Asphalt Paving vs. Resurfacing: Which One Do You Actually Need?
If your driveway or parking lot is in rough shape, you have two real choices: resurface (a fresh layer on top) or fully repave (tear out and replace). Picking the wrong one wastes thousands of dollars.
Resurfacing (asphalt overlay): when it works
Resurfacing lays a new 1.5"–2" layer of hot-mix asphalt on top of your existing surface. It's roughly half the cost of full replacement and lasts 8–15 years.
Good candidates: the sub-base is still solid, drainage is fine, cracks are surface-level, and the existing surface isn't more than 20 years old.
Full replacement (repaving): when it's the only option
If you have potholes, alligator cracking across large sections, standing water, or a failing sub-base, an overlay will fail in 1–2 years. The cracks telegraph right through.
Full replacement means removing the old asphalt, regrading and recompacting the base, then laying new asphalt. Lasts 20–30 years with proper maintenance.
Cost comparison (NJ averages)
Resurfacing: $3–$5 per square foot. A typical 2-car driveway runs $1,800–$3,500.
Full replacement: $7–$13 per square foot. Same driveway runs $4,200–$9,000.
Commercial parking lots vary widely based on square footage, sub-base condition, and ADA work needed.
