How Long Does an Asphalt Parking Lot Actually Last?
Realistic expectations for South Dakota climates — and how to push your lot to the high end of its lifespan.
A properly installed asphalt parking lot in Sioux Falls should last 20 to 30 years. Whether you're closer to 20 or closer to 30 depends almost entirely on maintenance.
Year 1
Stripe the lot. Don't seal coat yet — let the binder cure and the oils flash off.
Years 2–3
First seal coat. Crack seal anything wider than ¼ inch.
Years 4–15
Seal coat every 2–3 years. Annual crack sealing. Patch failed sections as they appear.
Years 15–25
Consider an asphalt overlay if base is sound. Continue seal coating after.
The owners who get 30+ years out of their lots aren't lucky — they're consistent. Crack sealing every spring and seal coating on a fixed cycle keeps water out, and water is what kills pavement.
