How Much Does Asphalt Cost in South Carolina?
Asphalt averages $107.64 per ton in South Carolina as of 2026 research, with metro-level pricing ranging from $102.26 (lowest-cost metro) to $118.40 (highest-cost metro). That's 8% below the national midpoint of $117.00 per ton (source; confidence: high). The state midpoint is computed by applying South Carolina's 0.92× regional adjustment to the national-average dataset documented on our pricing methodology page.

What Drives Asphalt Pricing in South Carolina?
South Carolina runs roughly 8% below the national midpoint — a below-average-cost Southeast state on labor and materials, pulled back up on the coast by hurricane wind requirements and the Lowcountry's distinctive seismic detailing. Charleston and the coastal metros carry a premium from wind and seismic demands, coastal logistics, and higher local cost of living, while the upstate (Greenville-Spartanburg) and interior markets are cheaper.
Climate and supply factors: The Charleston (Middleton Place-Summerville) seismic zone gives the Lowcountry the highest earthquake risk in the Southeast — the 1886 Charleston quake drives real seismic detailing on coastal foundations, and roughly 10-15 small earthquakes are recorded in the state each year. Atlantic hurricane wind zones push coastal design speeds to 130 mph and up, and soft, saturated Coastal Plain soils (liquefaction-prone in a seismic event) contrast with firmer upstate Piedmont ground.
Asphalt Prices by South Carolina's Major Metros
Per-metro estimates apply each metro's population-weighted price tier to the South Carolina state midpoint. Population figures are 2024 ACS estimates from the U.S. Census Bureau.
| Metro | Population | Per Ton | vs. State Avg |
|---|---|---|---|
| Charleston | 154K | $118.40 | +10% |
| Columbia | 140K | $107.64 | — |
| North Charleston | 120K | $113.02 | +5% |
| Mount Pleasant | 94K | $118.40 | +10% |
| Rock Hill | 75K | $102.26 | -5% |
When to Buy Asphalt in South Carolina
Construction season in South Carolina: March-November, with a long mild season and roughly 10-15 workable winter weeks; summer heat and humidity (not cold) are the main constraint, favoring pours at 50-85°F.
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 South Carolina, 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 South Carolina
Frost line: 0-6 in (coastal ~0 in, upstate Piedmont a few inches); the SC Residential Code applies a flat 12 in minimum footing depth rather than a mapped frost line. Frost line drives footing and base depth on hardscape projects — though it has less direct impact on per-ton asphalt pricing.
State / local code: South Carolina adopts statewide codes through the SC Building Codes Council — the 2021 SC Building Code (IBC) and 2021 SC Residential Code (IRC) with state modifications, mandatory statewide since January 1, 2023. Local jurisdictions enforce and may amend only within the state framework, and coastal counties layer high-wind provisions on top.
Where to Find Asphalt Suppliers in South Carolina
Authoritative directories for sourcing ready-mix producers, aggregate quarries, and bagged-product retailers across South Carolina:
- Carolinas 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 South Carolina's 0.92× 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 0.92 for a South Carolina-specific estimate, or use the per-metro figures in the table above for tighter budgeting.
Frequently Asked Questions

When is the best time of year to buy asphalt in South Carolina?
March-November, with a long mild season and roughly 10-15 workable winter weeks; summer heat and humidity (not cold) are the main constraint, favoring pours at 50-85°F. 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 South Carolina?
South Carolina adopts statewide codes through the SC Building Codes Council — the 2021 SC Building Code (IBC) and 2021 SC Residential Code (IRC) with state modifications, mandatory statewide since January 1, 2023. Local jurisdictions enforce and may amend only within the state framework, and coastal counties layer high-wind provisions on top.
Where can I find asphalt suppliers in South Carolina?
Start with the Carolinas Ready Mixed Concrete Association (CRMCA) member directory, the NRMCA national producer directory filtered to South Carolina, 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 South Carolina than the national average?
South Carolina runs roughly 8% below the national midpoint — a below-average-cost Southeast state on labor and materials, pulled back up on the coast by hurricane wind requirements and the Lowcountry's distinctive seismic detailing. Charleston and the coastal metros carry a premium from wind and seismic demands, coastal logistics, and higher local cost of living, while the upstate (Greenville-Spartanburg) and interior markets are cheaper.
