What Affects the Cost of a 20×20 Asphalt Driveway?
Thickness
Thickness has the biggest impact on both cost and longevity. Here's what each option costs for a 20×20:
- 2 inches — $1,400–$2,100. Minimum for light residential use. Not recommended for areas with harsh winters or heavy vehicles.
- 3 inches — $1,800–$2,800. Standard residential spec. Best balance of cost and longevity for most driveways.
- 4 inches — $2,200–$3,400. Heavy duty. Recommended for trucks, RVs, or areas with severe freeze-thaw cycles.
Old Driveway Removal
Replacing an existing concrete or asphalt surface adds $400–$1,200 to the project ($1–$3 per sq ft). Concrete costs more to remove than old asphalt. Always request this as a separate line item in your contractor quote.
Base Preparation
A solid sub-base determines how long your driveway lasts. Standard base prep adds $300–$600 for a 20×20. Soft, clay-heavy, or poorly drained soil requires additional stone and compaction work. Use our road base calculator to estimate sub-base material costs.
Contractor vs. DIY
Asphalt paving requires specialized equipment — a paver machine, roller compactor, and proximity to a hot mix plant. DIY is not practical. Your best approach is getting 3+ quotes from licensed local contractors and verifying they include proper base prep and correct thickness.
How Many Tons of Asphalt for a 20×20 Driveway?
Asphalt plants sell by the ton. Here's how many tons you'll need for a 20×20 driveway (400 sq ft) at different thicknesses, using standard 145 lbs/ft³ density:
| Thickness | Net Tons | With 10% Waste | Material Cost (~$110/ton) |
|---|---|---|---|
| 2 inches | 4.8 tons | 5.3 tons | ~$530 |
| 3 inches (standard) | 7.3 tons | 8.0 tons | ~$800 |
| 4 inches | 9.7 tons | 10.7 tons | ~$1,070 |

Tips for Getting the Best Price
- Get at least 3 written quotes. Prices vary 20–40% between contractors. Verify they include proper base prep and correct asphalt depth.
- Book in shoulder season. Spring (April–May) and fall (September–October) often cost 10–15% less than peak summer demand.
- Combine with a neighbor. Coordinating with a nearby neighbor can save both of you 10–15% on mobilization costs.
- Ask about recycled base. Using recycled asphalt millings or crushed concrete for the sub-base cuts base prep costs by 20–30%.

Frequently Asked Questions
How much does a 20×20 asphalt driveway cost?
A 20×20 asphalt driveway costs $1,800 to $2,800 installed in 2026, averaging around $2,200 nationally. This covers 400 sq ft at $4.50–$7 per sq ft including materials, labor, and standard base prep. The Northeast and West Coast run 20–35% higher; the Southeast is typically 10–15% lower.
Is a 20×20 driveway big enough for 2 cars?
Yes. A 20-foot wide driveway comfortably fits two standard cars side by side (10 ft per lane), with room to open doors. It's the most common double-car driveway size in the US. If you have large trucks or SUVs, consider 24 feet wide for extra comfort.
How long does a 20×20 asphalt driveway last?
A properly installed 20×20 asphalt driveway lasts 15–20 years with regular maintenance — sealing every 3–5 years ($100–$300) and prompt crack filling. With excellent care and a good sub-base, it can reach 25 years. Severe freeze-thaw climates or heavy truck traffic reduce lifespan.
What is the cheapest way to pave a 20×20 area?
The cheapest option is recycled asphalt millings at $500–$1,200 for a 20×20. They compact into a solid surface but lack the clean finish of new asphalt. For a permanent, professional-quality driveway, standard asphalt at $1,800–$2,800 is the most affordable. Concrete costs $3,200–$6,000; pavers $5,000–$12,000 for the same area.
How thick should a 20×20 asphalt driveway be?
3 inches of compacted hot mix asphalt is the standard recommendation. Never less than 2 inches — it will crack prematurely. For driveways supporting heavy vehicles (RVs, trucks, delivery), use 4 inches. Always install a compacted 4–6 inch gravel base beneath the asphalt layer.
