The Benefits of Porous Asphalt

As leaders in the St. Louis asphalt community, we believe it is imperative that we continue to bring forth new and innovative solutions to the pavement industry. One solution we’ve pushed forward involves runoff on paved surfaces. Runoff has always been a challenge for many property owners and facility managers, but it doesn’t have to be Porous asphalt, an application used mainly in parking lots, is made up of stone, asphalt, and gravel that are combined to create a permeable surface. While this technique has existed since the 1970s, it was slow to take off due to many poor installations.

At Leritz & Busy Bee, our teams of professionals have been installing porous asphalt for a number of years, and let us tell you, there are a multitude of benefits.

  • Less runoff: As you know, the porous surface is pervious in nature and can infiltrate up to 80% of annual runoff when installed properly. So how can this benefit you monetarily, you ask? Well, because your annual runoff will be drastically reduced, the need for a large detention basin will as well. These storm basins are not only expensive, but require a large piece of land to build.
  • Longevity: Research shows that even after 20 years, porous paved surfaces show little to no cracking or splitting. We have noticed that the asphalt wears well and drains effectively for several years. Even though 20 years seems to be the average lifespan, it is not uncommon to see a porous surface last over 30 years. It’s all contingent upon the initial installation and whether or not the surface was properly maintained.
  • Environmental: Porous asphalt offers up a variety of environmental benefits including reduction of storm system basins and cooler asphalt temperatures. As we mentioned, 80% of runoff after a rain storm will pass through the asphalt, thus reducing the need for storm basins. Also, because porous requires less energy to manufacture it will significantly reduce emissions, odor and smoke.
  • Cost-Efficient: The overall lifetime cost of a paving project is greatly reduced when choosing porous asphalt. Not only will it last you at least 20 years, it will not require the need for a large storm basin. In some cases, the basin can be eliminated all together, thus saving you money and giving you more space.

The Benefits of Porous on a Slope

In a previous blog entry, we explored an array of benefits that porous asphalt could bring to your next paving project. While we touched briefly on many of the benefits, we didn’t dive into examples of when porous could be put to proper use.


For many facility managers, controlling the runoff after a heavy rain can be a very trying task. The addition of porous asphalt to your storm management system will not only reduce your annual runoff by 88 percent, but will help eliminate those annoying puddles in the parking lot.


The way it works is quite simple. Once the old asphalt is removed, a series of perforated pipes are incorporated within an open-grated crushed limestone base in an effort to route the runoff to the closest storm drain. After construction of the base and piping, it is time to lay the asphalt. Because porous asphalt is permeable in nature, it allows the water to drain through the surface, down into the storm water management system. Porous asphalt will significantly reduce those pesky water puddles and extend the life of your asphalt. Unfortunately, porous asphalt is not designed for patching small areas.

Asphalt: The cure for hydrostatic water

With everyone battening down the hatches in preparation for fall weather; we thought it would be appropriate to explore one of the many effects from torrential rainfall: hydrostatic water pressure. Hydrostatic water pressure is most common in basements, but its wrath can be seen all over… including your parking lot!


One of the biggest destroyers of asphalt is moisture. When moisture accumulates below the surface it compromises the strength of the stone base and softens the underlying soils. The simplest, most efficient way to solve this problem is with the addition of under-drains – commonly referred to French drains in the industry. How does it work, you ask? Let us explain…


Once the old asphalt is removed we dig a trench, usually to a depth of 24”, and install fabric-wrapped perforated pipe. The trench is then filled with open-grated stone. This allows the ground water to find its way to the pipe and out from beneath the pavement. Finally, the asphalt surface if replaced. Depending on the location of the French drain, porous asphalt may be installed to eliminate water ponding issues as well.


French drains can—if properly installed—extend the overall lifespan of your asphalt.

Prepping for pavement

At Leritz & Busy Bee, we provide specialized asphalt solutions to the commercial industry. Our paving process is prompt and cost-efficient, thus saving you time and money. How have we been able to do this, you ask? Two words: surface prep.

Once you have chosen an asphalt application it is time to begin phase one of the pre-pavement process: surface preparation. If the area is new, it is important that we dig a space deep enough to accommodate not only the asphalt, but the gravel base as well.

