How do I calculate how much asphalt I need?

Multiply length by width in feet by depth in feet (depth in inches divided by 12), then multiply by 145 lbs per cubic foot, divide by 2000 to get tons, and add 10 percent for compaction. For a 60x20 ft driveway at 2 inches depth, that is approximately 16 tons.

How much does an asphalt driveway cost?

Asphalt driveway installation costs $3 to $10 per square foot installed in 2026. A typical single-car driveway costs $1,900 to $4,800 and a double-car driveway runs $2,900 to $7,200.

What is the density of asphalt?

Standard compacted hot mix asphalt has a density of 145 lbs per cubic foot, equal to approximately 2,025 lbs per cubic yard or about 1 ton per cubic yard after compaction. Asphalt millings are lighter at approximately 110 lbs per cubic foot.

How many tons of asphalt are in a cubic yard?

One cubic yard of compacted hot mix asphalt weighs approximately 2.025 tons. For asphalt millings, use 1.48 tons per cubic yard.

How much do asphalt millings cost?

Asphalt millings cost $10 to $40 per ton delivered, compared to $80 to $130 per ton for new hot mix. Total installed cost for a millings driveway is typically $1 to $3 per square foot.

How thick should an asphalt driveway be?

The recommended thickness is 2 to 3 inches of compacted asphalt over a properly prepared base for residential driveways. Commercial driveways and parking lots typically use 3 to 4 inches.

How to Calculate Asphalt Tonnage

The exact formula paving contractors use to order the right amount of asphalt — no over-ordering, no running short.

The asphalt tonnage formula

Asphalt is ordered by the ton, but projects are measured in square feet and inches of depth. The conversion uses the density of compacted hot mix asphalt: 145 lbs per cubic foot (approximately 2 tons per cubic yard).

Asphalt tonnage formula

// Step 1: Volume in cubic feet cu ft = length(ft) × width(ft) × depth(ft) // depth(ft) = depth(in) ÷ 12 // Step 2: Weight in pounds lbs = cu ft × 145 // Step 3: Convert to tons + waste tons = (lbs ÷ 2000) × waste_factor

Example: A 60 ft × 20 ft driveway at 2" depth:
60 × 20 × (2/12) = 200 cu ft
200 × 145 = 29,000 lbs
29,000 ÷ 2,000 = 14.5 tons × 1.10 = 15.95 tons → order 16 tons

Thickness guide by project type

1"–1.5": Overlay / resurfacing over sound existing asphalt
2": Standard residential driveway (most common)
2.5"–3": Heavy residential, RV pads, heavy vehicle access
3"–4": Commercial parking lots and driveways
4"–6": Roads, high-traffic commercial, base course

⚠ Base prep matters Asphalt thickness refers only to the asphalt layer. A proper driveway also requires 4"–8" of compacted gravel base underneath. Without a solid base, even thick asphalt will crack and fail within 3–5 years.

Tons to cubic yards conversion

Since asphalt is sometimes sold by the cubic yard (especially millings), the conversion is: 1 cubic yard of compacted hot mix = approximately 2.025 tons. For millings (RAP), the density is lower — approximately 1.48 tons per cubic yard.

📐

Measure accurately

For irregular driveways, divide into rectangles and add the areas together. Include aprons, turnarounds, and any widened sections — contractors charge for the full area.

➕

Always add 10% waste

Asphalt compacts 10–15% during roller compaction. Order at least 10% extra. Running short mid-pour means a cold joint — a visible seam that's a future failure point.

🌡️

Temperature matters

Hot mix asphalt must be laid above 50°F ambient temperature. Cold weather reduces the working time dramatically. Millings and cold mix can be placed year-round.

Driveway size	Sq ft	Tons (2")	New install cost	Overlay cost	Remove & replace
Single car, short	200 sq ft	~3.2 tons	$800–$2,000	$500–$1,200	$1,200–$2,800
Single car, standard	480 sq ft	~7.7 tons	$1,920–$4,800	$1,200–$2,880	$2,880–$6,720
Double car, standard	720 sq ft	~11.5 tons	$2,880–$7,200	$1,800–$4,320	$4,320–$10,080
Long driveway (200 ft)	2,400 sq ft	~38.4 tons	$9,600–$24,000	$6,000–$14,400	$14,400–$33,600
Parking lot (small)	5,000 sq ft	~80 tons	$17,500–$35,000	$10,000–$20,000	$25,000–$50,000

What affects asphalt driveway cost?

Project size: Larger projects have lower cost per sq ft — contractors spread mobilization costs over more area
Thickness: Each additional inch adds approximately $1–$2/sq ft to installed cost
Base preparation: Poor existing soil or gravel adds $2–$5/sq ft for sub-base work
Removal of existing: Demo and haul-away adds $1–$3/sq ft
Edging and drainage: Curbing, borders, and drain installation are additional
Region: Northeast and West Coast labor rates run 20–40% above national average
Asphalt price: Tied to crude oil prices — can fluctuate 20–30% year to year

Asphalt millings vs. new asphalt

Asphalt millings (also called RAP — Reclaimed Asphalt Pavement) are the ground-up material from old asphalt roads. They cost $10–$40 per ton vs. $80–$130/ton for new hot mix — a 60–80% savings on material.

