The following section provides design guidelines for porous asphalt, pervious concrete, a permeable interlocking concrete pavement, and a plastic grid system. Each product has specific design requirements and each site has unique characteristics and development requirements.
Porous asphalt pavement is then placed over the top of these basins. These pavements are designed to let the water flow through them and into the detention basin. Porous asphalt pavement is commonly known as open graded asphalt concrete (OGAC), open graded friction course (OGFC), and permeable asphalt.

8.2. Permeable Pavement Construction Sequence. The following is a typical construction sequence to properly install permeable pavement, which may need to be modified to depending on whether Porous Asphalt (PA), Pervious Concrete (PC) or Interlocking Paver (IP) designs are employed. Step 1.
Permeable interlocking concrete pavement (PICP) is a durable cost-effective solution for compliance to national, state/provincial and municipal stormwater regulations. PICP can reduce runoff and pollutants from walkways, patios, driveways, parking lots, alleys, parking lanes, and low volume streets.
Porous asphalt pavement is a paved surface and subbase comprised of aggregates and asphalt binder, designed, placed and compacted in a manner resulting in a highly permeable asphalt concrete surface (approximately 17% voids).
Permeable pavements are alternative paving surfaces that allow stormwater runoff to filter through voids in the pavement surface into an underlying stone reservoir, where it is …

Pervious Concrete Specification. Download Pervious Concrete Spec (PDF) Since we pioneered efforts to create and publish a Pervious Concrete Specification on the internet in the 1990s, the use of Pervious Concrete Pavement, (also known as "no fines concrete" "zero slump concrete" and "porous concrete pavement") has continued to gain acceptance.
Permeable asphalt can be integrated into drainage schemes or be utilised as a complete system to help create a Sustainable Drainage System (SuDS). It is the inherent infiltration, attenuation and pollutant retaining properties of the solution that enable it to contribute to …

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
Introduction Permeable paving is a relatively recent introduction to the British and Irish paving markets, but one that is set to dominate the trade in the coming years.
Asphalt, Site Concrete, and Pervious Concrete Maintenance Guidelines General These guidelines have been developed to help facilities managers, project managers, consultants and contractors maintain and extend the service life of asphalt, site concrete, and pervious concrete.
The following table describes general material specifications for the components installed beneath the permeable pavement. Note that the size of stone materials used in the reservoir and filter layers differ depending whether the system is pervious concrete, porous asphalt or permeable interlocking concrete pavement.

Permeable pavers are composed of a layer of concrete or fired clay brick. The pavers are separated by joints filled with crushed aggregate. Permeable pavers are different from pervious and porous pavers in that rainwater passes around the paver opposed to through it.Permeable is a term used to describe paving methods for roads, parking lots, and walkways.
