Three tools cover the driveway lifecycle
Material sizing, moving gravel with a tractor loader, and hauling it home on a trailer. Each tool answers a specific question — no guesswork, no round numbers.
Gravel Material Calculator
Enter length, width, and depth to see tons and cubic yards, including a compaction allowance.
Loader Lift Calculator
Check whether your compact tractor's front loader can move gravel and driveway material safely.
Trailer Payload Calculator
Size a dump-trailer haul so you don't overload the trailer moving gravel from the pit.
Plan your driveway repair, in order
Skip a step and you'll be ordering another load next spring. Work these five in sequence.
- 1
Diagnose the failure mode
Is it potholes, washboarding, ruts, migration off the crown, or wash-out at low points? Each has a different fix; blanket adding gravel wastes money if drainage is the real issue.
- 2
Measure the run and depth
Measure length and width in feet including turnouts. Choose a finished depth per layer that fits your job — topcoats are typically shallower than full rebuilds, and the right number depends on your existing base, soil, and traffic.
Size material - 3
Estimate tons and yards
Use the calculator to convert volume to tons at a crushed-stone density you can confirm with your supplier. Round up to full ton or yard increments and add a compaction allowance appropriate for the stone.
Run the numbers - 4
Plan drainage
Confirm ditches, culverts, and crown before ordering material. Fresh gravel on a driveway that doesn't shed water fails again the next hard rain.
- 5
Spread, grade, compact
Dump in piles, spread with a box blade, tractor bucket, or landscape rake, crown the middle, then compact with the equipment you have — a loaded truck or roller finishes it.
Topcoat, regrade, or rebuild?
Three common repair paths, and how to tell which one your driveway actually needs.
Topcoat only
When: Base is sound. Surface is thin, dusty, or lightly rutted.
Effort: 1 load of #57 or DGA, spread and grade.
Risk: Wastes material if base is the real problem.
Regrade + topcoat
When: Crown is gone or ruts are cutting into base but base is still there.
Effort: Cut high spots, redistribute, add fresh topcoat, re-crown.
Risk: Needs a box blade or landplane, or a hired grader pass.
Full rebuild
When: Base is muddy, showing clay, or has sections that heave/wash out.
Effort: Dig out failed sections, install fabric or larger stone base, then topcoat.
Risk: Highest cost — but skipping it means paying for topcoat every year.
Water is what actually destroys a driveway
Crown the middle
A slight rise in the center pushes water to the shoulders instead of down the wheel tracks.
Keep the ditches open
Grass, silt, and fallen limbs turn a good ditch into a sponge. Walk them each spring and fall.
Install culverts at low spots
Any point where water crosses the driveway needs a culvert sized for the runoff, not a filled-in dip.
Direct downspouts and gutters away
House and outbuilding downspouts dumping onto the driveway edge accelerate failure at exactly one point.
This hub is for planning, not engineering. County and state road departments set drainage standards for public and shared roads; verify local requirements for culverts and grading before doing anything at a property line.

Common gravel-driveway mistakes
Adding topcoat over failing base
New #57 stone rides across a soft, ungraded, or muddy base and disappears within a season. If ruts are showing base clay, rebuild the base before spending on topcoat.
Underestimating depth after compaction
Loose gravel loses depth after compaction — the exact amount varies by stone type, gradation, and moisture. Ordering exactly the loose-depth number can leave you short after the first storm and traffic; ask your supplier for a compaction allowance for the stone you're buying.
Skipping the crown
A driveway with no crown puddles water where the tires already wear it down. Build in enough crown to shed water sideways — the right amount depends on width, surface, and rainfall, and your local road department or contractor can suggest a target for your area.
Ignoring the low spots
Fresh material piles up in low spots and turns to soup after rain. Cut the low spot back to solid base, install a culvert or crossover, then rebuild the section.
Wrong stone for the job
Round river gravel looks nice but shifts under tires. Dense-graded aggregates (crush-and-run, DGA, or a minus-sized crushed stone) tend to lock together and compact harder — often preferred for structural layers. Confirm the right product with your local quarry.
One-time fix, no maintenance
Even a well-built rural driveway needs periodic grading and occasional topcoat refreshes. Budget for ongoing maintenance passes rather than counting on one giant rebuild.
Field notes
- Order in tons, not truckloads.
A tri-axle dump and a tandem dump carry very different amounts. Ordering by ton lets you compare quotes directly and reconcile against the scale ticket.
- Stage a small maintenance pile.
Keeping a few tons of matching stone on the property means you can drop material into fresh potholes before they widen — usually cheaper than a full grader pass.
- Compaction often matters more than raw depth.
Well-compacted material tends to outlast a thicker layer of loose stone through a wet season. Drive over new gravel in varied patterns to work it in before the first storm, and don't rely on a fixed compaction percentage — it varies by stone and conditions.

Driveway work usually touches other property projects — tractor lift capacity for moving material, trailer payload for hauling it, and gate opener sizing for the entrance at the top of the drive.

Local road departments and county engineers set requirements for shared roads, easements, and culverts — verify local rules before altering drainage, ditches, or driveway entrances at a right-of-way. Gravel densities and compaction rates vary by quarry and stone gradation.
