Get matched with top asphalt driveway pros in Obion, TN

Gravel is one of the few driveway materials that can handle rain the second it’s installed. Unlike asphalt, which needs days to set, or concrete, which requires weeks to cure, gravel is ready as soon as it’s compacted. It’s naturally permeable, allowing water to drain straight through—with no risk of pooling or surface damage. Gravel driveways are one of the most affordable, at $1 to $3 per square foot, and can also last upward of 100 years.

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.

Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.

Like all driveway materials, asphalt can crack in the wrong conditions and with age. Many things can cause asphalt to crack, including shifting soil or settling under the foundation. Other common causes are driving oversized vehicles on the asphalt, tree roots, and using rock salt during the snowy season. Proper installation and sealing the driveway every 10 years can help prevent cracks.
