How Much Does Asphalt Cost in Wyoming?
Asphalt averages $119.34 per ton in Wyoming as of 2026 research, with metro-level pricing ranging from $116.95 (lowest-cost metro) to $121.73 (highest-cost metro). That's a 2% premium over the national midpoint of $117.00 per ton (source; confidence: high). The state midpoint is computed by applying Wyoming's 1.02× regional adjustment to the national-average dataset documented on our pricing methodology page.

What Drives Asphalt Pricing in Wyoming?
Wyoming construction runs about 2% above the national average. It is a rural Mountain West state with low labor and land costs in most areas, but long haul distances, a thin supplier network, and an energy-driven boom-bust economy can push delivered material prices up, and the resort market around Jackson / Teton County is far more expensive than the rest of the state.
Climate and supply factors: Wyoming is the windiest state in the continental U.S., and wind, not snow or seismic activity, often governs structural design, especially in the southeast around Cheyenne, where sustained winds routinely top 30 mph and spring gusts can reach 60-80 mph. Expansive soils are the other dominant factor: Wyoming holds a very large share of the world's bentonite, a high-swelling montmorillonite clay, and swelling clays and shale are widespread, so foundation heave and cracking are common failure modes. Add deep frost at elevation and a short high-elevation building season, and site-specific geotechnical and wind-load design matter more here than the state's near-average cost level suggests.
Asphalt Prices by Wyoming's Major Metros
Per-metro estimates apply each metro's population-weighted price tier to the Wyoming state midpoint. Population figures are 2024 ACS estimates from the U.S. Census Bureau.
| Metro | Population | Per Ton | vs. State Avg |

| Cheyenne | 65K | $120.53 | +1% |
| Casper | 59K | $121.73 | +2% |
| Gillette | 33K | $119.34 | — |
| Laramie | 32K | $116.95 | -2% |
| Rock Springs | 23K | $118.15 | -1% |
When to Buy Asphalt in Wyoming
Construction season in Wyoming: The heavy pour-and-pave season runs roughly May through October, and it is shorter at elevation. High-elevation basins and mountain towns such as Laramie and Jackson lose more of the shoulder season to cold, and relentless spring wind can shut down crane and framing work even on days that are otherwise warm enough to build.
Hot-mix asphalt plants typically run April-November and shut down in winter; spring re-opening pricing tends to be the year's lowest while late-summer is the year's highest. For non-emergency work in Wyoming, ordering during the off-peak window typically saves 5-15% vs. spring/summer peak pricing. Material yards run promotional pricing twice a year — early-spring (Mar-Apr) on bagged products and late-fall (Oct-Nov) on bulk aggregates as plants clear inventory before shutdown.
Climate & Code Considerations for Asphalt in Wyoming
Frost line: 42-48 in across the high-plains southeast (Cheyenne / Laramie County commonly designs to ~42 in); deeper (48 in or more) at higher elevations and in the colder mountain basins. Wyoming sets no single statewide frost depth, so the required footing depth is defined by the local jurisdiction, verify with the county or city building department.. Frost line drives footing and base depth on hardscape projects — though it has less direct impact on per-ton asphalt pricing.
State / local code: Wyoming has NO mandatory statewide building code. Adoption and enforcement are entirely local: incorporated cities and some counties adopt editions of the International Building Code (IBC) and International Residential Code (IRC), often with local amendments, while many rural and unincorporated areas have no building code and no permitting at all. The state does maintain a few statewide trade programs (for example a state electrical code based on the NEC), but there is no comprehensive state building code, always confirm which codes, if any, your specific jurisdiction enforces.
Where to Find Asphalt Suppliers in Wyoming
Authoritative directories for sourcing ready-mix producers, aggregate quarries, and bagged-product retailers across Wyoming:
- Associated General Contractors (AGC) of Wyoming
- NRMCA ready-mix producer directory (filter by state)
- Quikrete dealer locator
Get quotes from at least three local suppliers — pricing on the same spec varies 10-20% across producers in the same metro. Volume orders (10+ cu yd ready-mix, 20+ tons aggregate, full pallets bagged) typically earn another 5-10% off published quotes.
Calculate Asphalt for Your Project
Use our Asphalt Calculator to estimate quantity, then apply Wyoming's 1.02× adjustment to the national-average cost displayed on the calculator. The calculator's built-in cost overlay uses national pricing — multiply the displayed total by 1.02 for a Wyoming-specific estimate, or use the per-metro figures in the table above for tighter budgeting.
Frequently Asked Questions
How much does asphalt cost per ton in Wyoming?
Asphalt averages $119.34 per ton in Wyoming, with a metro range of $116.95 to $121.73 as of 2026. Wyoming pricing runs about 2% above the national midpoint.
What is the cheapest Wyoming metro for asphalt?
Laramie typically prices the lowest of the major Wyoming metros, around $116.95 per ton. Casper typically prices the highest, around $121.73. Differences come from delivery distance to producer plants and metro-area labor rates.
When is the best time of year to buy asphalt in Wyoming?
The heavy pour-and-pave season runs roughly May through October, and it is shorter at elevation. High-elevation basins and mountain towns such as Laramie and Jackson lose more of the shoulder season to cold, and relentless spring wind can shut down crane and framing work even on days that are otherwise warm enough to build. Hot-mix asphalt plants typically run April-November and shut down in winter; spring re-opening pricing tends to be the year's lowest while late-summer is the year's highest. For non-emergency work, ordering off-peak (late fall in cold-winter states, mid-winter in southern states) typically saves 5-15% vs. spring/summer peak pricing.
What code requirements affect asphalt costs in Wyoming?
Wyoming has NO mandatory statewide building code. Adoption and enforcement are entirely local: incorporated cities and some counties adopt editions of the International Building Code (IBC) and International Residential Code (IRC), often with local amendments, while many rural and unincorporated areas have no building code and no permitting at all. The state does maintain a few statewide trade programs (for example a state electrical code based on the NEC), but there is no comprehensive state building code, always confirm which codes, if any, your specific jurisdiction enforces.
Where can I find asphalt suppliers in Wyoming?
Start with the Associated General Contractors (AGC) of Wyoming, the NRMCA national producer directory filtered to Wyoming, or the Quikrete dealer locator for bagged products. Get quotes from at least three local suppliers — pricing varies 10-20% across producers in the same metro.
Why is asphalt more expensive in Wyoming than the national average?
Wyoming construction runs about 2% above the national average. It is a rural Mountain West state with low labor and land costs in most areas, but long haul distances, a thin supplier network, and an energy-driven boom-bust economy can push delivered material prices up, and the resort market around Jackson / Teton County is far more expensive than the rest of the state.
