TARMAC VS ASPHALT: What's the difference and how should commercial entities choose between the two?

Tarmac and asphalt are two of the most commonly used materials for paving roads, driveways, and parking lots. While they may look similar, there are significant differences between them in terms of composition, durability, and cost. In this article, we will explore the differences between tarmac and asphalt and provide guidance for commercial entities on how to choose the best option for their needs.

What is Tarmac?

Tarmac, also known as tarmacadam or macadam, is a type of pavement made from a mixture of crushed stones, gravel, and bitumen. Bitumen is a sticky, black, and highly viscous liquid that is extracted from crude oil. It acts as a binder, holding the stones and gravel together to form a hard, durable surface.

What is Asphalt?

Asphalt, on the other hand, is a type of pavement made from a mixture of sand, aggregate (crushed stone, gravel, or slag), and bitumen. Asphalt is produced in a specialized plant, where the materials are heated and mixed together to create a smooth and consistent mixture.

What’s the difference between Tarmac and Asphalt?

The main difference between tarmac and asphalt is the way they are produced. Tarmac is mixed on site, whereas asphalt is produced in a specialized plant. This means that tarmac can be laid more quickly and is more flexible, making it ideal for use on uneven surfaces. Asphalt, on the other hand, is more durable and resistant to cracking, making it ideal for use on high-traffic roads and highways.

Another key difference between tarmac and asphalt is their composition. Tarmac is made from crushed stones and gravel, which are cheaper and more readily available than the materials used in asphalt. As a result, tarmac is generally less expensive than asphalt. However, tarmac is also less durable and may require more maintenance over time.

How should commercial entities choose between the two?

When deciding between tarmac and asphalt, commercial entities should consider the following factors:

1. Durability: If the surface will be subject to heavy traffic or extreme weather conditions, asphalt may be the better choice due to its superior durability.
2. Cost: If cost is a major concern, tarmac may be the better choice, as it is generally less expensive than asphalt.
3. Maintenance: Tarmac may require more frequent maintenance than asphalt due to its less durable nature, so commercial entities should factor in the cost of maintenance when making their decision.
4. Appearance: While both tarmac and asphalt are black in color, some commercial entities may prefer the look of one over the other. Tarmac has a rougher texture than asphalt, which may be preferred for certain applications.

In conclusion, tarmac and asphalt are both effective materials for paving roads, driveways, and parking lots. When contacting a contractor for the works, commercial entities should consider factors such as durability, cost, maintenance, and appearance to determine which option is best for their needs. By weighing these factors carefully, commercial entities can make an informed decision that will provide them with a reliable and cost-effective pavement solution.
