When paving a driveway or parking lot, you may wonder if all asphalt is the same. The answer to that question is “no.” While pervious and permeable asphalts permit gases or liquids to pass through surfaces, porous asphalts are slightly different.
Porous Paving Services
According to paving contractors in Annapolis, MD, porous asphalt features spaces or holes in the surface. However, these spaces are not connected as they are in pervious or permeable asphalt pavements. While the water percolates through pervious asphalt, which leads it down to the water table, it does not do so when porous asphalt is used. Instead, the water does get through the surface but has nowhere to go.
However, that being said, paving contractors acknowledge that these distinctions are usually not made in the paving industry. Nevertheless, if you are involved in stormwater management, the terms are significant. If you choose impervious asphalt, the pavement will force the water to run into drain systems and waterways too quickly, which could lead to flooding.
Do You Manage the Stormwater Runoff on Your Property?
If you use an impervious pavement, you also have to take another measure to catch the stormwater runoff. In this case, you may want to speak to paving contractors about a permeable pavement, which can reduce the overall environmental impact. While the terms permeable, pervious, or porous might sound similar, you still need to verify these types of pavements.
