8 quick answers for common projects
Tonnage is hot mix asphalt at 145 lb/ft³ standard density with 7% waste allowance. Cost ranges are 2026 Q2 installed cost (material + labor + base prep). Adjust by region (Midwest +0%, Northeast +10-15%, West Coast +10-20%, South -5%).
| Project | Size | Depth | Tons | Truckloads | Installed cost |
|---|---|---|---|---|---|
| 1-car driveway, standard | 10 × 30 ft = 300 ft² | 2 in | 3.9 | 1 | $2,100 - $4,500 |
| 2-car driveway, standard | 20 × 40 ft = 800 ft² | 2 in | 10.3 | 1 | $5,600 - $12,000 |
| 3-car driveway, wide | 30 × 40 ft = 1,200 ft² | 2 in | 15.5 | 1 | $8,400 - $18,000 |
| Long rural driveway | 15 × 200 ft = 3,000 ft² | 2 in | 38.7 | 2 | $21,000 - $45,000 |
| RV / boat parking pad | 15 × 35 ft = 525 ft² | 3 in | 10.2 | 1 | $5,000 - $9,500 |
| Small office lot, 20 stalls | 5,400 ft² | 3 in | 105 | 5 | $16,000 - $38,000 |
| Strip retail lot, 50 stalls | 13,500 ft² | 3 in | 262 | 12 | $40,000 - $95,000 |
| Rural road, 1 lane-mile | 63,360 ft² | 4 in | 1,640 | 75 | $158,000 - $254,000 |
The 4 numbers you need before any calculator works
Every asphalt calculator on the internet (this one included) needs these four inputs. If you don’t have all four, the answer is a guess no matter how slick the tool looks.
- Length (in feet). Long dimension of the paved area, measured edge to edge.
- Width (in feet). Short dimension, also edge to edge.
- Depth (in inches). Compacted thickness of the asphalt. 2 inches for residential driveways. 3 inches for commercial parking. 4 inches for road or heavy-duty work. See the asphalt thickness calculator for the full design table.
- Density (in lb/ft³). Default 145 for hot mix asphalt. 142 for warm mix. 135 for cold mix. 120 for recycled millings. The right number changes the tonnage by 10-15%.
For non-rectangular shapes, calculate each section separately and add them up. The asphalt volume calculator handles circles, triangles and multi-section areas.
Why "how much asphalt" is the wrong first question
The tons answer is easy — it’s the area times depth times density math you saw above. The harder questions are the ones that determine whether you should be paving at all, and what you should be paving with.
The questions I ask before I quote a tonnage:
- How long do you expect this surface to last? 5 years vs 20 years changes the spec entirely.
- What kind of traffic? Passenger cars vs work trucks vs trash truck routes — the section design changes.
- What’s underneath right now? Existing pavement, gravel, or native soil — affects whether to mill, overlay or full-replace.
- What’s the drainage look like? A 2026 paved surface that ponds water won’t make it to 2030.
- What’s the budget reality? Sometimes the right answer is “wait and seal-coat the existing” rather than pour new.
If you’re mid-bid-comparison and just need to validate a contractor’s tonnage, the tons answer above is enough. If you’re trying to figure out what to do with a tired existing driveway, start with the driveway resurfacing calculator for the resurface-vs-replace decision instead.
From "how much" to "what should I order": 3 next steps
- Convert tons to plant order. The tons answer here is compacted in-place. Plants sell loose tonnage, which is about 5% lower. Order 5% more than the table says — or use the calculator pages with the waste field set to 7%, which already covers both.
- Schedule delivery. Tons answer doesn’t tell you how many trucks. Multiply by 0.045 (each ton requires roughly 22-25 minutes of paver feed time). The asphalt truckload calculator handles plant cycle math.
- Compare bids on the same tonnage. The most common mistake is comparing contractors’ quotes on price-per-square-foot without confirming they’re bidding the same depth and section. Always confirm tons of HMA and inches of base in writing.
How much asphalt FAQ
How much asphalt is in a typical truckload?
Tri-axle dump: 18-24 tons. Belly dump trailer: 28-34 tons. Live bottom trailer: 26-30 tons. Tandem-axle dump (smaller residential delivery): 15-19 tons. A typical 2-car driveway (10 tons) fits in one truck; a small commercial lot (250+ tons) takes 10-15 trucks over the course of the pour day.
How much does a yard of asphalt cost?
1 cubic yard of asphalt is about 1.96 US tons. At plant pricing of $100-150 per ton, that’s $196-294 per cubic yard for material only. Installed including labor and base prep runs $400-800 per cubic yard for residential, $600-1,200 for commercial parking lot. The full cubic yards to tons conversion has the breakdown.
How many tons in a square foot of asphalt?
About 0.012 tons (24 lb) per square foot at 2-inch compacted thickness. 0.018 tons at 3-inch. 0.024 tons at 4-inch. The conversion factor is 0.006 tons per ft² per inch of compacted depth, assuming standard 145 lb/ft³ HMA density. For UK tarmac in tonnes per m², see the tarmac calculator.
How accurate is this 30-second answer?
Within 5-10% for residential and small commercial projects when your dimensions are accurate. For larger commercial bids ($50,000+), refine through the project-specific calculator and verify against a paving contractor takeoff. For DOT-style highway work, follow the state DOT pay-quantity calc method exactly — the rules of thumb above are not adequate for highway bid work.
Do I need more asphalt for a curved driveway?
Slightly. Approximate a curved driveway as the straight-line area plus 5-10% for irregularity at the curve. A 12 × 100 ft curved drive that bends 30 degrees uses about 5% more material than 1,200 ft² rectangular math suggests. For precise calcs on irregular shapes, the asphalt volume calculator handles multi-section areas.
