Pervious concrete pavement is a pavement type that allows rainwater and other sources of water to percolate into the base layer below the concrete. Thus allowing the base material to absorb and control the flow rate of the water as it moves off site.
Pervious concrete pavement is a unique and effective means to address important environmental issues and support green, sustainable growth. By capturing stormwater and allowing it to seep into the ground, porous concrete is instrumental in recharging groundwater, reducing stormwater runoff, and meeting U.S. Environmental Protection Agency (EPA ...

GEOPAVE® Rigid Porous Pavement Systems Compared to Rolled Products. Optimal Load Distribution. The GEOPAVE system's shared wall system, strong connection clips and load-spreading mesh bottom (snow ...
Porous asphalt pavements are being used to reduce or eliminate storm water runoff from parking lots and other such facilities. A porous asphalt pavement is constructed over a stone filled reservoir to collect and store storm water and to allow it to infiltrate into the soil between rainfalls (Figure 1). Where low soil permeability is no
Porous asphalt used in place of traditional impervious paving materials decreases the total amount of runoff leaving a site. It promotes infiltration of runoff into the ground, reduces the amount of pollutants carried to a storm drain or waterway, and aids with reducing peak runoff velocity and volume.
As shown in Exhibit 1, a typical porous asphalt pavement consists of a top porous asphalt course, a filter course, a reservoir course (designed for runoff detention and frost penetration), and existing soil or subbase material. The top porous asphalt course is an open-graded asphalt concrete surface course approximately 2-4 inches thick.
How to Maintain Your Porous Pavement Page 1 of 2 2013 l Montgomery County, ... Porous asphalt . 2. Pervious concrete 3. Permeable interlocking pavers . Although porous pavement can replace many traditional asphalt and concrete surfaces, in . Montgomery County it is most commonly found in
Aug 12, 2013· Black is the new "Green"! Porous asphalt is pervious asphalt that allows water to penetrate into an underground storm water management facility. This will allow the water to perk into the ground ...
In most applications, porous asphalt is a cheaper option than pervious concrete or pavers. Although initial costs are typically higher than standard asphalt, it can be a cost-effective solution if it eliminates the need for stormwater infrastructure. According to the National Asphalt Pavement Association, porous asphalt can have a life span ...
A typical porous pavement has an open-graded surface over an underlying stone recharge bed. The water drains through the porous asphalt and into the stone bed, then, slowly, infiltrates into the soil. If contaminants were on the surface at the time of the storm, they …
May 21, 2014· The permeability of test sections was comparatively measured for porous asphalt, pervious concrete, and permeable interlocking concrete paver pavements using both the American Society for Testing and Materials (ASTM) C1701 and the National Center for Asphalt Technology (NCAT) methods (using constant-head and falling-head methods, respectively; see Chapter 5).
Topmix Permeable is a fast draining concrete pavement solution that rapidly directs stormwater off streets, parking surfaces, driveways and walkways. This minimises the cost and long-term maintenance for local authorities and developers of stormwater management.
Porous Pave is a pour-in-place permeable paving material that is highly porous, flexible and resilient. An eco-friendly green building product made in the U.S.A. with recycled rubber, Porous Pave offers superior permeability, exceptional versatility, and demonstrated durability.
Alternatives to traditional pavement on our paved surfaces can help reduce runoff by infiltrating rain water and melting snow. These alternative materials which include pervious asphalt, pervious concrete, interlocking pavers, and plastic grid pavers, allow rain and snowmelt to seep through the surface down to underlying layers of soil and gravel.
This prevents sediment from clogging the pavement. The University of Central Florida (.pdf) conducted independent tests of FILTERPAVE®, and pervious concrete, and porous asphalt. The tests concluded that if clogged, FILTERPAVE® can be easily rejuvenated while porous asphalt and pervious concrete remain mostly clogged..
May 02, 2017· Porous asphalt pavement can be a valuable tool for business developers, municipalities and even homeowners who are interested in storm water management. Porous asphalt pavement is an environmentally-conscious and sustainable paving solution …
Whether it is pervious concrete, porous asphalt, paving stones or concrete or plastic-based pavers, all these permeable paving systems allow stormwater to percolate and infiltrate the surface areas, bypassing the traditionally impervious materials to the soil below. The goal is to control stormwater at the source, reduce runoff and improve ...
Jan 25, 2017· Permeable pavement is a pavement type with a porous surface that is composed of concrete, open pore pavers or asphalt with an underlying stone reservoir. Also considered as green pavement, it allows water to run through it rather than accumulate on it or run off of it. The precipitation and water get stored in the
A permeable asphalt system provides an effective solution to mitigate the increase in impermeable surfaces associated with new developments and urbanisation. Permeable asphalt can be integrated into drainage schemes or be utilised as a complete system to help create a …
Permeable pavement (also known as pervious or porous concrete) is a specific type of pavement with a high porosity that allows rainwater to pass through it into the ground below. Through this movement, pervious concrete mimics the natural process that occurs on the ground's surface, consequently ...
There are other environmental benefits to this type of pavement. Because of the open structure of the pavement, porous asphalt offers a "cooler" pavement choice. By replenishing water tables and aquifers rather than forcing rainfall into storm sewers, porous asphalt also helps to …
Whether it is pervious concrete, porous asphalt, paving stones or concrete or plastic-based pavers, all these permeable paving systems allow stormwater to percolate and infiltrate the surface areas, bypassing the traditionally impervious materials to the soil below. The goal is to control stormwater at the source, reduce runoff and improve ...
The same is not true of porous asphalt. Cost: Both pervious concrete and porous asphalt cost roughly 20 percent more to install than their traditional counterparts, with concrete costing slightly more to install than asphalt. One reason for the higher installation cost of pervious concrete is that the concrete is laid thicker.
Figure 1: Typical porous asphalt pavement with stone reservoir cross section . 2 | Porous Asphalt Pavements with Stone Reservoirs FHWA-HIF-15-009 . Unlike conventional pavements, porous asphalt pavements are typically built over an uncompacted subgrade to maximize infiltration through the soil.
Oct 28, 2016· Porous asphalt is better suited for low vehicle weight roads and parking lots. Basically, asphalt or pavers would normally be used, their permeable counterparts can be used. Installation. Porous asphalt can be installed in the same manner as traditional asphalt. It does not require any special paving equipment or skills.
This prevents sediment from clogging the pavement. The University of Central Florida (.pdf) conducted independent tests of FilterPave, pervious concrete, and porous asphalt. The tests concluded that if clogged, FilterPave can be easily rejuvenated while porous asphalt and pervious concrete …
in other sources, terms often used are: pervious pavers, pervious concrete, porous asphalt, resin-bound paving, open-jointed blocks or cells and porous turf. Permeable pavement is a method of paving that allows stormwater to seep into the ground as it falls rather than running off into storm drains, waterways and eventually the Chesapeake Bay.
Phase I Porous: 40,300 sf of asphalt, 14,300 sf concrete, and 8300 sf of pavers Phase II Porous: two mix designs of porous asp (both 20,700 sf) and 12,100 sf of porous concre On-going quality and quantity monitoring by Kinnetic Labs Grant from the State of CaliforniCalifornia Water Resoua Water Resour Control Board (and County matching funds)
While slightly coarser than standard asphalt, porous asphalt pavements are attractive and acceptable. Most people parking on a porous asphalt parking lot will not notice (or believe) that it is porous. The surface of a porous asphalt pavement is smooth enough to meet requirements of the Americans with Disabilities Act (ADA).
