What Are The Types Of Mix For Chicago Blacktop Paving Companies?

Black top paving is renowned for its durability, versatility, and stunning appearance. But did you know that there are different types of asphalt mixes that Chicago blacktop paving companies can use? While they all look nearly identical once cured, formula and manufacturing differences give each mix unique properties that contractors can leverage to produce five-star results.

What Is Black Top Paving?

Before we get into the various mixes that asphalt companies in Chicago use, let’s review some similarities. All black top paving is asphalt, a composite material composed of aggregates and a binder called bitumen. Formulas can also contain fillers and additives, such as sand, limestone, or specialty polymers.

However, all contain the same core makeup of aggregates and bitumen binder, which gives finished surfaces their signature black finish. What makes different mixes unique is variations in the formula and distinct manufacturing processes.

What Types of Mix Do Chicago Blacktop Paving Companies Use Most?

When planning a new paving project, your asphalt paving company will likely recommend a standard hot-mix asphalt. It’s, by far, the most commonly used material. During production, manufacturers heat the materials to temperatures of up to 350 degrees Fahrenheit. The bitumen becomes molten, binding everything together while creating a material that’s easy to lay.

It arrives at your site still hot, and your blacktop paving company will work fast to lay and compact the material before it cools too much. If hot asphalt cools to temperatures of 185 degrees or lower, it becomes too rigid to work with. The final product will suffer as a result.

Hot asphalt is a strong material that asphalt companies in Chicago use for everything from parking lots to roads and driveways. When compacted sufficiently, it becomes a dense yet pliable surface that can carry heavy loads without issue.

What Mix Might an Asphalt Paving Company Use for High-Traffic or Industrial Paved Surfaces?

Your asphalt company in Chicago may recommend dense-grade asphalt if you require substantial load-bearing capabilities. It’s a common choice for highways and industrial settings. As the name implies, this asphalt is denser than the standard HMA blacktop paving companies typically use.

These formulas contain aggregates of various sizes. The different sizes allow smaller pieces to lock into the gaps between larger ones. After thorough compaction, a skilled asphalt paving company can achieve a super-dense surface with virtually no air gaps.

When Do Chicago Blacktop Paving Companies Use Cold-Mix Asphalt?

During winter, an experienced blacktop paving company will likely use cold-mix asphalt (CMA) for repairs and patching. Rather than heating the materials during production, manufacturers combine everything at room temperature. They typically use an asphalt emulsion as the binder.

The emulsion dries and cures with air exposure, so heating is unnecessary. An asphalt company in Chicago may use CMA for wintertime repairs because it’s not affected by cooler temperatures. Using standard hot-mix asphalt isn’t possible when air and ground temperatures are cooler than 50 degrees. In cold weather, hot asphalt cools too quickly, compromising its integrity.

Cold-mix asphalt is a suitable temporary solution. A skilled blacktop paving company will use the material to perform emergency repairs, offering protection until they can return in the spring for more permanent solutions.

Is There a More Eco-Friendly Mix That Blacktop Paving Companies Can Use?

Warm-mix asphalt (WMA) is a good middle ground between HMA and CMA. To create it, manufacturers heat the ingredients to around 250 degrees. As a result, it uses less fuel and emits fewer emissions, helping lower a project’s carbon footprint.

WMA also performs well in cooler temperatures. When used correctly by experienced blacktop paving companies, it can produce results similar to standard hot mixes.

When Is It Appropriate for Chicago Blacktop Paving Companies to Use Porous Asphalt?

Porous asphalt has larger gaps between aggregates. It’s not a solid-surface material like the other options. As a result, water doesn’t simply sit on top. It can seep through the finished pavement and return as groundwater.

Asphalt companies in Chicago use porous asphalt in areas prone to flooding. It’s also a more environmentally conscious option because it can reduce pollution in storm sewers. The installation process for porous asphalt is different, but a properly finished paved surface can dramatically reduce the risk of flooding, erosion, and pollution.
