Asphalt or Concrete Driveway: Which Fits a Sacramento Valley Home?

Concrete costs more up front and lasts longer with less upkeep. Asphalt costs less and is ready for cars sooner. It patches more easily, but it needs sealcoating every few years. National cost guides put asphalt at $5 to $15 a square foot installed and concrete at $6 to $20.

Those are market numbers from published guides, not our price list. In the valley, summer heat favors concrete, and long rural drives often favor asphalt. Trinity Paving and Concrete builds both concrete driveways and asphalt driveways. The right pick depends on your lot and how you use the drive.

How do asphalt and concrete driveways compare?

Which costs more up front?

Concrete, in every national cost guide we checked. One lists asphalt at $5 to $12 a square foot and concrete at $6 to $15. Another lists $7 to $15 for asphalt and $8 to $20 for concrete.

Take a 20 by 20 foot two-car pad, or 400 square feet. The first guide’s ranges put asphalt near $2,000 to $4,800 and concrete near $2,400 to $6,000.

Length widens the gap. A rural drive 12 feet wide and 300 feet long is 3,600 square feet. At the same ranges, that is about $18,000 to $43,200 in asphalt and $21,600 to $54,000 in concrete.

This is rough math, not a quote. Our post on what an asphalt driveway costs in Northern California covers the asphalt side.

How does a 100 degree summer treat each one?

Valley summers run hot and dry. Federal climate normals for 1991 to 2020 count about 17 days a year at 100 F or hotter near Davis. The Vacaville station averages about 28, and Sacramento Executive Airport about 14. Dixon sits between the Davis and Vacaville stations.

Pavement runs much hotter than the air. A federal report on urban heat says asphalt and concrete can reach 120 to 150 F in summer. New asphalt reflects little sunlight, so it soaks up more heat. The report counts new concrete as a cool pavement, though it darkens with traffic and dirt.

Heat softens the binder that holds asphalt together. A state asphalt pavement association says new asphalt can show tire scuffs and dents in hot weather. Turning the steering wheel while the car sits still is one cause. Kickstands and trailer jacks can dent it too, so the group suggests plywood under jacks.

The same group says most marks fade under traffic and do not shorten the pavement’s life. Cost guides describe concrete as minimally affected by hot weather.

What does valley clay do to a driveway?

Rain here comes in one season. At all three stations, more than 80 percent of the year’s rain falls November through March. Clay soaks up that water in winter and dries out over the long summer.

Federal soil survey data maps most of Dixon as silty clay loam, with heavier clay east and south of town. The survey rates the main soils there “very limited” for local roads and streets. It cites low strength for all of them and shrink-swell for the heavier clays. One of those clays has cracks that “open and close at least once each year,” the survey says.

Low strength means the native soil carries weight poorly. Shrink-swell means clay swells when wet and shrinks as it dries. The survey’s road rating calls asphalt a flexible surface and concrete a rigid one.

Concrete holds its shape until the ground moves, and then it cracks. Control joints give those cracks a straight, planned place to form. Asphalt bends a little first, and cost guides say its cracks are easier to repair.

A state asphalt pavement association links alligator cracking to a weak subgrade. So under either surface, we prep and compact the subgrade first. Grading that sheds water off the drive matters just as much.

Which one needs more upkeep?

Asphalt needs more. Cost guides suggest sealcoating every 2 to 3 years. Cracks should be filled before the winter rain reaches the base. A state asphalt pavement association warns that fuel and oil spills dilute the liquid asphalt.

Concrete needs less. Cost guides call a sealer recommended rather than required, about every 2 to 3 years.

Which is easier to repair?

Asphalt. Potholes get cut back to solid pavement and patched. Alligator-cracked areas come out, and the base under them gets rebuilt.

Both jobs fall under asphalt repair. When the top wears out over a sound base, an overlay adds a new layer of hot mix.

Concrete is harder to fix well. One cost guide warns that concrete repairs stand out against the weathered slab around them. A broken or sunken slab usually gets cut out at the joints and poured again.

Which looks better and helps resale?

Asphalt starts black and fades toward gray as the binder ages. It hides dirt and stains well. Concrete starts light gray and darkens with traffic, and oil drips show on it more. It can take color or a stamped pattern at a higher price.

One national cost guide claims a well-designed concrete driveway may add 5 to 10 percent to property value. Treat that as a guide’s estimate, not an appraisal. A buyer notices condition first, such as wide cracks or heaved slabs.

When is each one the right call?

Concrete fits when:

• you want the longest life and the least upkeep
• you can keep cars off it for about a week while it cures
• a trailer or RV sits on the drive through the hot months
• the drive is short, so the cost gap stays small

Asphalt fits when:

• the drive is long, like a rural run out to the road
• you need the drive back in use within a few days
• an old gravel drive has a sound base that can be regraded and paved
• you would rather patch and reseal than replace slabs

Some owners use both. A concrete pad by the house can meet an asphalt run out to the road.
