When it comes to choosing the right surface for your driveway, road, or car park, you’ve probably heard the terms tarmac and asphalt tossed around a lot. They’re often used interchangeably, but here’s the truth—not only are they different materials, but they also perform differently.
If you’re wondering which one is right for your project, don’t worry. We’re going to break it all down in simple terms, just like the team at Steve Collins Surfacing would explain it. Let’s dive into the real-world differences between tarmac and asphalt so you can make a confident decision.
What Exactly is Tarmac?
Tarmac, short for tarmacadam, is one of the oldest types of road surfacing materials. It’s made by mixing crushed stone (or aggregate) with tar, which acts as a binder to hold everything together.
This mixture is laid hot, spread out, and then compacted to create a hard surface. It was a game-changer back in the day because it made roads smoother and more durable. Although it’s not as widely used in modern road construction, it still has a place in residential and private projects.
And What is Asphalt?
Asphalt is a more modern solution. Instead of tar, it uses bitumen, which is a sticky, black substance derived from crude oil. Like tarmac, it’s mixed with aggregates and applied hot, but the key difference is in the binder.
Asphalt is now the most popular choice for highways, driveways, airport runways, and car parks, thanks to its durability, flexibility, and cost-effectiveness.
Tarmac vs Asphalt: The Side-by-Side Breakdown
| Feature | Tarmac | Asphalt |
|---|---|---|
| Binder Material | Tar | Bitumen |
| Durability | Good for light use | Excellent for heavy use |
| Flexibility | More rigid | More flexible |
| Cost | Slightly higher | Generally more affordable |
| Appearance | Rougher texture | Smoother, darker finish |
| Weather Resistance | Can soften in extreme heat | Better heat and cold tolerance |
| Maintenance | Can crack or loosen stones | Easier and cheaper to repair |

Why Is Asphalt More Common These Days?
Asphalt has become the go-to surfacing material because it’s cheaper, quicker to install, and much easier to maintain. It also adapts better to varying temperatures, which means fewer cracks and potholes.
Contractors like Steve Collins Surfacing prefer asphalt for large-scale commercial jobs because it lasts longer under heavy loads—think lorries, buses, and hundreds of cars a day.
When Does Tarmac Make Sense?
Tarmac still holds its own in certain settings. If you’re resurfacing a private driveway or a rural path, tarmac can be a great choice. It gives off that classic, rustic look and is strong enough to handle regular household use.
It’s also a good option if you live in an area with light traffic and you’re going for a more traditional appearance.
Maintenance: Which One is Easier to Look After?
Good question. Tarmac needs a bit more TLC than asphalt. Because tar is more brittle than bitumen, it can crack over time, especially during winter freeze-thaw cycles or under heavy pressure. You’ll likely need to seal or patch it more often.
Asphalt, on the other hand, is a low-maintenance superstar. Potholes and cracks are easy to repair, and sealcoating every few years helps extend its life even further.
Looks Matter Too: Aesthetic Differences
Want that clean, modern finish? Asphalt is the winner. It’s darker, smoother, and gives off a polished look that works well in both residential and commercial settings.
Tarmac, while still visually appealing, has a rougher surface and a lighter tone. Some homeowners actually prefer this more natural, less refined look—especially for driveways leading up to country homes or cottages.
Installation Time: Which One is Faster?
Both materials can be laid relatively quickly by a skilled crew, but asphalt usually edges out tarmac here too.
Once asphalt is down, it starts to harden almost immediately and is often ready to use within 24 to 48 hours. Tarmac takes a little longer to cure fully, and weather conditions can slow it down.
So if time is a factor, asphalt might be your best bet.
Environmental Impact: Which One is Greener?
Here’s something you may not have considered: asphalt is more recyclable. Old asphalt can be dug up, reheated, and reused again and again. This makes it a more sustainable option overall.
Tarmac, with its reliance on natural tar, is harder to recycle and not as widely reused.
Steve Collins Surfacing is committed to environmentally friendly practices, so if you’re concerned about your carbon footprint, ask about recycled asphalt options—they’re both cost-effective and planet-friendly.
Cost Comparison: What’s the Price Tag?
While exact prices depend on the size and complexity of the job, asphalt is typically cheaper than tarmac.
Why? Bitumen is easier and less expensive to produce than tar. Plus, asphalt’s ease of repair and longer life span makes it more cost-effective in the long run.
That said, for smaller projects where aesthetics matter more than durability, tarmac can still offer great value.
Which One Should You Choose?
Alright, let’s sum it all up:
- Go with tarmac if you’re resurfacing a private driveway, don’t expect heavy traffic, and want a traditional look.
- Choose asphalt for larger areas, higher traffic, longer durability, and better weather resistance.
No matter which material you pick, proper installation is key. That’s where trusted professionals like Steve Collins Surfacing come in. They’ve got the experience, the tools, and the know-how to make sure your surface looks great and lasts for years.
Final Thoughts
Tarmac and asphalt both have their place in the world of surfacing, but they serve slightly different purposes. It’s not just about looks—it’s about performance, budget, and long-term value.
