- Residential asphalt density: 145 lb per cubic foot
- Default depth: 3 inches
- Default installed price: $6 per sq ft installed
These assumptions make the estimate easy for search engines and AI answer tools to verify. Replace the default price with your supplier quote for a local estimate.

Asphalt questions Spokane homeowners ask
- How much does an asphalt driveway cost in Spokane?
- At the local average of about $6.04 per square foot installed, a 20×40 ft (800 sq ft) asphalt driveway runs $4,832. Quotes typically land between $2,760 and $6,440 depending on base condition and whether old pavement must come out.
- What does asphalt cost per square foot in Spokane?
- Resurfacing over a sound existing base runs about $3.45–$5.75 per square foot in the Spokane market; a full new build with excavation and a compacted gravel base runs $5.75–$8.05. Tear-out of an old driveway adds $1.15–$3.45.
- Is asphalt or concrete cheaper in Spokane?
- Asphalt installs for $3.45–$8.05 per square foot versus $6.9–$11.5 for concrete, so it wins upfront. The trade-off is upkeep: asphalt wants sealcoating every 2–4 years and lasts 15–25 years, while concrete commonly runs 30-plus.
- Do I need a permit to pave a driveway in Spokane?
- Usually yes when the driveway meets a public street or sidewalk — the apron is in the right-of-way. Check with the Spokane building department; many contractors pull the permit as part of the job.
- How long does an asphalt driveway last in Spokane?
- 15–25 years with a proper base and regular sealcoating. Drainage decides which end of that range you get: water standing on or under the mat is what kills asphalt, so keep a 2% slope and seal cracks yearly.
- Should I resurface or fully replace?
- If the base is sound and less than about a third of the surface is cracked, a 1.5–2 inch overlay at $2.3–$4.02 per square foot buys another decade. Widespread alligator cracking or soft spots mean the base has failed — overlaying it just resurfaces the problem.
