Porous Asphalt - asphaltpavement

Porous asphalt is an environmentally friendly tool for stormwater management. In the natural environment, rainfall sinks into soil, filters through it, and eventually finds its way to streams, ponds, lakes, and underground aquifers. This is different from the way the built environment seals the surface.

Porous Asphalt “When it pours, it’s porous.” Porous asphalt pavements offer developers and planners a new tool in their toolbox for managing storm water. These pavements, used mostly for parking lots, allow water to drain through the pavement surface into a stone …

Porous Asphalt Pavements

Porous asphalt pavement, on the other hand, is a type of type porous pavement structure specifically designed to allow rainfall and runoff to flow into and through the pavement structure. Porous pavement offers the potential to collect and/or slow the rate of run-off from other impervious surfaces.

POROUS ASPHALT PAVEMENTS

porous pavement designers. Many porous pavements have been constructed since the late 1970s. Cahill Associates has been involved in the design and construction of more than 200 porous asphalt pavements since the 1980s and have reported no failures of pavements for which proper design and construc-tion practices were followed.

Porous pavements can be constructed using either asphalt or concrete materials or in some cases, placed pavers. This study concentrates on porous pavements constructed using asphalt. The use of porous asphalt pavements has become more common in recent years as the requirements for stormwater runoff have become more stringent.

The Differences of Pervious, Permeable, and Porous Asphalt

Take asphalt -- if you’re just learning about it, terminology can be a barrier. Those in the industry don’t think twice about terms like “hot-mix” or “sealcoating,” but for the layman, these can be confusing. Pervious and Permeable and Porous, Oh My! Some terms that often get mixed up are pervious, permeable, and porous. These sound similar, like they all mean the same thing.
