When considering porous asphalt paving it is important to look at all of the factors including the cost and the environmental benefits when compared with other options. Porous asphalt paving is touted as the way to handle damaging storm water through environmentally friendly means while also providing a cost effective alternative.for more information, read this post here.
Unlike other pavements, this option diverts rain water to drain through the asphalt surface and filters it with a stone recharge bed where toxins from the surface can be removed and then the water is absorbed into the soil below the pavement where it can return to local reservoirs.
Long Term Sustainability
One of the main benefits of porous asphalt paving is its longevity. This type of asphalt pavement can last up to 20 years or more before showing signs of deterioration which cuts down on asphalt repair and new driveway paving. Porous asphalt allows for rainwater to flow through the pavement instead of leaving standing water on the surface which can cause faster wear and breakdown of the medium and offers an innovative way to circumnavigate standing water straight through the pavement surface, down through a stone filtration system and back into the soil below the pavement to be reabsorbed and pollutant free. The Walden Pond State Reservation in Massachusetts had their parking lot paved in 1977 and it has held up through today with no repaving.read more information at http://www.columbiatribune.com/business/saturday_business/filterpave-aims-to-expand-use-of-its-porous-pavement/article_fde24177-1539-5dfe-9b7c-73a6c124394b.html#image_1.
One of the main benefits of porous asphalt paving is that it is an environmentally friendly paving substance. It offers clear benefits through its filtration system that is shown to remove heavy amounts of solids, oil, metals, and grease, all of which would otherwise end up leaching down into local soil. Furthermore, it is also more temperate, offering a cooler option to traditional pavement. Many pavements can put off mass amounts of heat due to their impervious nature, however, the porous asphalt paving has a built in ventilation system through the same holes that allow it to filter water.
When looking at porous asphalt paving it is important to consider the multitude of purposes:
• Parking Lots
From this list it can be seen that porous asphalt has a use for nearly everyone. Adding to its value is the fact that it can be used for a wide array of projects ranging from the professional to the do-it-yourself home improver.
Not only is porous asphalt environmentally friendly it is also cost effective. While initial analysis may tend to show that permeable pavements tend to be two to three times as expensive as non-permeable alternatives, it is important to factor in the cost of onsite storm water. On site storm water can become very expensive and porous asphalt paving significantly cuts down those costs through its ability to redirect the water. Unfortunately these savings are not usually factored into the cost but should be considered when looking at cost analysis.
Through much research it has been found that porous asphalt paving has been proven to be a cost effective, environmentally friendly choice that will hold up long after other paving substances have begun to break down from wear and tear.
