The Science of Asphalt Paving: Understanding the Process and Materials

Can you believe that Canada has more than a million kilometres of roadways?

The most reliable roads use asphalt. This type of paving is a common technique used by anyone who wants durable and long-lasting surfaces. Beyond roads, asphalt paving is great for parking lots, driveways, and other construction projects.

Whether you're planning a commercial or residential asphalt paving project, understanding the process and materials involved is crucial. Keep reading for a comprehensive guide on the science of the asphalt paving process.

Types of Asphalt Paving and the Process

Two main types of asphalt paving are hot-mix asphalt and cold-mix asphalt.

Hot mix asphalt is often used in construction projects. It's made by heating aggregates and bitumen. Once they've reached high temperatures, the experts mix them together at a specialized plant.

The mixture gets taken to the construction site and laid down while still hot. It's worth the investment because hot mix asphalt gives a smooth, lasting surface that can withstand heavy traffic and even harsh weather.

Are you wondering what cold mix asphalt is? Although it's a less common solution, it involves using ambient temperatures rather than heating the ingredients. You'll find cold mix asphalt in cases of temporary repairs or construction projects of a smaller scale.

Asphalt Paving Materials

Asphalt paving involves several main materials. These include aggregates, bitumen, and various additives.

Aggregates are a combination of crushed-down rocks, sand, and gravel. It's used for structural support and stability.

Bitumen works as a great binder because of its stickiness. Additives are chemicals that experts add to the asphalt mixture. They boost the pavement's performance, durability, flexibility, and crack resistance.

During installation, the asphalt mixture is spread to create a smooth surface. Experienced contractors use advanced equipment and techniques, such as laser-guided grading and compaction machines.

After installation, a curing process allows the mixture to harden and set. This is when the asphalt pavement loses some of its volatile oils and flexibility.

Benefits of Asphalt Paving

Since asphalt paving can last long if done well, you can see it as a long-term investment.

Plus, it's easy to maintain. All you need is seal-coating and resurfacing every now and then for it to last many years.

Without proper maintenance and repairs, asphalt paving safety can nosedive. This is why you should inspect for signs of cracks and potholes and nip them in the bud before they become an issue.

Remember that asphalt paving is even less expensive than other pavement materials. The installation and curing process is often quick and easy.
