All American Asphalt — Complete US Asphalt Paving Guide for 2026
Asphalt is America's most popular paving material — used for 94% of the country's 2.7 million miles of paved roads and the vast majority of residential driveways and commercial parking lots. This guide covers American asphalt standards, regional pricing across all 50 states, how to select a qualified paving contractor, and the free calculators you need to plan any US paving project.

US Asphalt Standards and Specifications
AASHTO and Superpave
American asphalt is specified using AASHTO (American Association of State Highway and Transportation Officials) standards — the technical backbone of all US paving work from residential driveways to interstate highways. The Superpave (Superior Performing Asphalt Pavements) system, developed through a $150 million federal research program in the 1990s, transformed US asphalt specification by matching the binder to local climate conditions using the Performance Grade (PG) system, rather than applying a single national standard to all climates.
Performance Grade (PG) Explained
The PG grade specifies the temperature range a binder must perform within. The two numbers indicate the maximum and minimum pavement temperatures the binder is engineered for:
| PG Grade | US Application | States |
|---|---|---|
| PG 64-22 | Most common residential grade | Most of continental US |
| PG 76-22 | High-heat / high-traffic applications | AZ, NV, TX, inland CA |
| PG 58-28 | Cold climate — handles -28°C minimum | MN, WI, ME, MT, ND |
| PG 52-34 | Extreme cold — handles -34°C minimum | AK and far northern US |
For residential driveways, your contractor selects the appropriate PG grade for your region automatically — you do not need to specify this.
Density Standard
American hot mix asphalt is specified at 145 lbs/ft³ (2,323 kg/m³) for standard HMA — the density used in all US tonnage calculations and the standard built into our asphalt calculator and tonnage calculator, both following AASHTO standards.
American Asphalt Prices by Region (2026)
The single biggest driver of US asphalt cost variation is proximity to crude oil refineries (Gulf Coast states benefit most) and local labor market costs (Northeast and West Coast are highest):
| Region | Key States | HMA $/ton | Installed $/sqft |
|---|---|---|---|
| Northeast | NY, NJ, MA, CT, RI, ME, NH, VT | $110–$175 | $5.00–$9.00 |
| Mid-Atlantic | PA, MD, DE, DC, VA | $100–$155 | $4.50–$8.00 |
| Southeast | FL, GA, NC, SC, AL, MS | $85–$130 | $3.50–$6.00 |
| Midwest | OH, IN, IL, MI, WI, MN, IA, MO | $95–$150 | $4.00–$7.00 |
| Great Plains | KS, NE, SD, ND, OK | $90–$140 | $3.75–$6.50 |
| South Central | TX, AR, LA | $85–$135 | $3.50–$6.50 |
| Mountain West | CO, UT, WY, MT, ID | $100–$155 | $4.50–$8.00 |
| Southwest | AZ, NM, NV | $90–$145 | $4.00–$7.00 |
| West Coast | CA, OR, WA | $120–$180 | $5.50–$10.00 |
| Pacific | HI, AK | $150–$250 | $8.00–$15.00 |

