Thinking about upgrading your driveway? You’re not alone. A well-finished driveway does more than just give you a place to park it can totally change the look of your home’s exterior. Two options often compared side-by-side are tar and chip, and asphalt. They might seem similar at first glance, but they’re actually quite different in how they’re built, how they perform, and what they’ll cost you in the long run.
What Exactly Is a Tar and Chip Driveway?
A tar and chip surface (sometimes called chip seal) is made by spraying a hot layer of tar (bitumen) over a prepared base. After that, loose stones or gravel are spread over the top and then compacted. You end up with a textured, slightly rustic finish.
The process might sound simple, and in many ways, it is. That’s part of the charm. There’s no need for fancy machines or long drying times. The stones can even be chosen to match your home’s look, so it can feel a bit more personalised.
What About Asphalt?
Asphalt is what most people think of when they picture a smooth black driveway. It’s made by mixing bitumen with crushed stone or gravel, then laying and compacting it while it’s still hot. It creates a sleek, dark finish that looks neat and professional.
It’s more common in urban and suburban settings, especially on roads and car parks, but plenty of homeowners go for asphalt because it’s reliable and gives that polished appearance.
Cost Comparison
Tar and chip driveways usually come out cheaper than asphalt ones. That’s because they use less processed materials and don’t require as much heavy equipment to install. If you’re trying to get a decent surface without splashing out too much, this could be the more affordable route.
Asphalt driveways are more expensive upfront. The material costs more, and you’ll need a professional crew with the right tools. That said, if you’re after a more modern look or planning to use the driveway heavily, the higher price might be worth it.
Installation and Maintenance
Installation is one of the biggest differences.
Tar and chip can be laid fairly quickly, and because the surface isn’t perfectly smooth, it doesn’t show every little imperfection. Minor cracks or patches? They’ll blend right in. Maintenance is pretty minimal too. Every few years, you might want to re-chip the surface or touch up any bare spots, but it doesn’t need constant babysitting.
Asphalt, on the other hand, needs a bit more attention. It can crack over time, especially if the base shifts or water gets in. Sealing it every few years can help keep it looking good and prevent damage. It does give a very even, consistent look, but that comes at the cost of regular upkeep.
Durability and Longevity
This is where things get interesting.
Asphalt is tough. With proper maintenance, it can last around 20 years or more. It handles weight well, which is why it’s the go-to for roads and busy driveways. If you’ve got a few cars or even the odd delivery van rolling in, asphalt can take the pressure.
Tar and chip driveways don’t last quite as long usually 7 to 10 years before they’ll need resurfacing. But the upside is that resurfacing isn’t a huge ordeal. You just add a fresh layer of tar and stone on top, and you’re good to go. Plus, that slightly rough texture gives good grip, especially in wet or icy conditions.
Aesthetic Appeal
This one’s a bit personal.
Tar and chip has a more natural, country-lane sort of feel. The stones give it texture, and you can sometimes choose from different colours to suit the house. If your place has a rustic or traditional vibe, this style might complement it really well.
Asphalt is sleek. It’s clean, tidy, and very uniform. It pairs better with modern homes or places where you want a crisp, smooth finish. Some people prefer the neat look, while others think it’s a bit too stark. Totally depends on your taste.
Traction and Safety
Tar and chip surfaces have great natural traction. The stone texture means cars are less likely to slip in rain or frost. That can be a big plus if you live somewhere with a lot of wet weather or have a sloped driveway.
Asphalt is smooth. It still provides decent grip, especially when new, but over time it can get a bit slick particularly if moss or algae start to grow on it. You’ll want to keep it clean and possibly seal it regularly to prevent that.
Weather Performance
Tar and chip driveways can soften in extremely hot temperatures, though in cooler climates that’s rarely a problem. They also hold up well in winter, thanks to the natural grip of the stones. Snow and ice tend to melt quicker on the dark surface, which absorbs a bit of heat.
Asphalt can also soften under extreme heat, and it’s prone to cracking in freezing conditions unless it’s well-maintained. Sealing it helps, but water infiltration is always a risk if the surface gets damaged.
So, Which One’s Best for You?
That depends on what you’re after.
If you want something budget-friendly, quick to install, and with a more rustic look, tar and chip is probably your winner. It’s great for rural properties, longer driveways, or anyone who doesn’t want to fuss over constant upkeep. But if you’re leaning towards a modern finish, don’t mind a bit of maintenance, and need something that’ll handle heavy use, asphalt is the more reliable choice.
In my experience, it often comes down to the style of the house and how much you’re using the driveway. A quiet country home with a few cars? Tar and chip suits the vibe. A suburban spot with frequent traffic? Asphalt’s your solid pick.
