Key Differences Between Tarmac and Asphalt Driveways
Tarmac and asphalt are two of the most used materials for driveways around the world. They look almost the same and share many similarities, but there are some key differences between the two materials.
If you are searching for the perfect material for building your driveway but cannot decide between tarmac and asphalt, the following post highlights the key differences between the two materials.
A brief into tarmac and asphalt
Tarmac is short for tarmacadam and is made with a layer of crushed stone or gravel is coated and mixed with tar and poured over the pavement base. The mixture is then run over by a vibrating roller to form a smooth surface.
Asphalt is similar to tarmac with one key difference, i.e., tar is replaced with bitumen, a petroleum distillation byproduct. Since there are lesser external materials, asphalt is hard-wearing compared to tarmac driveways in Kent.
Another alternative gaining popularity rapidly is asphalt concrete paving slabs in Kent, which is asphalt cement combined with grit or sand. This mixture is more expensive than either asphalt or tarmac but is extremely hard-wearing and durable. However, if you live in regions experiencing volatile temperature fluctuations, talk to your driveways manufacturer about the durability of asphalt cement in these areas.
Differences between tarmac and asphalt driveways
- Tarmac consists of bigger aggregates compared to asphalt, meaning the latter offers a better finish and a smoother surface that increases the tyre grip.
- Asphalt is reusable while tarmac isn’t. You can scrape asphalt off the surface and reuse it for a different project, making it an environmentally-friendlier alternative.
- When used over a large area, asphalt is cheaper than tarmac. Hence, it is preferred for building driveways, roads, and pavements.
- Tarmac needs more maintenance and takes damage from gasoline spills. Asphalt requires much lesser maintenance compared to tarmac over time and is more hard-wearing.
- Tarmac is more resistant to wear and tear from car tyres, while asphalt gets easily scuffed. On the other hand, asphalt is more resistant to extreme weather changes.
