If you’re planning a driveway, parking lot, or road surface, you’ve likely come across the terms tarmac and asphalt. At first glance, they might seem like two words for the same thing. But if you dig a little deeper, you’ll find some key differences that could affect your project in a big way.
In this article, we’ll break down what tarmac and asphalt are, how they’re used, and which one might be the better choice for your needs. Whether you’re a homeowner or a commercial property owner, this guide will help you make an informed decision.
What is Tarmac?
Tarmac, short for tarmacadam, is a road surfacing material that’s been around since the early 1900s. It was invented by Edgar Purnell Hooley and revolutionized road building.
Tarmac is made by combining crushed stone with tar. This mixture is then laid down and compacted while hot to create a hard, smooth surface. The tar acts as a binder, holding the stones together.
What is Asphalt?
Asphalt is a more modern alternative to tarmac. It’s made using bitumen—a sticky, black by-product of crude oil—combined with crushed stone and sand. Like tarmac, it’s laid and compacted while hot.
Although similar in appearance, asphalt tends to be more flexible and durable over time. That’s one reason why it’s become the more popular choice for road construction and driveways today.
Tarmac vs Asphalt: Key Differences
| Feature | Tarmac | Asphalt |
|---|---|---|
| Binder | Tar (naturally occurring) | Bitumen (oil by-product) |
| Durability | Moderate | High |
| Cost | Generally higher | More affordable |
| Flexibility | Brittle | Flexible |
| Maintenance | Prone to damage | Easier to repair |
| Use Cases | Driveways, older roads | Roads, car parks, commercial surfaces |

Which is More Durable: Tarmac or Asphalt?
When it comes to long-term performance, asphalt tends to win. It’s designed to be more weather-resistant and flexible, which means fewer cracks and potholes over time. That flexibility is crucial in areas with heavy traffic or frequent freeze-thaw cycles.
Tarmac, while solid and strong, doesn’t have the same level of elasticity. It can crack under pressure, especially with heavy vehicles constantly driving over it.
What About Maintenance Needs?
Let’s face it—no surface lasts forever. But some are definitely easier to maintain than others.
Tarmac can degrade quickly if not sealed regularly. Exposure to sunlight and water can cause the tar to dry out, leading to loose stones and a rough surface. Repairs can be more time-consuming and expensive.
Asphalt, on the other hand, is relatively low maintenance. Potholes can be patched quickly, and surface sealants help extend its life. That’s why asphalt is the go-to for busy roads and high-traffic areas.
Cost Comparison: Is One Cheaper Than the Other?
Cost is often a deciding factor. Asphalt usually comes out ahead here. Because bitumen is cheaper to produce than natural tar, asphalt tends to be more affordable—especially for larger projects like commercial parking lots or long roads.
Tarmac, while a bit more expensive, still has its place. It might be the right choice for residential driveways or smaller-scale applications where aesthetics and tradition play a role.
Appearance and Texture: What Looks Better?
Looks matter—especially when you’re dealing with something as visible as your driveway.
Tarmac has a classic, slightly rugged appearance. It tends to be a bit lighter in color and has a coarser texture.
Asphalt looks smoother and darker. It gives a sleek, professional finish, which is why many businesses prefer it for car parks and commercial entries.
Environmental Considerations
If you’re trying to reduce your carbon footprint, the production process matters.
Tarmac relies on tar, which is less eco-friendly and harder to source today. Asphalt production is more controlled, and recycling is much easier. In fact, asphalt is one of the most recycled construction materials in the world.
Steve Collins Surfacing often uses recycled asphalt in their projects, helping clients get a high-quality finish while staying eco-conscious.
When Should You Choose Tarmac?
Despite its limitations, tarmac still has value. You might want to consider it if:
- You’re restoring an older property where authenticity matters
- You like the look and feel of traditional road surfaces
- The area has light traffic and won’t be subjected to heavy loads
Tarmac can still give you a strong, long-lasting surface with the right care and installation.
When is Asphalt the Better Option?
For most modern applications, asphalt is the clear winner. It’s more flexible, durable, and cost-effective.
Here’s when asphalt makes sense:
- Driveways with frequent car use
- Large car parks and commercial forecourts
- Roads and cycle paths
- Anywhere with heavy or continuous traffic
Asphalt also holds up better under harsh weather and is easier to repair, which means fewer headaches in the long run.
Installation Time and Curing
Both tarmac and asphalt need time to cure, but asphalt usually sets a little faster. With the right crew—like the team at Steve Collins Surfacing—you could be using your new surface within 24-48 hours.
Tarmac might need a bit longer, especially in colder or damp conditions. Make sure you account for curing time in your schedule, especially if you’re resurfacing a driveway or commercial entrance.
Conclusion: Which Should You Choose?
There’s no one-size-fits-all answer. The best choice depends on your needs, budget, and how the surface will be used. That said, if you’re looking for a long-lasting, low-maintenance, and budget-friendly option, asphalt usually comes out ahead.
Tarmac, though, still offers charm and character in the right setting.
Whether you go with tarmac or asphalt, what really matters is who installs it. Proper groundwork, compaction, and finishing will determine how long your surface lasts. That’s why working with experienced professionals like Steve Collins Surfacing is key. They’ve been laying high-quality tarmac and asphalt surfaces for years, and they know exactly how to get the job done right.
