What’s Usually Included?
A standard residential asphalt driveway installation typically includes:
- Site preparation
- Minor grading
- Aggregate base preparation (if needed)
- Hot Mix Asphalt (HMA) paving
- Machine compaction
- Basic edge finishing
- Job site cleanup
Some contractors charge separately for demolition, permit fees, or drainage improvements. Always ask for an itemized estimate before signing a contract.
Note: If one quote is much cheaper than the others, check whether excavation, disposal, or the gravel base has been excluded.
20×40 Asphalt Driveway Cost Per Square Foot
Most paving contractors price residential driveways by square footage, making it easy to estimate costs for an 800-square-foot project.
For a 20×40 asphalt driveway, the average installed price is $4 to $8 per square foot, including materials, labor, and standard installation. However, projects that require significant excavation, drainage work, or a thicker asphalt layer can exceed this range.
| Cost Per Sq Ft | Estimated Total Cost |
| $4 | $3,200 |
| $5 | $4,000 |
| $6 | $4,800 |
| $7 | $5,600 |
| $8 | $6,400 |
Why Does the Price Per Square Foot Change?
Several factors influence the installed cost per square foot, including:
- Asphalt thickness
- Aggregate base condition
- Subgrade stability
- Excavation requirements
- Grading and drainage
- Local labor rates
- Material availability
- Equipment accessibility
- Regional demand
For example, a flat driveway with a stable subgrade usually costs less than a sloped property that requires excavation, drainage improvements, and additional base material before paving.
Quick Tip: The cheapest price per square foot isn’t always the best value. Proper base preparation has a bigger impact on driveway lifespan than saving a few dollars during installation.
Average Cost by State
| State | Average Cost |
| Texas | $3,600–5,800 |
| Florida | $3,400–5,900 |
| California | $5,000–7,500 |
| New York | $5,200–7,800 |
| Illinois | $4,000–6,200 |
How Much Asphalt Is Needed for a 20×40 Driveway?
A 20×40 driveway covers 800 square feet, but the amount of asphalt required depends on the finished pavement thickness after compaction. Most residential driveways use 2.5 to 3 inches of compacted Hot Mix Asphalt (HMA), while heavier vehicles may require a thicker surface.
Estimated Asphalt Required
| Compacted Thickness | Approximate Asphalt Needed | Recommended For |
| 2 inches | 9–10 tons | Light vehicle traffic |
| 2.5 inches | 11–13 tons | Most residential homes |
| 3 inches | 14–15 tons | SUVs, pickups, multiple vehicles |
| 4 inches | 18–20 tons | RVs, trailers, heavy-duty use |
For most homeowners, 2.5 to 3 inches of compacted asphalt over a properly prepared aggregate base provides the best balance of durability and cost.
Quick Tip: A thicker asphalt layer won’t last longer if it’s installed on a weak or poorly compacted base.
How Much Does a 20-Ton Load of Asphalt Cost?
Many homeowners search for the price of a 20-ton load of asphalt, but this can be misleading.
In most parts of the U.S., 20 tons of Hot Mix Asphalt typically costs $2,000 to $3,600 for the material alone. This price doesn’t include labor, grading, transportation, paving equipment, or base preparation.
Most residential contractors also combine several nearby projects into one asphalt delivery, so your driveway usually isn’t paying for an entire truckload by itself.
Note: Material cost is only one part of the project. Installation quality has a much bigger impact on long-term value.

What Affects the Cost of a 20×40 Asphalt Driveway?
Two driveways with the same 800-square-foot size can have very different prices. That’s because contractors estimate costs based on site conditions, material requirements, labor, and installation complexity—not just square footage.
Below are the biggest factors that influence your final price.
1. Asphalt Thickness
The thicker the asphalt, the more material and labor the project requires.
- 2 inches: Light residential use
- 2.5 inches: Standard residential driveways
- 3 inches: Heavy daily traffic
- 4 inches: RVs and commercial-style use
Choosing the right thickness helps prevent premature cracking and extends pavement life.