American Asphalt Mix Types
Hot Mix Asphalt (HMA) — The American Standard
Produced at 275–325°F at one of America's 3,500+ asphalt plants, HMA is the gold standard for all permanent US paving — driveways, parking lots, local roads, and Interstate highways alike. The high production temperature ensures complete coating of aggregate particles and a dense, impermeable final product. Use our hot mix asphalt calculator to estimate tonnage for any HMA project.
Warm Mix Asphalt (WMA) — The Sustainable Alternative
Produced at 200–250°F using chemical additives or foaming technology that allow lower mixing temperatures without sacrificing performance. WMA adoption is growing rapidly across US state DOTs as sustainability mandates increase — it delivers similar field performance to HMA at 5–10% lower energy consumption and carbon footprint per ton produced. Some states now require WMA for certain project types.
Recycled Asphalt Pavement (RAP)
America recycles approximately 99% of all removed asphalt — the highest recycling rate of any material in the US by weight, ahead of aluminum, glass, and paper. RAP is incorporated into new HMA mixes at 15–50% by weight depending on specification, reducing virgin material consumption and lowering cost. RAP millings that aren't returned to the plant are often used directly as a surface material for driveways and rural roads. See our recycled asphalt calculator and the full asphalt millings guide.
Cold Mix Asphalt
Cold mix uses emulsified asphalt binder that allows mixing and application at ambient temperature. Used for emergency pothole patching and temporary repairs only — not suitable for permanent paving installations. Widely available at US hardware and home improvement retailers. Use our pothole repair cost calculator before deciding between DIY cold patch and professional permanent repair.
How to Choose an American Asphalt Contractor
Required Credentials (Vary by State)
Most US states require a contractor license for paving work exceeding a certain dollar threshold. Always verify these four credentials before signing any contract:
- State contractor license — check your state's contractor licensing board website
- General liability insurance — minimum $1 million; request a certificate of insurance
- Workers' compensation coverage — mandatory in most states; without it you can be liable for injuries on your property
- Local business registration — an established local presence is a strong indicator of a legitimate contractor
What a Quality US Asphalt Contract Should Include
Every legitimate American paving contractor should provide a written contract specifying: exact pavement thickness (in inches), mix type and PG grade, base preparation scope (grading, existing base condition), area measurements in square feet, project timeline, warranty terms (minimum 1-year workmanship; 5 years is preferred), and a payment schedule. Never pay the full project amount upfront — a reasonable deposit is 25–33% in most states.
✅ Regional Contractor Booking Tips
- Northeast & Mid-Atlantic: Book in February–March — summer backlog is severe
- Southeast & Southwest: Year-round season means more availability and competitive pricing
- Mountain & Plains: Weather windows are short — lock in your contractor by April
- California: Verify CSLB Class C-12 license (specialty asphalt/concrete) specifically

Frequently Asked Questions
What is the most common asphalt used in the United States?
Hot Mix Asphalt (HMA) is the dominant American paving material — used for 94% of paved roads and virtually all residential driveways and commercial parking lots. Standard US residential HMA is specified to PG 64-22 grade at 145 lbs/ft³ density, following AASHTO standards that apply uniformly across all 50 states.
How much does asphalt cost per ton in the United States?
American hot mix asphalt costs $85–$180 per ton in 2026 depending on region. The Southeast is cheapest ($85–$130/ton) due to proximity to Gulf Coast oil refineries. The Northeast and West Coast are most expensive ($110–$180/ton) due to higher labor costs and more stringent environmental regulations. The national average is approximately $115–$125/ton. See our full HMA price guide by state.
What is the average cost to pave a driveway in the United States?
American driveway paving costs $4–$7 per square foot installed, or $2,400–$4,200 for a standard 600 sqft driveway. Regional variation is significant: the Northeast averages $5–$9/sqft while the Southeast runs $3.50–$6/sqft. Use our free asphalt driveway calculator for a precise regional estimate for your specific dimensions.
How long does asphalt last in the United States?
American asphalt driveways last 15–20 years with regular maintenance — sealcoating every 2–3 years and crack filling as needed. US roads are typically resurfaced every 12–18 years under normal traffic conditions. Proper base preparation — 4–6 inches of compacted aggregate subbase — is the single most important factor determining US asphalt pavement longevity regardless of climate.
Is asphalt or concrete more popular in the United States?
Asphalt is significantly more popular for roads and driveways — 94% of all US paved road miles use asphalt. Concrete is more common for sidewalks, curbs, and some high-traffic Interstate segments. Asphalt dominates nationally due to its lower upfront cost ($4–$7/sqft vs $6–$12/sqft for concrete) and superior performance in freeze-thaw climates that affect most of the country.
What percentage of US roads are asphalt?
Approximately 94% of the 2.7 million miles of paved roads in the United States are surfaced with asphalt pavement, according to the Asphalt Pavement Alliance and NAPA. The remaining 6% are primarily Portland cement concrete (used on high-traffic Interstate segments and bridge decks) or composite pavements combining both materials.