Millings compact well and are excellent for:

Rural driveways and farm lanes
Temporary or budget driveways
Base layer under new asphalt
Parking areas and equipment pads

✅ Millings tip Millings actually bond together over time as residual bitumen re-activates in heat. A properly installed millings driveway can last 10–15 years with no maintenance — and can be recycled again when replaced.

FAQ

Frequently asked questions

Common questions about asphalt tonnage, driveway costs, and millings.

Multiply your area (length × width in feet) by the depth in feet (depth in inches ÷ 12), then multiply by 145 (lbs per cubic foot), then divide by 2,000 to get tons. Add 10% for compaction waste. For example: a 60×20 ft driveway at 2" depth = 60 × 20 × 0.167 × 145 ÷ 2,000 × 1.10 = 16 tons. Use the calculator above for instant results without doing the math.

At standard 2" depth, asphalt weighs approximately 0.053 tons per square foot (including 10% waste). So 100 sq ft requires about 5.3 tons, 500 sq ft requires 26.5 tons, and 1,000 sq ft requires 53 tons. At 3" depth, multiply by 1.5 — so 1,000 sq ft needs approximately 79 tons.

Asphalt driveway installation costs $3–$10 per square foot installed in 2026, with a national average around $4–$7/sq ft for a standard new driveway. A typical single-car driveway (480 sq ft) costs $1,900–$4,800. A standard double-car driveway (720 sq ft) runs $2,900–$7,200. These figures include materials, grading, and labor for hot mix asphalt at 2" depth. Full replacement (remove + install new) costs 40–60% more than a new installation on bare ground.

Standard compacted hot mix asphalt (HMA) has a density of 140–148 lbs per cubic foot, with 145 lb/cu ft used as the industry standard for calculations. This equals approximately 2,025 lbs per cubic yard or roughly 1 ton per cubic yard after compaction. Asphalt millings (RAP) are lighter at approximately 110 lbs per cubic foot due to less dense packing. The calculator uses 145 lb/cu ft by default but allows you to adjust.

One cubic yard of compacted hot mix asphalt weighs approximately 2.025 tons (at 145 lb/cu ft density). So to convert cubic yards to tons, multiply by 2.025. To convert tons to cubic yards, divide by 2.025. For asphalt millings (RAP), use 1.48 tons per cubic yard instead, since millings are less dense at approximately 110 lb/cu ft.

Hot mix asphalt costs $80–$130 per ton in 2026 for the material only, with a national average around $100/ton. Asphalt pricing is heavily tied to crude oil prices and fluctuates seasonally — prices are typically higher in spring/summer (peak paving season) and lower in fall. Regional variation is significant: Southern states often have lower costs ($75–$95/ton) while Northeast and West Coast markets can reach $120–$150/ton. Always get current quotes from local asphalt plants.

Asphalt millings (RAP — Reclaimed Asphalt Pavement) cost $10–$40 per ton delivered, compared to $80–$130/ton for new hot mix. The total cost for a millings driveway including delivery and spreading typically runs $1–$3 per square foot, vs. $4–$7/sq ft for new asphalt. Millings are sourced from road milling operations — availability and price vary significantly by region. Some areas offer free millings if you arrange pickup.

The recommended asphalt driveway thickness for residential use is 2"–3" of compacted asphalt over a properly prepared base. 2" is the minimum for light vehicle traffic (passenger cars). 3" is recommended for heavier vehicles, RVs, or climates with significant freeze-thaw cycles. Commercial driveways and parking lots typically use 3"–4". Thickness alone doesn't guarantee longevity — a solid compacted gravel base (4"–8") is equally important.

Yes — for the right situation. Asphalt millings are an excellent low-cost option for rural driveways, farm lanes, temporary access roads, and parking areas. They compact well, drain adequately, and the residual bitumen causes them to bind together over time in hot weather. They're not ideal for urban driveways in HOA communities (appearance) or areas with heavy freeze-thaw cycles (can become loose). Properly installed millings driveway can last 10–15 years at a fraction of the cost of new asphalt.

To convert asphalt tons to cubic yards: divide tons by 2.025. To convert cubic yards to tons: multiply by 2.025. This is based on the standard density of 145 lb/cu ft for hot mix asphalt. For millings (RAP), use a factor of 1.48 instead (110 lb/cu ft). Example: 20 tons of hot mix = 20 ÷ 2.025 = 9.9 cubic yards. The tonnage calculator above shows both tons and cubic yards automatically.
