How Long Does an Asphalt Driveway Last? (And How to Make It Last Longer)

An asphalt driveway lasts 15 to 25 years when it's installed properly and maintained. The difference between the low and high end of that range comes down almost entirely to maintenance — mostly sealing on schedule and fixing small problems before they spread. In Ottawa's freeze-thaw climate, that maintenance matters even more.

How long does an asphalt driveway last?

With routine maintenance, a residential asphalt driveway lasts 15–25 years. Maintenance is the deciding factor: sealing every two to three years can preserve asphalt for about 20 years, whereas an unsealed driveway may last only around 12. In freeze-thaw regions like Ottawa, water intrusion is the main enemy — so sealing and prompt crack repair directly extend lifespan.

How often should you seal an asphalt driveway?

The standard recommendation is to seal every 2 to 3 years. In harsh-winter climates like Ottawa's, every 2 years is often the safer interval, because even small cracks let water seep in, freeze, and expand — widening the damage each winter. Don't over-seal, though: sealing too frequently builds up a soft layer that can track and wear.

When can you seal a brand-new asphalt driveway?

Wait 6 to 12 months after installation before the first seal. New asphalt needs time to cure — the oils in the mix must evaporate and the surface must harden. Sealing too early locks in those oils and prevents proper curing, which can damage the driveway. After that first seal, move to the regular 2–3 year cycle.

What maintenance does an asphalt driveway need beyond sealing?

• Fill cracks promptly. Crack filler is inexpensive, and stopping water intrusion early prevents potholes and base damage later.
• Protect the edges. Edges lack side support and crumble if driven on. Avoid parking within six inches of the edge, and backfill exposed edges with topsoil.
• Mind your winter tools. Don't set snow-blower scraper bars or metal plow blades so low they gouge the surface.
• Keep water draining away. Good runoff prevents pooling, which breaks down both the sealant and the asphalt over time.
• Patch potholes early. Professional patching is far cheaper than a full repave.

When should you resurface or replace instead of seal?

Sealing protects a sound driveway. Once you have widespread cracking, potholes, or a surface near the end of its life, resurfacing or replacement is the better investment — sealing won't fix structural failure. Most driveways are resurfaced every 15–20 years. If you're weighing a full replacement, our Ottawa asphalt driveway cost guide breaks down current pricing.
