Is it time to replace the pavement at your business? If so, you should consider porous asphalt pavement. This is a permeable type of pavement, which means that water can pass through it. It is significant because it can trap pollutants from storm water by soaking them in. This reduces runoff, which improves the quality of the water supply. Read on to learn more about this type of paving, and reasons it could be right for your business.
How does it work?
Imagine running water over a giant black sponge. The sponge would trap the water. Right? That is pretty much how porous asphalt works. It is the sponge in the scenario, and the water is rainwater.
Then imagine squeezing the water trapped in the sponge into a water filtration system. The filtration system would allow the water to pass through, but it would trap fibers from the sponge and any contaminants in the water.
This is similar to what happens when the storm water permeates through the asphalt. The cleaner water represents the ground water that is allowed to travel away from the porous asphalt.
Porous asphalt can last 20 years or more. Best of all, even after many years of trapping pollutants, this paving does not lose its ability to effectively trap and drain. It can crack or develop potholes, but it is not a common occurrence.
This type of asphalt is ideal for driveways, parking lots, sidewalks and roadways. Cities that have environmental concerns could benefit from considering this as an option to control water pollution.
If you like impervious asphalt based upon its appearance, you will be happy to know that porous asphalt has a similar appearance. Most people observing the two would not know the difference.
Noise Reduction and Safety
Porous asphalt produces less noise than traditional asphalt when it is driven over. Roadways are also made safer when this material is used because there is a reduced chance of skidding, which can contribute to car accidents.
The number of years that this type of asphalt can be expected to last makes it a sensible investment. Some jurisdictions enforce storm water impact fees. It may be possible to get these fees lowered by choosing to go forward with a porous pavement solution.
