Porous Asphalt Pavement—A Green Paving Solution
What Is Porous Asphalt Pavement?
Porous asphalt pavement is an interesting development in asphalt paving. It’s something that has actually been around since the 1970s but recently has ignited intrigue among developers. What porous asphalt pavement does is better manage stormwater by allowing the water to drain through the pavement surface. The water then flows onto a stone recharge bed and into the soil.
The end result is a storm water management system that is more cost-efficient. Improved water quality and the promotion of infiltration as well as easier long-term asphalt maintenance are other benefits of a well-designed and constructed porous asphalt pavement.
Features and Benefits of Porous Asphalt Pavement
What’s happening with porous asphalt paving is that you are giving the water somewhere to go. This is usually a stone bed that is constructed to precise measurements in order to never allow the water to reach the asphalt. This often removes the need for any kind of detention basin.
Another great benefit of porous asphalt paving is that it lasts. Once the design and installation are done correctly, it’s possible to get up to 20 years out of your parking lot. The fact that it is sustainable through wintery climates is another benefit for cities like Toronto and the surrounding areas. And maybe the best part of porous asphalt paving is that it is a recognized green paving solution. This means that by simply installing porous asphalt pavement, you are helping the environment.
Some of the other benefits include the following:
- Aquifer recharge
- More skid resistant which promotes safety
- Removes pollutants from runoff
- Temperature equalization from storm water runoff
- Less drainage systems needed to meet regulations
Cost of Porous Asphalt Pavement
The initial cost of porous asphalt pavements is more expensive than other sorts of pavements. This is because of the special design and inclusion of features like the underlying stone bed. But, these higher upfront costs are offset by the reduction in the need for other drainage systems. And, when you start to consider that less asphalt paving is needed over the 20-plus-year lifespan of the surface, then the porous asphalt is the better value.
