How Much Does a Gravel Driveway Cost in Texas?
National cost guides put a gravel driveway at about $1 to $3 per square foot on the low end. The high end runs $4 to $10 per square foot installed. On a 100 by 10 foot drive, the low range comes to about $1,000 to $3,000. The high range comes to about $4,000 to $10,000.
Those are market numbers, not our price list. Most of the gap between the two ranges is ground work: grading, base layers, rolling and the haul. That ground work is what holds up a gravel or road base driveway on Brazos Valley clay.
Why do the cost guides disagree so much?
Both published ranges count rock and labor, so the gap is mostly the work under the rock. One national cost guide lists grading alone at $1 to $3 per square foot. That matches the other guide’s whole range for a finished gravel drive.
The guide that prices grading also puts labor at about 50 percent of the total project cost. The other guide puts a typical job at $300 to $4,500, with an average around $1,500.
So read each range against the job in front of you. A drive that only needs a fresh layer of rock will read closer to the low numbers. A new drive cut in from bare pasture, graded, based in layers and rolled, sits closer to the high ones. That full build is the core of our gravel driveway and road base work.
What does gravel cost per ton?
National cost guides say gravel typically runs $25 to $100 per ton. One guide breaks it out by rock type, with delivery included:
| Rock type | Price per ton, delivered |
|---|---|
| Crusher run | $25 to $50 |
| Crushed stone | $30 to $60 |
| Crushed shell | $40 to $80 |
| Pea gravel | $50 to $100 |
| River rock | $60 to $150 |
One ton covers about 60 to 80 square feet at 4 inches deep. So a 1,000 square foot drive takes about 13 to 17 tons at that depth. At the crusher run prices above, that is roughly $325 to $850 in rock before any labor. The guides recommend more than 4 inches for a new drive, so plan on more tons.
The kind of rock matters for more than price. The Federal Highway Administration (FHWA) gravel roads guide says broken stones embed much better than rounded, natural-shaped stone. It adds that fractured stone resists movement under loads better. Pea gravel and river rock are rounded stone, and they cost more per ton in the table above.
What moves the price of a gravel driveway in Texas?
A Texas gravel driveway price turns on the base material, the depth, the clay under it and the grading. The culvert at the road, the compaction and the haul distance count too.
The base material. Road base is what TxDOT calls flexible base. Its spec lists crushed stone as Type A, crushed concrete under Type D and caliche under Type E. The price per ton differs by material and by how far it rides to your drive.
The depth. National cost guides call for at least 5 to 6 inches, placed in layers. Drives that carry trucks or RVs want at least 8 to 12 inches. Every added inch means more tons on the truck.
The clay under it. The Zulch soil series has its type location just outside Bryan. It is a claypan soil of east-central Texas. When dry it cracks 1/2 inch to 1-1/2 inches wide, and the cracks reach 40 inches or more. Water moves through it very slowly.
FHWA’s guide says fabric laid on a weak subgrade keeps wet silt and clay from pumping into new rock. Without it, the guide says, pumping will contaminate and weaken the new material very quickly. Digging out soft spots or laying fabric adds cost up front, and it protects the rock above.
Grading and crown. National cost guides put grading at $1 to $3 per square foot. FHWA’s guide recommends a crown that rises about 1/2 inch per foot, roughly 4 percent. That slope sends rain off to the sides instead of down the wheel ruts.
The culvert at the road. Where your drive crosses the roadside ditch, the pipe is its own line item. National cost guides put culverts or drains at $500 to $2,000, depending on the property.
Madison County sets its minimum culvert at 24 feet long and 15 inches across. The precinct commissioner makes the final determination. Our page on driveway culvert installation covers how the pipe gets bedded and backfilled.
Compaction. TxDOT compacts flexible base to at least 100 percent of its maximum dry density. The moisture has to sit within 2 percent of optimum. Getting there takes water, a roller and passes over each layer. That time on the roller is part of the price.
The haul and the size of the job. Rock is sold by the ton and hauled by the truckload. The price depends on the size of the job, the material cost and the mileage. Small jobs cannot be priced by the square foot.
Do you need a permit for a gravel driveway in Madison County?
Not to add rock. Madison County’s driveway access permit checklist says adding a layer of gravel to an existing gravel driveway needs no permit. A new driveway needs one, and so does installing a culvert or changing a dirt driveway to asphalt. The county lists the application fee as none at this time.
A drive onto a state highway, a US route or an FM road sits on TxDOT right of way. TxDOT allows no driveway construction there until a fully executed permit is in hand. Around North Zulch that means SH 21, US 190 and FM 39.
Other counties and cities write their own rules. Ask the county road and bridge office or the precinct commissioner before the work starts.
How often does a gravel driveway need new rock?
There is no fixed schedule, because traffic and rain carry rock away at different rates. FHWA’s guide puts the loss on a road at up to one ton of rock per mile each year. That is for each vehicle that passes daily, and the loss varies with rainfall and gravel quality.
A driveway sees far fewer trips than a county road, but its rock still thins and washes out. Topping off an existing drive skips most of the ground work, and in Madison County it needs no permit. If the crown is gone, regrade first. FHWA’s guide says good surface gravel should be replaced only after the road’s shape and drainage are rebuilt.
When does it make sense to pave a gravel driveway?
When you are tired of adding rock and regrading, a paved surface over the same base is the next step. The base you build now is the base the pavement sits on later.
Chip seal is liquid asphalt sprayed on the base with rock rolled into it, in two or three courses. TxDOT says a surface treatment on a crushed stone base gives the least expensive permanent type of bituminous surface. Chip seal is that kind of surface treatment.
An asphalt driveway is hot mix laid with a paver over that same base and rolled while it is hot. Both surfaces need a sound, compacted base under them.
Asphalt millings are a third choice: recycled pavement spread, graded and rolled like road base. Our post on what a millings driveway costs covers the numbers and the tradeoffs.
