Get matched with top asphalt driveway pros in Caruthersville, MO

Asphalt and tarmac are not the same thing. Traditional tarmac, short for tarmacadam, uses tar as a binder to hold crushed stone together. Asphalt uses bitumen—a byproduct of crude oil—to bind aggregate. Though tarmac was once a go-to for roads, asphalt has become the modern standard. And these days, most surfaces referred to as “tarmac” are actually asphalt. So, while the names may overlap, the key distinction lies in the binder—tar for tarmac and bitumen for asphalt.

With proper maintenance, asphalt milling driveways can last 30 years or more. Over time, you’ll need to regularly sealcoat your driveway. You should also have your driveway inspected every few years and make any repairs as soon as they are necessary; this will prolong the lifespan of your driveway.

Whether you should resurface or replace your asphalt driveway heavily depends on its condition. If the foundation is solid and the damage is minor, resurfacing is your best bet because it’s more affordable and faster than replacing the driveway. But if your driveway has foundational problems and/or severe damage, like large, deep cracks and potholes, then it makes more sense to replace it. 

While some areas may allow for a slope of up to 20%, this is often the maximum slope for driveways, with a few exceptions of up to 25%. Other regions may have a maximum of 12%, 15%, or 18%, so check with your local building department to ensure you’re laying a driveway that is up to code for your location.
