5 Different Types of Asphalt

Asphalt aggregates are easy to customize and mix. There are hundreds of potential ways to mix asphalt materials to meet nearly any paving need. Most asphalt contractors maintain their own asphalt production facilities to create customized solutions for their customer base. Our experts on asphalt paving and sealcoating in Austin, TX, offer the following categories that most asphalt mixes fall into:

Coarse graded asphalt

Coarse graded asphalt is usually used as a base coarse or binder for supporting dense, fine-graded mixes used for surface lifts on driveways, roads, and parking lot pavement structures.

Warm mix asphalt

Warm mix asphalt, or WMA, is manufactured at temperatures between 200 and 250 degrees Fahrenheit. As a result, WMA asphalt production requires less in the way of fossil fuels than other asphalt types. Still, it requires additional binding materials to assist with pouring and spreading the materials at lower temperatures. As a result, warm mix asphalt is usually less expensive to produce than other materials like hot mix asphalt.

Hot mix asphalt

Hot mix asphalt (HMA) is a term used to describe asphalt mixtures that are heated and poured at temperatures ranging from 300 to 350 degrees Fahrenheit. This asphalt is the most commonly used type on the market.

HMA can be separated into three categories: open grade mixes, stone matrix asphalt, and dense-graded mixtures. Dense-grade mixtures are placed in classes based on the sizes of the aggregate utilized and are separated into two subcategories that include course-graded asphalt and fine-graded asphalt. Dense-grade mixtures falling into the fine-graded subcategory contain an increased percentage of small stones and sand compared to course-graded options. HMA is often used for paving highways, interstates, and other high-traffic roadways.

Cold mix asphalt

This type of asphalt remains soft in cool temperatures and assists with repelling moisture. It is primarily used to repair potholes. Contractors can create this asphalt at nearly any temperature because the manufacturing process is relatively straightforward.

Porous asphalt

Porous asphalt is one of the most environmentally friendly paving options available on the market. It is touted as an Environmental Protection Agency best practice paving, and using it for your paving project can often provide you with tax benefits. The term porous refers to the many tiny holes within the asphalt materials that provide an environmentally friendly and sustainable solution for managing stormwater. As a result, the water can travel through the asphalt materials and into the ground, where it can undergo the natural water cleansing process.

These are the four main types of asphalt available on the market.
