The difference between permeable and porous asphalt

22/01/2018  The difference between permeable and porous asphalt. Permeable or pervious asphalt has connected spaces that allow water to pass or percolate through the surface. Porous asphalt has holes that allow water to penetrate but since the spaces are not interconnected, it doesn’t move underneath to the underground water table.

How do Permeable Pavement Systems Compare?

Porous Asphalt: 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 beyond 20 years. Application ...

Porous Asphalt Fact Sheet - dauphincd

Porous asphalt consists of standard bituminous asphalt in which the fines have been screened and reduced, creating void space to make it highly permeable to water. The void space of porous asphalt is approximately 16%, as opposed to two to three percent for conventional asphalt. Porous asphalt itself provides for some pretreatment of runoff. The crushed aggregate filter layer aids with ...
