Porous asphalt is applicable to many uses, including parking lots, driveways, sidewalks, bike paths, playgrounds and tennis courts. With proper maintenance, including regular vacuuming of the surface to prevent clogging by sediment, porous asphalt can have a minimum service life of 20 years.
FIGURE 01 Porous asphalt (top) versus standard asphalt (bottom) after one hour and forty minutes (right) (Houle 2010, 1281). Reduce Runoff According to the USGS, permeable pavement can help "reestablish a more natural hydrologic balance and reduce runoff volume by trapping and slowly releasing precipitation into the ground

Porous asphalt pavement for stormwater management. Traditionally, pavements are designed to allow rainfall and runoff to flow along the pavement surface, draining into adjacent catch basins and/or ditches of roads or parking lots. Porous asphalt pavement, on the other hand, is a type of type porous pavement structure specifically designed to ...
Porous Asphalt is used on highways to remove excess water. Single-Sized Aggregate contains no binder and is commonly known as loose gravel. It can commonly be seen in very low-speed applications such as driveways or pathways. Plastic Grids allow for a porous system and are growing in popularity due to LEED project requirements. These grids ...
Porous Asphalt is a pervious pavement designed to allow stormwater infiltration through the surface into the soil below. The water is naturally absorbed and filtered, and the pollutants are removed. In contrast, regular asphalt pavement is an …
POROUS ASPHALT: CONSIDERATION FOR USE 6. Porous asphalt is a good product for local roads, parking lots and trails. •Parking lots are tough test-low speed turning motions •Resist temptation to mix porous with impermeable pavements in same section •Depth of section can be an issue on high volume roads-consider pervious concrete to avoid existing utilities …
Porous asphalt (Fig. 1) Pervious concrete (Fig. 2) Permeable interlocking concrete pavers (PICP) (Fig.3) Both porous asphalt and pervious concrete are modified versions of the standard material where void space is created within the material to allow water to percolate through the pavement.
Porous asphalt is an environmentally friendly tool for stormwater management. POROUS ASPHALT PAVEMENTS In the natural environment, rainfall sinks into soil, filters through it, and eventually finds its way to streams, ponds, lakes, and underground aquifers. The built environment, by way of contrast, seals the surface. Rainwater and
Both mean a substance that allows liquids or gases to pass through (as opposed to being a solid barrier). These terms are also used synonymously in asphalt. Pervious or permeable pavements have connected spaces that allow water to percolate through the surface. "Porous…
Tech Brief: Porous Asphalt Pavements with Stone Reservoirs, U.S. Federal Highway Administration, 2015 (PDF) (11 pp, 963 K, About PDF) Provides an overview of the benefits, limitations and applications of porous asphalt pavements with stone reservoirs. Considerations for design, construction and maintenance are also discussed.
The porous asphalt course consists of a 2- to 4-in. thick open-graded asphalt layer. The pavement should be a mix containing little sand or dust, with approximately 16 percent voids.
Porous asphalt is really only a slight modification of traditional asphalt. This type of asphalt is even installed in the same way as traditional asphalt. However, the key difference here is that small aggregate materials that would normally be included in traditional asphalt are omitted in porous asphalt.
Porous asphalt pavements are constructed in the form of an underlying, open-graded stone bed that provides drainage for the water. As the water drains through the porous asphalt and into the stone bed, it slowly infiltrates into the soil. However, the stone bed size and depth must be designed so that the water level never rises into the asphalt ...
More and more commercial property owners are investing in porous asphalt for stormwater management. As the name suggests, porous asphalt is filled with pores that allow water to seep through asphalt pavement and enter the soil where it can be filtered of contaminants.. Porous asphalt was designed to mimic the way soil filters stormwater before it flows into waterways, which is better for ...
