Asphalt doesn’t last forever. Over time, your driveway will start to crack and corrode. Even with regular sealing, the smooth surface will eventually wear down due to damage from UV rays, salt, oil, gas and harsh weather.
When the cracks become unsightly and unsafe, there are two basic options: resurface or repave. Here, we’ll explore the differences between the two.
Resurfacing is a faster and simpler process than repaving. Essentially, you’re just putting a new asphalt driveway over the old one.
The first step in resurfacing is leveling the driveway to a even base. Then, a new layer of asphalt is applied, ranging in thickness from 1 1/2 inches to 3 inches. Finally, a heavy rolling machine is used to smooth and flatten the new layer.
Don’t confuse resurfacing with resealing, which is applying a protective coating to your asphalt. Resealing is a preventative measure designed to extend the life of your asphalt by protecting it from the elements. It is not a solution when your driveway needs repairing.
Life expectancy 8-12 years.
A lot cheaper but can get reflective cracks later in time.
Repaving is much more involved. It requires removing the old asphalt and starting fresh.
With repaving, a professional will come in and dig up all of your existing asphalt. Then, the soil below is filled, leveled and graded to ensure an even base. A layer of new gravel is placed above the soil and then compacted. Finally, the new asphalt is laid.
Life expectancy 15-20 years.
Always better to tear out, but its more expensive.
