Get matched with top asphalt driveway pros in Newcastle, WY

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.

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.

Cobblestone is just one of many driveway materials. Other, more economical, albeit less elaborate options include concrete, asphalt, and gravel. 

If you want a material that most closely resembles cobblestone, your best option is bricks or pavers. Both cost anywhere from $10 to $50 per square foot and can be laid in all kinds of patterns. Depending on the type of paver you choose, you can also get a good bang for your buck by investing in durable natural stone.

Your city or county will have guidelines about the minimum and maximum width and length of private roads. The average private road is 12 feet wide, and length, of course, depends on your property. Requirements also depend on the amount of traffic and types of vehicles your road experiences. Check with local ordinances before planning a road on your property.
