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.

There’s no single best asphalt grade—it all comes down to where and how it’s used. Highways and heavy-traffic roads need something tough, like polymer-modified asphalt (PMA) or Stone Matrix Asphalt (SMA). Local roads and parking lots rely on the Performance Graded (PG) system, chosen based on climate. A PG 64-28 mix, for example, handles a broad temperature range while simpler, more cost-effective mixes are typically enough for residential driveways. The best grade of asphalt depends on traffic, weather, and your budget, which is why a professional’s input is always a smart move before making a decision.

At a depth of two inches, a ton of asphalt covers around 80 to 100 square feet. However, the thicker the asphalt, the less surface area it will cover. That’s why measuring correctly is essential when estimating asphalt needs and costs to ensure you get enough material to cover your entire driveway, patio, or other asphalt surface.