2. Base Preparation
The aggregate base supports the asphalt above it. If the base is weak or uneven, the pavement can crack even when high-quality asphalt is used.
Contractors may need to:
- Remove unstable soil
- Install crushed stone
- Compact the base in layers
- Improve drainage
A properly compacted base improves load-bearing capacity, reduces movement, and helps the driveway last longer.
Quick Tip: Investing in a strong base usually provides a better return than paying for an extra inch of asphalt.
3. Site Preparation and Excavation
If the existing soil or driveway isn’t suitable, excavation may be necessary before paving begins.
Additional work may include:
- Removing old asphalt or concrete
- Excavating soft soil
- Importing new base material
- Regrading the site
The more preparation your property needs, the higher the total installation cost.
4.Drainage and Grading
Water is one of asphalt pavement’s biggest enemies.
Proper grading directs water away from the driveway, while effective drainage protects the subgrade and aggregate base from moisture damage.
- French drains
- Swales
- Catch basins
- Edge drains
- Culverts
Although these upgrades increase the initial cost, they often prevent expensive repairs later.
Note: Standing water is one of the leading causes of early asphalt failure.
5. Labor and Local Material Prices
Labor costs vary across the United States. Homeowners in large metropolitan areas often pay more because of higher wages and operating costs.
Material prices also change based on:
- Local asphalt supply
- Transportation distance
- Fuel prices
- Seasonal demand
As a result, identical driveways can receive different estimates in different states.
6. Accessibility
A driveway that’s easy for paving equipment to reach generally costs less to install.
Projects may become more expensive if contractors must work around:
- Narrow access points
- Steep slopes
- Landscaping
- Fences or retaining walls
Restricted access usually increases labor time and equipment costs.
7. Permits and Local Regulations
Some cities and counties require permits before a driveway is installed or replaced.
Permit requirements vary depending on:
- Property location
- Driveway expansion
- Curb modifications
- Drainage changes
Ask your contractor whether permit fees are included in the estimate.
8. Typical Cost Breakdown
Understanding where your money goes makes it easier to compare contractor quotes.
| Cost Category | Typical Share |
| Hot Mix Asphalt | 25–35% |
| Labor | 25–35% |
| Aggregate Base & Materials | 10–20% |
| Excavation & Grading | 5–15% |
| Equipment | 5–10% |
| Removal & Disposal | 3–10% |
| Contractor Overhead & Profit | 10–20% |
These percentages vary depending on your property’s condition and the amount of preparation required before paving.
Quick Tip: Ask for an itemized quote. It helps you compare contractors fairly and identify hidden costs before work begins.

Hidden Costs Homeowners Often Miss
Many online estimates focus only on asphalt and labor. However, several additional expenses can increase your final project cost.
1. Driveway Removal
Replacing an old asphalt or concrete driveway usually requires demolition, hauling, and disposal.
2. Drainage Improvements
If water doesn’t drain properly, contractors may recommend French drains, catch basins, or additional grading.
3. Extra Excavation
Soft soil or poor subgrade conditions may require deeper excavation and additional aggregate base before paving.
4. Permit Fees
Some cities require permits for driveway replacement, expansion, or curb modifications.
5. Transportation Charges
Projects located far from an asphalt plant may have higher fuel and delivery costs.
6. Minimum Load Fees
Small residential jobs sometimes include minimum-load charges from the asphalt supplier.
Quick Tip: Ask whether your estimate includes demolition, permits, disposal, and cleanup to avoid unexpected charges
How to Save Money Without Sacrificing Quality
Saving money doesn’t mean hiring the cheapest contractor. The goal is to get the best long-term value for your investment.
Compare Multiple Quotes
Request at least three detailed estimates from reputable paving contractors.
Compare:
- Asphalt thickness
- Base preparation
- Drainage work
- Warranty
- Cleanup
- Final price
Keep a Good Existing Base
If your aggregate base is stable, your contractor may be able to reuse it instead of rebuilding the entire foundation.
