Honest comparison
Gravel vs Asphalt Driveway
Gravel is the low-cost, self-repairing, DIY-able surface that asks for a rake and a top-up forever. Asphalt is the clean, plough-able, higher-cost surface on a clock that starts at sealing time.
Gravel is less a surface than a maintained state. It goes down cheap, drains through itself, laughs at frost, and any pothole is fixed by the owner with a shovel in ten minutes. In exchange it migrates — into the lawn, down the slope, out of the wheel tracks — grows weeds wherever organic dust settles into it, and gets plowed only by someone with a careful blade height.
Asphalt is a committed structure: a compacted base under machine-laid hot mix, edges that need support, and a schedule — sealing on a cycle, crack-filling before water gets under, and eventually an overlay. In exchange you get a clean surface for bikes and shoes, effortless snow clearing, and no migration. Its enemy is water under the mat: a poor base or an unfilled crack in freeze-thaw country turns into alligatored patches faster than any brochure admits.
Length changes the answer. A short suburban drive amortises asphalt's fixed costs badly and gravel's containment problem is small. A long rural drive flips both: asphalt's cost per metre marches on relentlessly, while gravel's occasional grading is what tractors are for.
The factors that actually differ
| Gravel | Asphalt | |
|---|---|---|
| Repair | Owner-fixable with a shovel, forever. | Crack-fill and patch on a schedule; big failures mean a contractor. |
| Drainage | Drains through itself; puddles mean the base needs grading, not the surface. | Sheds water — which must be given somewhere to go, or it finds the edges. |
| Snow and ice | Ploughing skims gravel into the yard; know your blade height. | The plough-and-shovel surface, no contest. |
| Freeze-thaw | Indifferent — it already moves. | Water in cracks is the mortal enemy; discipline with the crack filler decides its life. |
| Slopes | Washes downhill; steep runs need containment or a different surface. | Holds any drivable grade. |
| Kerb feel | Rural, informal, crunchy. | Suburban, finished, quiet. |
Choose gravel when…
- Long runs where paving cost per metre is decisive.
- DIY maintenance culture — you would rather rake quarterly than schedule contractors.
- Freeze-thaw ground that eats rigid surfaces.
Choose asphalt when…
- Snow country with a plough or blower doing the mornings.
- Slopes gravel would abandon.
- The clean threshold: bikes, prams, shoes and the house's first impression.

Frequently asked questions
- Does gravel really need topping up?
- Yes, on a cycle measured in years — it migrates, compacts into the base and disappears into mud in soft spots. The honest budget for gravel is not zero maintenance but CHEAP maintenance: a delivery every few years and grading in between. Budget the top-up, not the fantasy.
- Can I asphalt over my gravel drive?
- Sometimes — the existing gravel can become part of the base if it is deep, clean and compacted, which is exactly what a paving contractor will assess. Thin, muddy or organic-contaminated gravel gets excavated anyway. Either way asphalt's life is decided by that base, so this is the wrong corner to cut.
- What actually kills asphalt drives?
- Water under the mat, almost every time. A crack goes unfilled, water gets beneath, freeze-thaw pumps it, the base softens and the surface alligators over the failure. Sealing is cosmetic-plus-protective; CRACK FILLING is the life-extender. Ten minutes with filler in autumn beats a patch crew in spring.
