The Benefits of Warm Mix Asphalt

At Lertiz & Busy Bee, we’re dedicated to not only supplying superior paving solutions, but providing leadership in the asphalt community. When new technologies arise, it is our goal to educate customers on the benefits we could bring to their paving projects. In this blog entry, we would like to explore the slew of advantages warm-mix asphalt has over conventional paving methods.


Warm-mix asphalt gained notoriety in Europe several years back for its positive impacts on the environment. Since then several communities here in the U.S. have adopted the process—including St. Louis—making it a popular alternative paving method. In 2011, over 200,000 tons of warm-mix asphalt was laid in the tri-county St. Louis area alone.


While some of the advantages may seem obvious, here is a basic rundown of the benefits warm-mix asphalt can bring.


    • Reduction in emissions: VOC and CO2 can be reduced by up to 60%. This process allows the contractor to lower the temperature of the asphalt by over 50 degrees, thus dramatically reducing the production of greenhouse gases.

 

    • Energy Savings: It’s quite common for asphalt plants to see a reduction of over 30% in energy costs.

 

    • Less Fuel: Because the temperatures run so much cooler, less fuel is used during the mixing.

 

    • Less Odor: Traditional asphalt emits not only a cloud of smoke, but also a very strong odor. If you’re running a business that is open to the public, do you really want them greeted this way? Warm mix asphalt produces less odor and yields little to no gas during the paving process.

 

    • Safer: Working with traditional hot-mix asphalt can be a very dangerous process. With warm-mix asphalt, not only will the contractor be exposed to less odor and smoke, but the risk of severe burns is reduced.

 

    • Faster: Because the compaction process is quicker, it allows roads and parking lots to open up to traffic sooner. For any business, time is money. For example, the longer a retail parking lot is closed the longer it serves as a burden to its customers.

 

    • Less Cracks: The binding process requires less ageing, which in return will increase the longevity of the asphalt.

 

For almost 30 years, the folks at Leritz & Busy Bee have been supplying the St. Louis area with innovative paving methods. If you have any questions regarding warm-mix asphalt, please feel free to reach out! Remember: for all your commercial and residential paving needs, think Lertiz & Busy Bee!

Even the most well-designed asphalt pavement system can’t escape the damaging effects of Mother Nature. How can facility owners or building managers know which preventative maintenance strategies are best for them?
In relatively new pavement showing the beginning signs of deficiencies such as surface cracking, preventative maintenance can add years to the life of an asphalt pavement system. Planning a pavement maintenance program early on can save both time and money.
Here are some helpful processes for maintaining your commercial asphalt system:
Crackfilling – Crackfilling typically refers to the process of blowing out and cleaning cracks prior to installation of a crackfiller material. This is also known as the “blow-and-go” method. If properly done, crackfilling reduces the infiltration of water into the crack, which protects the pavement system from being weakened by moisture. Crackfilling should be used for wider-type, non-working cracks.
Cracksealing – The cracksealing process involves an additional step that’s highly recommended for longer-term performance, and involves routing of the crack. Cracksealing includes grinding out the crack to a wider, 0.5-inch by 0.5-inch to 0.75-inch by 0.75-inch square, providing a reservoir for the rubberized crackseal material.
Surface Treatments – There are many surface-treatment options to choose from. General categories of surface treatments include: coatings (asphalt or coal tar emulsions), penetrating or rejuvenating sealers or aggreagate-based seals such as slurry seals, chip seals and micro-surfacing.
Be sure to call Leritz / Busy Bee to inquire if any of these practices will work for your commercial pavement system!
