Frequently asked questions
How much asphalt do I need for a driveway? ›
A standard residential driveway uses a 2–3 inch surface course of asphalt. For a 50×12 ft driveway at 2.5 inches: 600 sq ft × (2.5/12) ft × 145 lb/ft³ × 1.18 compaction = about 10.6 tons. Most residential driveways require 6–15 tons of asphalt. Use the calculator above for your exact dimensions and depth.
What is the difference between surface course and base course? ›
A complete asphalt paving system has two layers: a compacted gravel base course (4–8 inches of crushed stone) that provides drainage and structural support, and the asphalt surface course (1.5–6 inches depending on traffic) that you drive on. For driveways replacing an existing surface, you may only need the surface course. New driveways on bare ground almost always need a properly compacted gravel base.
Why do I need a compaction factor? ›
Hot mix asphalt is delivered loose and compacted with a roller after spreading. Loose asphalt compacts approximately 15–25% in volume during rolling. This means you need to order more material than the finished volume. The standard 18% compaction factor is used for most residential and commercial hot mix asphalt (1 ton covers about 80 sq ft at 2 inches compacted depth).
How much does asphalt paving cost? ›
Asphalt material alone costs $80–$160 per ton delivered. A typical 600 sq ft driveway needs about 10 tons, or $800–$1,600 in materials. Installed cost (excavation, base, asphalt, labor) runs $3–$7 per square foot for residential driveways — so that same 600 sq ft driveway costs $1,800–$4,200 installed. Prices vary significantly by region, fuel costs, and project complexity.
About this asphalt calculator
This calculator computes asphalt tonnage using the standard paving formula: area × depth × density ÷ 2,000. It applies the compaction factor that accounts for loose material compressing during roller compaction, and optionally adds a gravel base course calculation. Six quick project presets auto-fill the recommended depth for common applications.
Asphalt vs. concrete for driveways
Asphalt driveways cost $3–$7/sq ft installed vs. $6–$12/sq ft for concrete. Asphalt needs resealing every 3–5 years but is easier and cheaper to repair. Concrete lasts 30–50 years with less maintenance but costs more upfront and cracks are more expensive to fix. In cold climates, asphalt handles freeze-thaw cycles better. In hot climates, asphalt can soften in extreme heat.
