Asphalt Calculator — Tons Needed for Driveways & Parking
Estimate compacted asphalt tonnage from length, width, depth, and density, then add a matching gravel sub-base takeoff for order planning.
Formula: tons = (length × width × depth/12 × density) ÷ 2,000.
Common planning inputs
- Residential driveways often use about 2 inches of compacted asphalt.
- Roads and heavy traffic sections commonly start around 4 inches or more.
- Typical installed pricing often lands near $100–$200 per ton depending on market and haul distance.
Sub-base conversion
Gravel base volume is converted to tons at 1.4 tons per cubic yard for a quick order estimate. Always verify density with your supplier before purchasing.
Frequently Asked Questions
Why does the calculator show loose cubic yards?
Compacted asphalt is denser than loose material in the truck. Dividing by 0.85 gives a planning estimate for loose cubic yards before compaction.
How many truck loads do I need?
This tool assumes a standard 10-ton asphalt truck. Large projects may use different truck sizes, so confirm with your plant or paving subcontractor.
Should I include a gravel sub-base?
Most paving sections need a stable base. The sub-base field helps you estimate gravel depth and tonnage alongside the asphalt order.
