Short answer: asphalt wins the day you pay for it — roughly $7–$13 per square foot against about $35 for permeable pavers. Permeable wins most days after that: it's bought once instead of resurfaced on a 15–20 year cycle, it repairs in sections instead of in acres, and it drains rain straight down instead of at your foundation or the street — which is why it earns Somerville Green Score credit and asphalt counts against you. If your driveway has a water problem, this isn't really a comparison; it's a drainage fix that happens to look great.
Full disclosure up top: we build permeable paver driveways and we don't pave asphalt, so read us the way you'd read anyone with a side. We'll make the honest case anyway — including the situations where blacktop is genuinely the sensible call.
Head to head
| Permeable pavers | Asphalt | |
|---|---|---|
| Installed cost | About $35/sq ft (our real rate) | $7–$13/sq ft market range* |
| Life cycle | Bought once; sections lift & reset if ever needed | Sealcoat every few years; resurface/replace on a 15–20 yr cycle* |
| Rainwater | Drains straight through into a stone reservoir below | Sheds 100% toward street, lawn, or your basement |
| Somerville Green Score | Earns credit | Counts against you (impervious) |
| Summer / winter | Stays solid; melt drains, less refreeze ice | Softens in heat; cracks with freeze-thaw; ponds & ices |
| Repairs | Localized — reset the section | Patches show; big fixes mean repaving |
| Looks | Designed surface; patterns, borders, curb appeal | Blacktop |

"Asphalt gets bought twice" — the lifecycle math
The sticker gap is real, so let's be fair about what each dollar buys. A 400 sq ft city driveway runs about $14,000 in permeable pavers with us, versus maybe $3,000–$5,000 in asphalt at market rates. But blacktop is a subscription: sealcoating every few years, crack-filling, and somewhere around year 15–20 in this climate, the resurfacing or replacement bill — plus another ~$5,300 per 1,800 sq ft in remove-and-haul when the old surface finally comes out. The paver driveway is bought once, on a base built for vehicles, and 20 years in, its "major maintenance" is topping up joint stone. Neither math makes the other dishonest — they're just different purchases: one cheap and recurring, one premium and permanent.
The water is the real story
Here's the part that turns this from a looks-and-money question into a house question. An asphalt driveway is an impervious ramp: every inch of rain that hits it goes somewhere — the street, the lawn, or downhill toward your foundation. In the inner-ring towns, "my basement gets water every big storm" and "my driveway slopes at the house" are very often the same sentence. A permeable driveway breaks that chain: water passes through the stone-filled joints into an open-graded crushed-stone reservoir underneath and soaks away where it lands. That's not a side benefit — for a lot of our projects it's the reason the phone rang. If that's your situation, start at why your yard floods, and see how the system works in permeable vs. regular pavers.
The Somerville & Cambridge wrinkle
In Somerville, surfaces are scored: permeable paving earns Green Score credit and asphalt counts against you as impervious cover — which can decide what you're allowed to build. Cambridge and Boston are moving the same direction on stormwater. If your project touches the Green Score, the comparison mostly makes itself; we handle the scorecard and the install end to end. Curb cuts and street permits work the same for both surfaces — details in the cost guide.
Winter, honestly
Both surfaces live through the same New England winter; they just fail differently. Asphalt softens in July, cracks with freeze-thaw, and its low spots pond and refreeze into skating rinks. A permeable driveway plows and shovels like any paver surface, and because meltwater drains through instead of sitting, it tends to ice less — go easy on straight rock salt, same as any concrete paver. Freeze-thaw is the exact stress paver systems are designed for: thousands of units flexing with the ground instead of one sheet fighting it.
When asphalt honestly wins
Our lane is stone, but fair is fair. Choose asphalt when budget rules and there's no water problem to solve: a long suburban driveway where $35/sq ft times 1,500 feet isn't in the cards, a rental or flip where the 15–20 year cycle is someone else's problem, or a surface you simply want blacked over cheaply this year. That's a rational purchase — just make it knowing it's a lease, not a buy. And if the driveway is sending water at your house, patching that with more asphalt is paying to keep the problem.

Permeable vs. asphalt FAQs
Is a permeable driveway more expensive than asphalt?
Up front, yes: about $35/sq ft installed versus roughly $7–$13 market range. Over decades the gap narrows — asphalt gets sealcoated and then resurfaced or replaced on a 15–20 year cycle; permeable is bought once and repaired in sections.
Which lasts longer?
Permeable pavers. Asphalt softens, cracks, and cycles every 15–20 years here; a paver system on a vehicle-rated open-graded base flexes with frost, and settled sections get reset, not repaved.
Do permeable driveways help with basement water?
Often dramatically — asphalt sheds every drop toward the street or your foundation, while permeable drains it straight down into the stone reservoir below. For many of our projects, that's the whole reason for the job.
Does permeable count toward the Somerville Green Score?
Yes — it earns credit, while asphalt counts against you as impervious surface. We handle the scorecard and install end to end.
How does permeable handle snow and plowing?
Plows and shovels like any paver surface, and ices less because melt drains through instead of ponding and refreezing. Go easy on straight rock salt.
When is asphalt the right choice?
When budget rules and there's no water problem: big driveways on tight budgets, or surfaces you're happy to maintain on asphalt's cycle. Lowest cost going in — just know it's a 15–20 year lease, not a purchase.
