Driveway Asphalt Calculator
Size a residential driveway in minutes — rectangle or total area, what's there now, and whether you need a base layer. Get surface and base tonnage, material cost, and the questions to ask before you hire.
Driveway Asphalt Calculator
Plan a residential driveway: choose the shape, what's there now, and whether you need a base layer. Get surface and base tonnage, material cost, and a contractor quote checklist.
Advanced settings — surface mix density
Defaults to the standard dense-graded hot-mix density of 145 lb/ft³ (≈109 lb per sq yd per inch). Adjust only if you know your mix design.
Estimated Results
Bare ground: plan to grade and compact the subgrade (and consider a geotextile on weak soils) before placing base. Poor subgrade is the most common cause of early cracking.
Assumptions
- Surface compacted density: 145 lb/ft³ — planning assumption, confirm with your plant's mix design.
- Waste allowance: 5% on top of net quantity.
- Quantities are for compacted layers only; subgrade preparation is not included.
Contractor quote checklist
- Confirm the mix type and its compacted density (lb/ft³ or kg/m³).
- Confirm the thickness design (surface and base) for your soil, climate and traffic.
- Ask about minimum orders and small-load fees.
- Get delivery cost and typical truck size.
- Ask whether grading, base preparation and compaction are included.
- Ask about a compaction guarantee or workmanship warranty.
- Confirm whether removal of the existing surface is included.
Planning estimate only. Final pavement design depends on soil, drainage, climate, traffic, local code, and contractor or engineer recommendations.
Typical US price ranges (planning reference): Material only (plant pickup) $40–$130 per short ton · Installed (typical residential) $5–$15 per sq ft
| Basis | Typical range | What it covers |
|---|---|---|
| Material only (plant pickup) | $40–$130 per short ton | Hot-mix asphalt at the plant before delivery; varies by region, mix design and order size. |
| Installed (typical residential) | $5–$15 per sq ft | Full installed consumer planning range; scope, removal, base prep and local conditions can move a real quote outside it. |

How a driveway is built up
A durable driveway is a system, not just a layer of blacktop. From the bottom up: a compacted subgrade (your native soil, graded to shed water), an optional aggregate base(compacted crushed stone that spreads load and drains), and theasphalt surface (typically 2–3 inches of hot mix for a passenger-car driveway).
This calculator lets you size the surface alone, or the surface plus a base layer, using separate densities for each. The surface uses a hot mix planning density (145 lb/ft³ by default); the base uses a typical compacted-aggregate value you can adjust to match your supplier's material.
What's there now matters
The existing surface changes your prep work and your bill:
- Bare ground — you'll need grading and compaction of the subgrade before anything goes down. Weak or wet soils may need a geotextile or deeper base.
- Gravel — an existing gravel drive can often be reworked and compacted as part of the base, cutting your new-base tonnage.
- Existing asphalt — decide between an overlay (if the base is sound) and full removal or milling. Removal adds demolition cost, which our asphalt cost calculator can fold into an installed estimate.
Ordering tips for small loads
A typical two-car driveway (roughly 600–800 sq ft at 3 inches) needs only about 11–15 tons of hot mix — and many plants have minimum orders or small-load fees below about 5 tons. The calculator flags a small load so you can ask about minimums and combine the pour with a neighbor or a second project.
