How Much Does Asphalt Cost in Colorado?
Asphalt averages $128.70 per ton in Colorado as of 2026 research, with metro-level pricing ranging from $126.13 (lowest-cost metro) to $135.14 (highest-cost metro). That's a 10% premium over the national midpoint of $117.00 per ton (source; confidence: high). The state midpoint is computed by applying Colorado's 1.10× regional adjustment to the national-average dataset documented on our pricing methodology page.

What Drives Asphalt Pricing in Colorado?
Colorado runs roughly 10% above the national midpoint. Denver anchors the state in the Mountain West's +5-15% cost band, and expansive-soil foundations, home-rule permitting with construction use-tax deposits, and freight into a landlocked market push pricing up; the low 2.9% state sales tax pulls slightly the other way. Mountain resort counties (Aspen, Vail, Summit) run far higher on freight and labor scarcity but sit outside the major Front Range metros priced here.
Climate and supply factors: Expansive bentonite and claystone soils along the Front Range are the dominant cost driver — swelling soils crack conventional footings and often force drilled piers into bedrock and structural (suspended) floors over void space, the most expensive foundation approach in residential construction. High-altitude UV and freeze-thaw cycling push air-entrained, durability-rated mixes and accelerate sealant and membrane wear, and mountain-county snow loads and wildland-urban-interface (WUI) requirements raise structural material at elevation.

When to Buy Asphalt in Colorado
Construction season in Colorado: April-October, with a September-early October sweet spot; the Front Range builds nearly year-round because high-altitude sun clears transient snow quickly, while ACI 306 cold-weather protection kicks in from late October and mountain counties run a much shorter season.
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 Colorado, 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 Colorado
Frost line: 36 in (Denver/Front Range standard); deeper in higher-elevation mountain counties by local amendment. Frost line drives footing and base depth on hardscape projects — though it has less direct impact on per-ton asphalt pricing.
State / local code: Colorado has no statewide structural building code — adoption is local under home rule, so Denver enforces its own Denver Building & Fire Code and other jurisdictions (Colorado Springs' Pikes Peak Regional Building Department, unincorporated counties) adopt and amend the I-Codes independently. What is statewide is energy code: under 2023 legislation (HB23-1255) any jurisdiction updating its codes must adopt the 2021 or 2024 IECC plus Colorado's electric- and solar-ready provisions, tightening to the state's Model Low Energy and Carbon Code from mid-2026, administered by the Colorado Energy Office.
Where to Find Asphalt Suppliers in Colorado
Authoritative directories for sourcing ready-mix producers, aggregate quarries, and bagged-product retailers across Colorado:
- Colorado Ready Mixed Concrete Association (CRMCA) member directory
- 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 Colorado's 1.10× 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 1.10 for a Colorado-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 Colorado?
Asphalt averages $128.70 per ton in Colorado, with a metro range of $126.13 to $135.14 as of 2026. Colorado pricing runs about 10% above the national midpoint.
What is the cheapest Colorado metro for asphalt?
Fort Collins typically prices the lowest of the major Colorado metros, around $126.13 per ton. Denver typically prices the highest, around $135.14. Differences come from delivery distance to producer plants and metro-area labor rates.
When is the best time of year to buy asphalt in Colorado?
April-October, with a September-early October sweet spot; the Front Range builds nearly year-round because high-altitude sun clears transient snow quickly, while ACI 306 cold-weather protection kicks in from late October and mountain counties run a much shorter season. 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 Colorado?
Colorado has no statewide structural building code — adoption is local under home rule, so Denver enforces its own Denver Building & Fire Code and other jurisdictions (Colorado Springs' Pikes Peak Regional Building Department, unincorporated counties) adopt and amend the I-Codes independently. What is statewide is energy code: under 2023 legislation (HB23-1255) any jurisdiction updating its codes must adopt the 2021 or 2024 IECC plus Colorado's electric- and solar-ready provisions, tightening to the state's Model Low Energy and Carbon Code from mid-2026, administered by the Colorado Energy Office.
Where can I find asphalt suppliers in Colorado?
Start with the Colorado Ready Mixed Concrete Association (CRMCA) member directory, the NRMCA national producer directory filtered to Colorado, 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 Colorado than the national average?
Colorado runs roughly 10% above the national midpoint. Denver anchors the state in the Mountain West's +5-15% cost band, and expansive-soil foundations, home-rule permitting with construction use-tax deposits, and freight into a landlocked market push pricing up; the low 2.9% state sales tax pulls slightly the other way. Mountain resort counties (Aspen, Vail, Summit) run far higher on freight and labor scarcity but sit outside the major Front Range metros priced here.
