How much asphalt do I need for a 24×50 driveway?
A 24 × 50 ft driveway is 1200 square feet. Paved 3 inches thick, the standard for a new residential driveway, it takes 22.8 tons of hot-mix asphalt including 5 percent extra, over a 6 in gravel base of 36.7 tons (24.4 cubic yards). A 2 in overlay on existing pavement needs 15.2 tons; a 4 in driveway for trucks or an RV needs 30.5.

What it costs to pave a 24×50 driveway
Hot mix costs $100 to $200 a ton from the plant, so the 22.8 tons for this driveway is $2,284 to $4,568 in asphalt, plus $1,467 to $2,200 for the gravel base. Asphalt is not a do-it-yourself material, though: it arrives at 300 °F and must be spread and rolled within minutes, so the real number is the installed price. Contractors typically quote $7 to $13 per square foot for a new driveway with base, grading, and compaction, or $8,400 to $15,600 for 1200 square feet. A 2 in overlay on sound existing asphalt runs $3 to $5 per square foot, about $3,600 to $6,000. Get three quotes and ask each for the thickness in writing.
Overlay, resurface, or replace a 24×50 driveway?
- Sealcoat ($0.15 to $0.40 per square foot, $180 to $480) if the surface is gray and dry but not cracked. It is cosmetic protection, not a repair.
- Overlay 1.5 to 2 in of new asphalt over the old (15.2 tons) if the base is solid and cracks are minor. Expect 8 to 12 years.
- Replace when there are alligator cracks, potholes, or sinking spots. Those mean the base has failed and new asphalt on top will fail the same way within a few years.
- A concrete driveway of the same size would need about 16.3 cubic yards at 4 in; compare with the concrete calculator. Concrete costs more up front and lasts longer.
