There are hundreds of different types of variations of asphalt. However, most of them come from some mixture of 5 main types. Wondering which type of asphalt is right for you and your paving project? Here’s a brief rundown of the different types of asphalt.
Course graded asphalt is a type of mix which is coarse in texture. It often serves as a support for finer mixes used service lifts on driveways, parking lots, or roads. This is generally referred to as a “binder mixture”, or a base layer.
Another common type of asphalt is porous asphalt. Porus asphalt is an environmentally friendly solution to paving. The porous nature of this asphalt allows for water to travel through the paving job and into the ground where it naturally belongs.
This has led to porous asphalt being the first choice for many environmentally conscious businesses. There are also tax benefits that come from choosing an environmentally minded option.
Top layer asphalt, also known as hot surface mix, is easily the most commonly used paving material. These mixtures are generally heated to 300-350 degrees Fahrenheit. The mix is then used as a finish layer on top of the foundation.
This mixture is aesthetically pleasing due to the number of small stones that are compacted to form a tight surface appearance.
This option is slightly more fuel-efficient than hot surface mix. This is due in part to only being heated to 200-250 degrees Fahrenheit. Due to the lower heat, more binding materials must be used when laying this mix.
The primary benefit of this asphalt solution is its little impact on the environment. During construction, this mix uses less compactive effort and therefore emits less CO2. While this solution is slightly more expensive than other options, it has been a favorite choice among those seeking “green” solutions.
Cold mix is rarely used for large projects. This is due to its soft nature. Cold mix asphalt tends to stay soft no matter the temperature and therefore has a short lifespan. This has led to this mix being used mainly as a solution for potholes and other small repairs.
