Quick answer
Calculate area, multiply by compacted thickness to find volume, then multiply by the appropriate asphalt density to estimate weight. Supplier and paving specifications control the final order.
Step by step
- Measure the paved area. Split irregular driveways into simple sections.
- Choose design thickness. Use project and base-condition guidance.
- Calculate volume. Area × thickness gives cubic feet or cubic yards.
- Convert to weight. Use the supplier's density or tonnage factor.
Formula or rule of thumb
Example
A 1,000 ft² area at 2 in compacted thickness has 166.7 ft³ of compacted volume before density conversion.
Common mistakes
Do not treat loose delivery volume as the same as compacted pavement volume, and do not choose thickness without considering base and traffic.
Planning note: product yields, installation methods, site conditions and local requirements can change the final quantity. Use the exact manufacturer or supplier information before purchasing.
FAQ
Is asphalt sold by cubic yard?
Many suppliers price or deliver asphalt by weight, commonly tons.
Does compaction matter?
Yes. Compacted thickness and delivered material volume are not identical.
Can this replace a paving estimate?
No. It is an early planning estimate only.
