2011-9-30 With proper design and installation, porous asphalt can provide pavements with a lifespan of more than 20 years and provide storm-water management systems that promote infiltration, improve water quality, and often eliminate the need for a detention basin. The performance of porous asphalt pavements is similar to that of other asphalt pavements.

2015-1-22 The design for application of porous asphalt consists of at least four layers: a twoto four-inch layer of asphalt, a one to two-inch filter layer of half-inch crushedaggregate, a 12-inch minimum reservoir layer of one to three-inch aggregate,and a layer of geotextile material. Porous asphalt consists of standard bituminousasphalt in which the fines have been screened and reduced, creating void space tomake it highly permeable to water. The void space of porous asphalt isapproximately16%, as opposed to two to three percent for conventional asphalt. Porous asphaltitself

2019-9-5 Porous concrete or asphalt surfaces are made up of a coarse aggregate that is coated in mortar or cement paste. This creates a structure in which there are countless pathways for water to trickle through the surface and down into a collection area or directly into the soil. In theory, this is a great idea.

2015-6-16 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.

If adding fiber, including basalt, cellulose, and blends including aramid, Baird suggests adding 0.3 to 0.6 percent by weight during the dry mix stage and increasing dry mix time by a minimum of 20 seconds. Temperature, Baird said, is the most influential metric in the production and installation of porous asphalt.
