When asphalt cures, it typically changes from a very dark black hue to a lighter, more matte gray color. Cured asphalt also won’t be tacky or sticky to the touch or emit any odors from the asphalt mix. Additionally, the surface of fully cured asphalt won’t deform under any pressure.

Three inches is a great thickness for a residential asphalt driveway that sees minimal to moderate traffic from cars, SUVs, and pickup trucks. However, a thicker driveway can better withstand the weight of a heavier vehicle, such as a trailer or a recreational vehicle. If you drive a heavy vehicle on a thin driveway, you risk cracking and damaging it.

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.

Paving is a part of hardscaping, so all paving is hardscaping, but not all hardscaping is paving. Paving involves laying down concrete or asphalt, while hardscaping can also include the use of paving stones, bricks, gravel, wood, and more. Hardscape features that involve paving are considered permanent and will increase your property taxes, while some other hardscaping features—like those involving bricks, gravel, and paving stones—will not affect property taxes. Paving also typically requires a permit, while hardscaping features considered temporary will not.
