What Is Asphalt Paving?
Asphalt paving is the process of installing or resurfacing a driveway, road, or parking lot using hot mix asphalt. It involves building a brand-new surface from the ground up or replacing one that’s beyond repair.
You may need asphalt paving if:
Your current asphalt is cracked, crumbling, or has major potholes
The surface is uneven or pooling water
You’re building a new driveway or parking lot
A sealcoat won’t be enough to restore the structure
Asphalt paving is a larger investment than sealcoating, but it lays the foundation for a smooth, long-lasting surface that can last 10–20+ years with proper care.
What Is Sealcoating?
Sealcoating is a protective top layer applied over your existing asphalt. It’s like putting sunscreen or a waterproof jacket on your driveway—it doesn’t fix deep damage, but it protects what’s already there.
Sealcoating is made from a coal tar or asphalt-based emulsion and helps:
Shield against UV rays, rain, oil, and chemicals
Prevent surface cracks from turning into major issues
Restore that rich black color and curb appeal
You should sealcoat if:
Your asphalt is in good condition, but fading or drying out
You’ve recently filled cracks or done minor repairs
It’s been 2–3 years since your last sealcoat
Sealcoating is preventative maintenance that can dramatically extend the life of your asphalt.

Do I Need to Sealcoat My Asphalt Driveway or Repave It?
