What Is Warm-Mix Asphalt?

When my husband and I purchased our first home, the process was stressful, but we settled on one we liked enough to live in temporarily until we expanded our family. When moving time arrived, we both dreaded the expected stress. We ended up using a different real estate agent than we did the first time, and we made a great decision, because she had a lot of home remodeling knowledge! We were adamant on finally finding our "perfect" home this time. When she showed us homes that lacked features we desired that we would have "nixed" before, she let us know if the feature could be added, and usually it could! We are now in our new home that we had a few small renovations performed on after we bought it, and we love it! I want to help others by sharing some remodeling tips I learned on a blog!

What Is Warm-Mix Asphalt?

When it comes to paving with asphalt for a driveway or road, you have a few different options available. One of these options is warm-mix asphalt. This uses a special process for mixing, hauling, and placing the asphalt mixture. When there are slightly reduced temperatures used to product the asphalt mixture for pavement projects, it is referred to as warm-mix asphalt. Here are some things to know about this type of asphalt and why you might want to consider it.

The Difference Between Warm and Hot Mix Asphalt

The only difference between these two types of asphalts is in the production. When they are laid down and dry, they look and function exactly the same. With hot-mix asphalt, you need to have very high temperatures in order to create a fluid with the asphalt and mix it with the aggregate. This makes it more manageable and easier to place. With warm-mix asphalt, it uses chemicals, minerals, water and various additives so that it can be produced at a lower temperature.

The Benefits of Warm-Mix Asphalt

There are quite a few benefits to choosing warm-mix asphalt when you lay down a driveway, pathway or road. First of all, it is easier to manipulate and compact because of the lower viscosity in comparison to hot-mix asphalt. It will also reduce the cost of labor and installation, since it is easier to install. There is also a little more flexibility with how long it takes to install and what times of the day you can do it. In many cases, it is actually easier to do at night.

You will also improve the air quality of what labor workers are inhaling, making this a healthier option for people who provide the paving services. It will also reduce your own exposure to fuels and emissions.

The Drawbacks of Warm-Mix Asphalt

Before you choose warm-mix asphalt, you should also be aware of the potential drawbacks. The main drawback is in finding the right balance between the aggregates, moisture resistance, and the production temperatures. There may also be some additional costs you were not expecting, such as the cost of additives, patent fees, or equipment modifications.

Due to these drawbacks, it is recommended that you hire a professional paving company if you don't know about mixing at certain temperatures. This will ensure your warm-mix asphalt has the desired result. Find a paving company, like LSC Construction Services, Inc., that not only specializes in asphalt paving, but one that has used warm-mix asphalt before.
