Asphalt is an incredibly common material used for paving roads, driveways, and parking lots because of its durability and low cost. However, not all asphalt mixes are created equal, and different projects require different types of mixes to ensure the desired results. In this blog post, we’ll go over the three main types of asphalt mixes and what type of project each one is best suited for, so you can make an informed decision on which mix is right for your next paving project.
The first type of asphalt mix is known as dense-graded asphalt. This type of mix has small aggregates and a high asphalt content, which means it’s very strong and durable. Dense-graded asphalt is best suited for high-traffic areas like highways, airport runways, and industrial parks, where heavy machinery and trucks will be driving on the pavement. Its durability also makes it a great choice for harsh climates with frequent freeze-thaw cycles, like Wisconsin.
The second type of asphalt mix is called stone matrix asphalt. Stone matrix asphalt, or SMA, is a mix that has a higher percentage of coarse aggregates than dense-graded asphalt, which creates a rougher surface. SMA is used mainly for roads that have to withstand heavy rain and runoff because its rough surface provides better friction. SMA is also great for areas with steep slopes and curves, as it can help prevent accidents by providing better traction.
Finally, the third type of asphalt mix is porous asphalt. Porous asphalt is made with larger aggregates than traditional asphalt mixes, which creates spaces for water to drain through the pavement instead of sitting on top of it. Porous asphalt is great for parking lots because it reduces the amount of runoff water and reduces the risk of flooding. Porous asphalt can also be used to reduce the urban heat island effect, as it absorbs and releases heat unlike traditional asphalt.
Choosing the right asphalt mix for your project is crucial to ensure a long-lasting, effective result. Whether you’re paving a highway, a winding mountain road, or a parking lot, each type of asphalt mix has its own unique benefits and purposes.
