What Are The Different Types Of Asphalt? What Makes Them Different?

Construction & Contractors Blog

Did you know that there are actually three types of asphalt? Most people don't realize that the same substance that is found on roadways and on their driveway is actually created three different ways and are used for several different types of projects. What are the three different types of asphalt and what makes them different?

Hot Mix

The first type of asphalt is known as hot mix asphalt. Hot mix asphalt is a mix of coarse aggregate stone, sand, and petroleum-based cement that is heated and then poured at high temperatures to create your driveway, highways, interstates, and roads in your city or town. This is the most recognized type of asphalt paving and widely used by most contractors because it is waterproof and highly flexible.

It is able to repel water and is weather resistant, meaning wind, rain, and hot or cold temperatures shouldn't affect the surface, and any wear or damage would come gradually over time. The mixture heats up quickly and cools down to a workable temperature and solidifies fast, making it the most popular mixture to use.

Warm Mix

The next type of asphalt is called warm mix. This mixture is used during the winter or colder months for repairs, and it can be used more effectively in overnight projects. It is made at lesser temps ranging into the lower hundreds, and it tends to cool more slowly than a hot mix does. It is more cost effective to make for companies and uses far less fossil fuel materials than hot mixes during the creation process. It is flexible in its use, and while not as widely used as hot mix asphalt, it does see quite a bit of use.

Cold Mix

The most affordable of the three types of asphalt is cold mix asphalt. It doesn't require any kind of heat at all to make it. It is typically used to repair cracks in existing asphalt and to fill in potholes on roadways. The repairs tend to be smaller than what is repaired using the warmer mixes; and, cold mixes are generally used as a temporary fix until a more comprehensive repair is done.

When contractors determine which mix of asphalt to use for a repair or new roadway, they will see how busy that street is and what type of traffic will travel that road. They also take into account how much noise reduction they need and how durable the road must be over time.
