Choosing an Asphalt Mix for Your Parking Lot

A few tips on choosing an asphalt mix for your business’ parking lot.

Choosing an asphalt mix for your parking lot is an important decision. Not all types of asphalt are the same, as doing some research in advance is a good idea to ensure you are satisfied with the results. Reaching out to a company offering parking lot maintenance is always a smart decision, as these professionals can guide you throughout the entire process in helping you determine the right type of asphalt mixes.

Asphalt Ingredients

An asphalt pavement consists of two main ingredients, which include aggregate (rocks) and bitumen. An aggregate includes any kind of rocky material. You can also choose the aggregate size, roundness, sharpness, and volume. Some aggregates work better in different mixes, and an asphalt contractor will know the best mixture to use to ensure your asphalt pavement will look great for many years. Mixing aggregate with bitumen will also vary based on your needs and the climate.

The lift thickness of a densely graded asphalt mix needs to be 2½ to 3 times the max aggregate size for the best results. Compaction also plays an important role in surface courses, as a mix with 3 percent or fewer air voids can be susceptible to shoving and rutting, while mixes with over 5 percent air voids can be susceptible to oxidation or raveling. A 4 percent air void is the best option due to it not being too open while also allowing for compaction in traffic times.

Cold Mix Asphalt

Cold mix asphalt blends oils and additives to create an asphalt mixture that can be stored and applied cold. Generally, using cold mix asphalt isn’t as effective as a hot mix, but installation methods are continuing to improve on an ongoing basis. Cold mix asphalt is often applied for repairing potholes or patching a parking lot. You can purchase cold mix asphalt to do it yourself, but in order to make sure that everything is done right, it’s always a better option to use a professional paving contractor. It saves time, too.

Warm Mix Asphalt

Warm mix asphalt is a newer method that combines hot and cold mixtures. One of the advantages of using warm-mix asphalt is that it can be used in cooler temperatures. It’s heated between 200- and 250-degrees Fahrenheit in the manufacturing process, and can be hauled for a greater distance, as well. Also, it’s more eco-friendly due to the use of fewer petroleum products compared to hot mix asphalt. Applying warm mix asphalt creates less smoke, dust, and fumes too, which is healthier for the workers.

Hot Mix Asphalt

Hot mix asphalt is a common mixture used in a variety of ways. An asphalt-paving contractor will heat the mixture and the materials between 280-325 degrees Fahrenheit and roll it on hot. Using hot mix asphalt is an excellent long-term option for parking lots due to its durability. Typically, hot mix asphalt is used during the warmer months, as cold temperatures can result in the base cooling too fast. However, the warm climate of Florida makes hot mix asphalt a perfect choice for most parking lots.
