How Long Does an Asphalt Driveway Last?

Straight answer for Shreveport-area homeowners planning asphalt work. No sales-y bloat — just what we’d tell a friend.

The Real Answer

A professionally-installed asphalt driveway in Shreveport, maintained on schedule, lasts 18–22 years before it needs a mill-and-overlay, and 30–40 years total lifespan including the overlay cycle. An installed-badly, never-sealcoated driveway lasts 7–10 years to failure. The variable is the maintenance discipline, not the material.

For comparison: concrete driveways nominally last 30–40 years but often show visible cracking within 5 years on our expansive clay, at which point the aesthetic life is arguably shorter than a well-maintained asphalt driveway.

What Kills Asphalt Early

Three main killers, in order of impact: skipping the sealcoat schedule (binder oxidation accelerates dramatically without it), water intrusion through unsealed cracks (once water reaches the base course, clay-driven crack propagation takes over), and poor initial install (missing base course, no geotextile, mat below spec thickness). Address all three and you get the 18–22 year outcome. Miss any one and you shorten life by years.

Weather is a background factor but not something you control. What you control is install spec (see proper install), sealcoat cadence (every 3 years — see cadence), and crack sealing before cracks grow past 3/4".

Life-Extension Interventions

Beyond the 18–22 year first-life, a mill-and-overlay at that point adds another 10–15 years, taking total life into the 30–40 year range. After two overlays, industry rule of thumb says tear out and start over — the base structure is old enough that a third overlay stops delivering value. For a single-family homeowner, this typically means one full replacement and one overlay over 35–40 years of home ownership.
