Asphalt Driveway Cost Guide: Installation, Repair & Sealing

Asphalt Driveway Cost Per Square Foot

A new asphalt driveway typically costs $3–$7 per square foot installed, including excavation, gravel base, and asphalt surface. Concrete driveways cost more at $6–$12 per sq ft. For a standard single-car driveway (10×20 ft = 200 sq ft), expect to pay $600–$1,400 for asphalt. A two-car driveway (20×24 ft = 480 sq ft) runs $1,440–$3,360.

Most residential driveways fall between 400–800 sq ft. At $5/sqft average: a 600 sq ft driveway costs approximately $3,000 installed.

Asphalt Driveway Construction

A properly built asphalt driveway has two structural layers:

Aggregate base: 4–6 inches of compacted crushed stone (gravel). This layer provides stability and drainage. Skimping here causes premature cracking and rutting.
Asphalt surface course: 2–3 inches of hot mix asphalt, compacted with a roller. Residential driveways typically use 2 inches; high-traffic or heavy-vehicle areas use 3 inches.

Total depth from grade: 6–9 inches. This requires excavating and removing existing soil to create the proper depth before laying the base.

Asphalt vs. Concrete: Which Is Better?

Asphalt advantages: Lower upfront cost, faster to install, flexible — handles freeze-thaw cycles well without cracking, easier to repair
Asphalt disadvantages: Requires sealing every 3–5 years, can soften in extreme heat (>100°F), shorter lifespan (20–30 years)
Concrete advantages: Longer lifespan (30–40 years), less maintenance, doesn't soften in heat, better for hot climates
Concrete disadvantages: Higher cost ($6–12/sqft), more prone to cracking in freeze-thaw climates, harder to repair

Bottom line: In cold-winter climates (northern US, Canada), asphalt is generally the better choice due to flexibility. In hot, dry climates (Southwest), concrete's longevity and heat resistance make it preferable.

Maintenance: Sealing and Repair

Asphalt requires periodic maintenance to achieve its full lifespan:

Seal coating: Apply sealant every 3–5 years to protect against UV damage, water penetration, and oil spills. DIY cost: $50–$150. Professional sealing: $80–$250 for a standard driveway.
Crack filling: Fill cracks immediately when they appear using rubberized crack filler ($10–$20/tube). Small cracks become large cracks and then potholes if ignored.
Wait 6–12 months before applying the first sealcoat on a new driveway — the asphalt needs time to fully cure and off-gas oils.

Resurfacing vs. Replacement

If your existing asphalt is structurally sound but the surface is oxidized and worn, resurfacing (applying a new 1.5–2 inch asphalt layer over the existing) is much more economical than full replacement. Resurfacing costs $2–$4/sqft vs. $4–$7/sqft for full replacement. The key question: is the base layer intact? If the driveway has significant alligator cracking (looks like cracked mud), heaving, or major depressions, the base is compromised and resurfacing won't hold — replacement is necessary.

Frequently Asked Questions

How much does it cost to pave a 2-car driveway?

A typical 2-car asphalt driveway (20×24 ft = 480 sq ft) costs $1,500–$3,500 for a new installation. If you have a longer driveway to the street, measure the total length × width. At $4–$6/sqft all-in (excavation, base, asphalt, compaction), a 600 sq ft two-car driveway averages around $2,400–$3,600.

Is asphalt or concrete better for driveways?

In cold climates with freeze-thaw cycles, asphalt is generally better — it flexes rather than cracking under frost heave and costs less to install and repair. In hot climates, concrete is better — it doesn't soften in extreme heat and lasts longer with less maintenance. Both are valid choices; cost and climate are the primary deciding factors.

How long does an asphalt driveway last?

A properly installed asphalt driveway lasts 20–30 years with regular maintenance including sealing every 3–5 years and prompt crack repair. Neglected driveways without maintenance may deteriorate in 12–15 years. Climate matters too — extreme temperature swings accelerate wear. A well-maintained driveway in a moderate climate can last 30+ years.

When should I seal my asphalt driveway?

First sealing should wait 6–12 months after new asphalt installation. After that, reseal every 3–5 years. Signs it's time to seal: the driveway has faded from black to gray, water no longer beads on the surface, or small cracks are starting to appear. Seal on a dry day with temperatures above 50°F. Avoid sealing in direct hot sun or before rain.

How thick should an asphalt driveway be?

For residential driveways, 2–3 inches of compacted asphalt is standard. The more important layer is the compacted gravel base: 4–6 inches minimum, 8 inches in areas with poor soil or freeze-thaw conditions. Total depth from grade: 6–9 inches. If a contractor proposes only 1.5 inches of asphalt with minimal base, push back — that will fail prematurely.
