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 Leritz & Busy Bee Way – Minimal Operational Impact

At Leritz & Busy, we truly understand the importance of maintaining a high level of productivity… regardless of the industry. That is why we are committed to offering asphalt solutions that have minimal impact on business operations. How do we do this, you ask? One word: planning.

Last year, Manheim St. Louis Auto Auction hired us for repair and replacement work at their 72 acre site in Bridgeton, Missouri. The complex houses thousands of vehicles and is open to buyers and sellers seven days a week. Closing the lot for an extended period of time would not allow them to fully operate, thus resulting in a loss of revenue.

In order to minimize the disruption of their operations, our team developed a strategic plan to complete the project. This plan included working directly with their facility management team to coordinate their daily activities so we wouldn’t interfere with the day-to-day operations.

As a result of our strategic planning, the Lertiz and Busy Bee team was able to complete the project on schedule with minimal impact to the ongoing business at Manheim St. Louis Auto Auction. Because the project was completed in such an efficient manner, we have been called upon to perform asphalt paving and repair work in other areas of the facility.

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.

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.

Reclaim Your Asphalt

We’ve written before on the topic of asphalt sustainability, asphalt is one of the most recycled products in the United States. This recycled material can then be used for future projects.

Recycled asphalt is often referred to as reclaimed asphalt pavement or RAP. The material is removed and reprocessed from pavements that are currently undergoing reconstruction or resurfacing. The material then either undergoes a cold milling process or a full depth removal and crushing.

Large scale organizations, such as the Missouri Department of Transportation (MoDOT) use reclaimed asphalt and recycled tear-off shingles in many of their projects. The organization estimates that in 2009 they saved $20 million on resurfacing projects in which recycled asphalt was used. In addition to the substantial cost-savings, the use of reclaimed and recycled materials decreased the amount of items headed to Missouri landfills.

Cleaner Water from Asphalt

A new white paper from the Asphalt Pavement Alliance sheds light on the beneficial effects asphalt pavements can have on water quality.

According to Dr. Howard Marks, principal author of the report “Cleaner Water with Asphalt Pavements,” the green benefits of 100 percent recyclable asphalt pavement might be surprising to some. Asphalt pavement s are clean and environmentally beneficial for improved stormwater management, clean drinking water and reduced roadside pollution.

One common misconception is that asphalt pavements leach petroleum into the earth, this is not the case. In fact, asphalt pavements have several eco-friendly benefits including the fact that smooth asphalt pavements save fuel and overall has a small carbon footprint compared to other paving materials.

Harnessing the Heat

In the dog days of summer you may feel the heat radiating off of pavement surfaces, can we find a way to harness the heat for good?

Thermal energy has been used for decades to warm eco-friendly pools, but tech company Novotech has patented an idea known as Roadway Power Systems. Michael Hulen, Novotech founder, says the technology has many practical applications. For example, a hotel with a large parking lot could run a piping system under the pavement, using the heat absorbed by the asphalt to heat water for laundry and shower, reducing energy consumption. The captured heat can also create electrical power by creating high-pressure steam. This steam can spin a turbine and produce kilowatts or even megawatts of power.

Unlike conventional solar systems, asphalt retains heat even after the sun goes down, therefore it could continue producing energy even after sundown. Novotech estimates that a two-acre parking lot could cool a 30,000 square foot building. While the technology is still in the beginning phases and has yet to be rolled-out in large scale, it certainly seems to have promise in harnessing the heat!

Warmin’ Up with Warm Mix Asphalt

The temperatures may be heating up, but the hot talk in the pavement industry is warm mix asphalt (WMA). The new technology is gaining acceptance at an unprecedented rate, 44 of the 50 states have completed WMA jobs.

The wide acceptance of WMA has been so quick because of the numerous advantages it has over hot mix asphalt, these include:
• Less environmental impact
• Less fuel use by the mixing plant
• Decreased wear on the mixing plant
• Longer haul distances, creating an extended paving season
• Increased time for compaction, leading to better densities
• Longer pavement life

Warm mix asphalt is made by using a variety of products and process to replace the heat normally necessary to produce asphalt mix. Keeping the mixing temperatures low, 50 – 100 degrees Fahrenheit less than required for traditional asphalts, results in reduced emissions and fumes and can also lead to a significant energy savings.

While the benefits are obvious, WMA does present some challenges. First, the industry hasn’t fully adapted and some job specifications do not provide for using WMA technology. With new technologies come unknowns, more studies are needed to further investigate the benefits, long-term suitability and sustainability of warm mix asphalt. For more information on WMA, visit
