Since there are two types of asphalt: hot-mix asphalt and warm mix asphalt, they both have different characteristics and use. Plus, they vary in strength and durability too. While many argue hot-mix to be better than a warm mix, is their claim justified? Let’s see!

In this blog, we’ll uncover the hot-mix and warm mix asphalt’s characteristics to help you pick the most suitable one for your project.

Hot-Mix vs. Warm Mix Asphalt

While asphalt is commonly used in building alleys, roadways, walkways, and private pavement, its different types have significant differences. Let’s distinguish all below. 


Hot-Mix Asphalt

Have you ever come across a paving team on the side of a road removing and then laying new asphalt? Did you notice the smoke emanating from the newly drawn asphalt? You are witnessing a hot asphalt coating.

Hot-mix asphalt is a mixture of bitumen and aggregates, such as gravel and sand, that must be heated before installed. Moreover, both application and installation of hot mix asphalt are done when it is hot but at 160° C and 130 ° C, respectively.

Warm Mix Asphalt

Although there is a higher sand content in warm mix asphalt, the strength does not reach that of the hot-mix. Besides, oils are added so that the binder remains malleable when cold.

Furthermore, there is no need to raise the temperature to apply cold asphalt. This is another explanation for the lack of solidity of this solution. And for this reason, it is usually used for repair or as a temporary coating.


Hot-Mix Asphalt

The hot-mix is suitable for circulated surfaces. It is mainly used for coating large plots (generally greater than 500 m²).

Besides this, hot-mix asphalt is the best material for highways, streets, parking lots (except underground parking lots because of ventilation), driveways, and crossings.

Reason: Hot-mixed asphalt cools quickly and allows rapid and long-lasting installation.

Lastly, the hot-mix is ​​more flexible than the warm mixture and has little or no cracking once applied.

Warm Mix Asphalt

Warm mix asphalt is mostly an option for repairing potholes or patches, making it a temporary paving solution.

Moreover, the cold mix is ​​not as strong as the hot-mix asphalt. It has a shorter lifespan and, therefore, is “pulled” only for small-scale repairs or temporary repairs until a hot-mix repair can be made.

Note: Although warm mix asphalt is used for asphalt repairing, it is not suitable to fill cracks in the pavement.
