A 2-car asphalt driveway covers the same footprint as its concrete cousin: about 20 by 24 feet, or the 480 square feet loaded above. The material is where the price splits. At the example rates on this site, the asphalt number lands at half the concrete number for the same slab, which is why asphalt keeps winning on upfront cost.
The math at the example rates
| Thickness | Example rate | 480 sq ft comes to |
|---|---|---|
| 2 inches | $4.50 / sq ft | $2,160 |
| 3 inches | $6 / sq ft | $2,880 |
For reference, the same 480 square feet at the example broom-finish concrete rate of $9 comes to $4,320. All of these are example rates, not market data. If you are weighing the two materials, concrete vs asphalt for a driveway covers the trade-offs beyond the install price.
The base decides how long it lasts
Asphalt is a flexible pavement. It takes its strength from the compacted gravel base underneath, not from the black layer you see. A driveway paved over soft or poorly drained ground will rut, alligator, and crumble no matter how good the mix was. Paved over a solid, well-compacted base, the same asphalt behaves for years.
That is why base work shows up in quotes as its own line. At the example add-ons, extra grading and base work runs $1.50 per square foot, which is $720 on this driveway, and removing an old asphalt surface first runs $2 per square foot, another $960. A paver who insists on fixing the base before laying mix is not padding the bill. He is the one you want.
Thickness is about what parks on it
Two inches of asphalt handles cars. If a boat trailer, RV, or work truck lives on this driveway, the step up to 3 inches buys real durability at the edges and under the tires, and at the example rates it costs $720 more on 480 square feet. Edges are the weak point of any asphalt driveway, so keep wheels off the outer few inches or ask about edge support.
