Texas Asphalt Calculator — Cost & Coverage (2025)

Texas hot mix averages around$175 per toninstalled in 2025 — about $15/ton below the national median. Markets vary widely: Houston and the Gulf Coast run near the state average, while Austin's booming demand and DFW's longer haul distances from limestone quarries push installed prices to $185–$200 per ton.

Out in West Texas and the Permian Basin, oilfield traffic and a long paving season keep prices flat, but specialized PG 70-22 or PG 76-22 binders for desert heat can lift the mix cost $5–$15 per ton. Ranch roads and long private driveways east of I-35 are usually quoted by the ton-mile once you factor trucking from the nearest plant.

Texas is the most climatically diverse of the three focus states: humid subtropical in the east, semi-arid in the west, and a band of highly expansive clay soils running through the central corridor — the Blackland Prairie from Dallas south through Austin and San Antonio. Texas expansive clay demands a thicker base and good drainage; a 6" base under 3" of asphalt is common for driveways in DFW and Austin. In west Texas, sun and oil volatility call for a stiffer PG 70-22 or PG 76-22 binder.

Expansive clay swells when wet and shrinks when dry, exerting enormous pressure on a rigid pavement. That makes the base — not the asphalt surface — the part that decides whether a Texas driveway lasts 5 years or 25. The standard Central Texas detail is 6 inches of compacted flexible base under 3 inches of hot mix, with a fabric separation layer over the worst clay. In West Texas, the bigger enemy is sustained 100°F+ heat and UV oxidation, which is why stiffPG 70-22or PG 76-22 binders are specified to resist rutting.

The most common Texas asphalt failures we see:

• Edge cracking from clay movement. Expansive clay under a thin base expands and contracts seasonally, opening parallel cracks along the edges of driveways and parking lots. The fix is almost always base-related: thicker base, better drainage, or a geotextile separation layer.
• Rutting in oilfield and ranch roads. Heavy truck traffic on a thin lift over weak subgrade deforms the wheel paths. West Texas Permian Basin operators routinely spec a stiff PG 76-22 binder and 6+ inches of asphalt for lease roads.
• Oxidation and raveling in West Texas. UV and sustained heat break down the binder, the surface goes gray and brittle, and aggregate pops loose. A sealcoat every 2–3 years is non-negotiable in El Paso, Midland-Odessa, and the Trans-Pecos.

Texas driveway thickness follows the national 2.5–3 inch compacted hot mix guideline, but the base underneath varies sharply by region. Over the Blackland Prairie expansive clays, plan on 6–8 inches of flexible base under 3 inches of asphalt; many contractors add a geotextile separation layer to bridge the worst soils. In Houston and East Texas, where rainfall exceeds 50 inches and sandy soils drain well, 4–6 inches of base is common.

DFW and Austin suburban subdivisions often use a 6-inch base + 3-inch hot mix detail for new driveways. Parking lots carrying light traffic get 3–4 inches of asphalt over 6–8 inches of base; roads and oilfield lease roads spec 4–6 inches of asphalt over 8+ inches of base. Use the Project Type selector above to snap thickness to the right starting point.

Once you have a tonnage number, get itemized written quotes from at least three Texas-licensed paving contractors. A reputable Texas contractor will list base prep (including any necessary soil stabilization or geotextile), demolition and haul-off, the per-ton rate, the mix design and PG binder, permit fees, and warranty terms.

Confirm they carry workers' comp and general liability — Texas is the only state where workers' comp is optional, so ask explicitly. For Central Texas jobs especially, the contractor's experience with expansive clay is the single biggest predictor of whether the pavement will last.
