How Many Tons of Asphalt in a Dump Truck (and How Much Driveway It Paves)

It depends on the truck. Ballpark figures: a small single-axle dump truck carries about 6 to 8 tons of hot mix asphalt, a tandem-axle truck carries roughly 12 to 16 tons, and a tri-axle carries around 18 to 22 tons. Bigger trucks and trailers can haul more where state weight laws allow. At a typical 2-inch compacted depth, one ton of asphalt covers about 80 square feet, so a 15-ton load paves roughly 1,200 square feet. Your local weight limits, the truck's empty weight, and the mix all shift these numbers.

How Many Tons of Asphalt in a Dump Truck, by Truck Type

These ranges are commonly cited planning figures. Actual legal loads vary by state, by truck, and by how the truck is set up.

Truck type	Typical asphalt load	Common use
Single-axle dump truck	About 6–8 tons	Small driveways, patching
Tandem-axle (10-wheeler)	About 12–16 tons	Most residential driveways
Tri-axle	About 18–22 tons	Larger driveways, small lots
Quad-axle or "super dump"	About 20–26 tons	Commercial work
Semi end-dump trailer	About 20–25+ tons	Large paving jobs

Why not just fill the bed? Asphalt is heavy. A truck usually hits its legal weight limit long before the bed is heaped full.

Why Weight, Not Volume, Sets the Load

For planning, we use 145 pounds per cubic foot for compacted hot mix, which is close to 2 tons per cubic yard, or roughly 110 to 115 pounds for every square yard at 1 inch deep. Loose in a truck bed, the same mix takes up a bit more room than it will after rolling.

Dump trucks have a gross weight limit set by axle count, axle spacing, and state law. Subtract the truck's empty weight from that limit, and what's left is how much asphalt it can legally carry. That's why two tandem trucks from different companies can carry different loads.

How Much Driveway One Load Covers

Here's the math, with clear assumptions.

Assumptions:

• Compacted asphalt: about 145 lb per cubic foot
• 1 ton = 2,000 lb
• No waste included

Coverage of one ton:

• At 2 inches: 2,000 ÷ (145 × 2/12) ≈ 83 sq ft
• At 3 inches: 2,000 ÷ (145 × 3/12) ≈ 55 sq ft

Put simply, each ton paves about 80 square feet at a 2-inch depth, and about 55 square feet at 3 inches.

Coverage by load (rounded, before waste):

Load	At 2 inches	At 3 inches
7 tons	~580 sq ft	~390 sq ft
14 tons	~1,160 sq ft	~770 sq ft
20 tons	~1,660 sq ft	~1,100 sq ft
22 tons	~1,820 sq ft	~1,210 sq ft

Contractors typically add a few percent for waste, uneven base, and edges.

Example: A Two-Car Driveway

Say your driveway is 20 feet wide and 50 feet long, paved 2 inches thick.

• Area: 20 × 50 = 1,000 sq ft
• Volume: 1,000 × (2 ÷ 12) ≈ 167 cubic feet
• Weight: 167 × 145 ≈ 24,200 lb, or about 12.1 tons
• With 5% extra: about 12.7 tons

That's one tandem-axle load. At 3 inches, you'd need about 18 tons plus extra, which is one tri-axle or two smaller trucks. Our how many tons of asphalt calculator runs this for any size.

Why Contractors Care About Truck Count

• Cooling time. Hot mix has to be placed and rolled before it cools too much. A crew plans trucks so asphalt arrives at a steady pace.
• Minimum loads. Plants and haulers often charge a minimum or a short-load fee for small orders.
• Driveway weight. A fully loaded tri-axle is extremely heavy. Many crews unload in the street or use smaller trucks to avoid damaging existing driveways, curbs, or buried lines.

What a Truckload Costs

Hot mix at the plant commonly runs somewhere around $90 to $130 per ton before delivery, though prices vary by region, season, mix type, and oil prices. Using that range as an illustration:

• A 7-ton single-axle load: roughly $630 to $910 in material
• A 14-ton tandem load: roughly $1,260 to $1,820
• A 20-ton tri-axle load: roughly $1,800 to $2,600

Delivery, short-load fees, and installation are extra. For a hired paving job, material is only one line on the bid. Our asphalt cost per ton page has more on pricing. Call local plants for current numbers.

Bottom Line on Tons of Asphalt in a Dump Truck

Most asphalt deliveries run from about 6 tons in a small truck to around 22 tons in a tri-axle, capped by weight limits rather than bed size. At 2 inches thick, each ton paves around 80 square feet, so a 15-ton load handles about 1,200 square feet before waste. Measure your driveway, run the math, and let the crew plan the trucks.
