skip geotextile underlayment on driveways or heavy parking; stone will migrate downward without it.
- Lifts and tamping: Place crusher run in maximum 3-inch to 4-inch lifts and compact each lift with a vibratory roller.

Frequently Asked Aggregate & Driveway Questions
How do I calculate gravel for a driveway?
Multiply length (ft) × width (ft) × depth (inches ÷ 12) to get cubic feet, then divide by 27 to get loose cubic yards. Add a 15% compaction factor to ensure adequate depth after vehicle rolling. To get tons, multiply cubic yards by 1.4.
How many tons of gravel fit in a dump truck?
A standard tri-axle dump truck carries between 10 and 12 cubic yards of gravel, or a maximum legal highway road weight of roughly 14 to 16 tons.
What is the best gravel for a driveway base?
Crusher Run (also known as Dense Grade Aggregate / DGA or 21A) is the gold standard for driveway bases. It contains a blend of 3/4-inch crushed rock down to stone dust that interlocks into a rock-solid, concrete-like surface when rolled.