Speaking of the gravel base, it is vital that your base is the proper thickness. Asphalt gains strength from the rock base beneath. Determining the proper rock thickness will give your area a solid foundation and increase the overall lifespan of your pavement. A minimum of 6” of rock is recommended; however increasing your rock base will only make your pavement more durable. Also, it is very important that we compact the rock before we begin paving. Proper compaction equipment is essential, which will help prevent early settling and cracking of your pavement.

Also, please be vigilant in ensuring your contractor is applying a gravel base. Many “fly by night” contractors will try to cut corners in effort to save money, but a gravel base can simply not be forgotten.

Paving the way on St. Louis trails

Who doesn’t love springtime in St. Louis? Cool nights at the ballpark, romps with the dogs in Forest Park and long bike rides down the Katy Trail… it doesn’t get much better than that! Speaking of the Katy Trail, have you noticed that the majority of walking/biking trails around the area are paved with asphalt? Yep, it’s true! Asphalt wins again!

If you’re not familiar with the world of asphalt, let us explain how opting to pave the trails with asphalt benefits everyone in the long run.

#1 Weather Resistant: Snow and ice during the winter months can wreak havoc on roads concrete pavement. However, asphalt is far more weather resistant. The petroleum content allows the asphalt to expand and contract without sustaining serious damage. If damage is sustained, the cracks can be easily fixed using emulsified liquids.

#2 Quick Maintenance: If you’re like many St. Louisans, you enjoy your local trail many times each week. If your trail goes under construction for repairs or expansion with concrete it could be weeks before it will reopen. With asphalt, the construction process is completed in literally a fraction of the time.

#3 Cost Efficient: Most local trails are either maintained by tax dollars or private funding. With that being said, wouldn’t it be a better use of your dollar to go with the option that is not only more durable, but cost-efficient, too?

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.

Full Depth Reclamation: Paving the Way to the Future

As corporations continue to inquire about green products and services, it is vital we develop solutions that are not only effective but realistic for the average business owner to implement. At Lertiz & Busy Bee, we have adopted a proven practice that will not only lessen our impact on the environment, but increase your bottom line!

Full depth reclamation is a process in which old asphalt pavement is recycled and reused to help create a new surface. The way it works is quite simple: the old existing asphalt is pulverized and treated to create a solid, stable base.

You might be asking yourself: “Sounds great, but it’s probably more expensive, right?” Wrong! Unlike the conventional method, there is no need to make a trip to the landfill. We use 100% of the existing surface, allowing us to cut down on material costs and reduce project timelines.

Here is a simple breakdown of the four step process:

  • Pulverize – Using a special machine called a Reclaimer we pulverize the old asphalt and blend it with the rock base. It has been proven through the years that reclaiming old asphalt is a much more effective way to build a solid core base.
  • Treat – During the second phase of the process we treat the base with special additives such as lime or calcium chloride. Once treated, it is time for another round of pulverizing to help further compound the base.
  • Re-grade – The re-grading will allow us to shape and reform the base to better fit the contour of the roadway or parking lot.
  • Pave – Once the base is shaped and compacted it is time to start paving. This is the only step in the process that is similar to the conventional method. The asphalt used is a standard blend that would be used in any traditional pavement project.


Reclaiming asphalt is an age-old practice with a proven track record of not only cutting down material costs, but ensuring projects are completed in a timely fashion.

The World Famous Asphalt Museum

Did you know that there is a world famous Asphalt Museum? Well neither did we – but there is!
The Asphalt Museums is actually more of a display located in the California State University – Sacramento office of Professor Scott Gordon. Gordon is a self-professed collector of asphalt and began the “museum” in the early 1990s.
The collection houses samples of asphalt form all over the world including one from the longest stretch of Route 66 in Arizona as well as samples from as far away as Tanzania, Italy and Scotland. After the museum became an internet phenomenon – it was listed for some time as a Wine Country attraction on Yahoo, people began sending in the samples from all over the world.
Gordon jokes that the museum is more of an internet joke than an actual museum but he counters that there are asphalt enthusiasts out there. The website not only details the collection but highlights art exhibits featuring asphalt as well. While it may not be an actual museum, we think it’s pretty neat.
