Design and Contruction of a Porous Asphalt Stormwater BMP ...
What is a Porous Asphalt BMP? A Porous Asphalt BMP is a BMP where the surface is composed of an asphalt open-graded friction course (OGFC) manufactured with larger-diameter aggregates to achieve an effective porosity of approximately 19% (by UNHSC Spec.). This OGFC is underlain with a subbase composed of larger-diameter aggregates.

ISSN : 2454-9150 POROUS ASPHALT PAVEMENT
The porous asphalt pavement which can be used for parking lot or low-trafficked roads/streets works like this. The top 75 mm asphalt layer is specially designed to make it porous. Rainwater goes through it rapidly without any ponding. The water is then stored in an underlying open-graded stone bed, which is about 225 mm thick. From there, water ...
State-of-the-art of porous asphalt pavement: Experience ...
Porous asphalt (PA) is a distinct mixture type that deliberately designed with stone-on-stone contact of the coarse aggregate fraction and high percentage of interconnected air voids to provide water drainage and adequate resistance to both raveling and permanent deformation. During the past decades, PA has attracted much attention in the ...

Permeable asphalt pavement or porous friction course is commonly knows as porous asphalt. The porous pavement used in japanes and europe. The pavement consists in a porous overlay allowing rainwater to flow down to the botton the overlay and then to drain on the edges of the pavement. Quality of porous asphalt was developed to drain pavement
The Study of Porous Asphalt Pavement with Emphasis in Road ...
Porous asphalt pavements are typically built over an uncompacted subgrade to maximize infiltration through the soil. The last layer consists of one or more layers of porous asphalt mixes with interconnected voids that allow water to flow through the pavement into the stone reservoir. These porous asphalt layers consist of asphalt ...
