Porous asphalt is an environmentally friendly tool for stormwater management. POROUS ASPHALT PAVEMENTS In the natural environment, rainfall sinks into soil, filters through it, and eventually finds its way to streams, ponds, lakes, and underground aquifers. The built environment, by way of contrast, seals the surface. Rainwater and
Permeable Pavement Installation. Permeable Pavement will be reimbursed at a rate of up to $10.00 per square foot with a maximum payment of $10,000.00. 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 temporarily stored ...
Pervious pavements provide a valuable stormwater management benefit to help offset the costs of constructing and maintaining traditional Stormwater Control Measures, like retention basins. The cost to install pervious pavement is approximately $7 per square foot, which is slightly more expensive than traditional pavement.

Figure 1: Routine and adequate maintenance has allowed the porous asphalt parking lot at the Morris Arboretum to still be effective 20 years after installation. Planted areas adjacent to porous pavement should be well maintained to prevent soil washout onto the pavement. If any washout does occur it should be cleaned off the
Pervious concrete, porous asphalt, permeable pavers, or other forms of pervious or porous paving material intended to allow passage of water through the pavement section. It often includes an aggregate base that provides structural support and acts as a stormwater reservoir.
Porous Asphalt PURPOSE: Porous asphalt used in place of traditi onal impervious paving materials decreases the total amount of runoff leaving a site, promotes infiltration of runoff into the ground, reduces the amount of pollutants carried to a storm drain or waterway, and …
Permeable paving techniques include porous asphalt, pervious concrete, paving stones, and manufactured "grass pavers" made of concrete or plastic. Permeable paving may be used for walkways, patios, plazas, driveways, parking stalls, and overflow parking areas. A parking lot with conventional asphalt aisles and paving stone parking stalls.
Porous asphalt costs more to install than standard asphalt because it requires a stone recharge bed underneath the surface layer. But the cost of porous asphalt must be compared with alternatives before determining the final cost. For example, if you were planning on needing a detention basin to handle stormwater runoff, the cost of porous ...
The installation process for permeable pavers is also quicker and more cost-effective than with asphalt or concrete. Permeable pavers require almost no upkeep or maintenance and will serve you better than either traditional or porous asphalt or concrete would, and for much longer.
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.
Pervious pavement effectively treats, detains, and infiltrates stormwater runoff where landscape-based strategies are restricted or less desired. Pervious pavements have multiple applications, including sidewalks, street furniture zones, and entire roadways (or just their parking lane or gutter strip portions).
Pervious concrete has many wonderful properties, but without an experienced contractor and ready-mix supplier, a failed installation is possible. Pervious concrete is difficult to place and finish properly. The right mix and proper compaction and curing are critical to success.
The porous asphalt course consists of a 2- to 4-in. thick open-graded asphalt layer. The pavement should be a mix containing little sand or dust, with approximately 16 percent voids.
A major part of the installation is the cost of the paving material itself. Some rough estimates per square foot of paved area are as follows [ 7 ]: Gravel and other natural aggregates: $0.50 – $2.00. Asphalt and Permeable Asphalt: $1- $5. Concrete and Permeable Concrete: $3 – $10. Concrete Interlocking Pavers: $10 – $50.
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.
Porous Asphalt: The production and placement of porous asphalt is the same as in the conventiona l asphalt concrete; it differs in that fine (small) aggregates are omitted from the asphalt mixture. The remaining large,single-sized aggregate particles leave open voids that give the material its …
Hydraulic conductivity — the system is permeable and can eliminate surface ponding (see sections 10 and 15).

The BBA has awarded this Certificate to the company named above for the system described herein.
A pervious pavement bed consists of a pervious surface course underlain by a stone bed of uniformly graded and clean-washed coarse aggregate, 1-1/2 to 2-1/2 inches in size, with a void space of at least 40%. The pervious pavement may consist of pervious asphalt, pervious concrete, or pervious pavement units. Stormwater drains through the

Pervious materials will cost more than asphalt surfaces with some systems costing as much as 40% more. If used in areas with underground utilities needing repair, pervious paving materials can easily be removed from only the repair area. Pavement replacement is simplified and expensive measures such as asphalt cutting are eliminated.
Porous Asphalt is a pervious pavement designed to allow stormwater infiltration through the surface into the soil below. The water is naturally absorbed and filtered, and the pollutants are removed. In contrast, regular asphalt pavement is an impervious surface that sheds and repels rainfall and surface pollutants.
A variety of permeable pavement materials are available, such as interlocking pavers, porous asphalt, pervious concrete, and manufactured grass pavers. Interlocking pavers consist of precast blocks (primarily brick or concrete) that are aligned in such a way that water is able to pass between the blocks into the soil below.
B. The work of this Section includes subgrade preparation, installation of the underlying porous media beds, and porous asphalt mix (mix) design, production, and installation. Porous media beds refer to the material layers underlying the porous asphalt pavement. Porous asphalt pavement
With the proper design and installation, porous asphalt structures can offer cost-effective, attractive parking lots with a long life span while also providing storm water management systems that promote infiltration improve water quality. Key Words: Porous asphalt pavement, storm water runoff,
The installation at the Ramsey Washington Metro Watershed District offices in Little Canada, MN installed pervious asphalt in their parking lot. Pervious concrete - Pervious concrete is a mixture of Portland cement, fly ash, washed gravel, and water. Unlike conventional concrete, pervious concrete usually contains a void content of 15 to 25 ...
Pervious, porous, and permeable pavers are different paving systems that reduce stormwater runoff. Each paver type has a different installation process and application, depending on the soil and site conditions. Pervious concrete drains faster than porous asphalt or permeable pavers.
With proper design and installation, porous asphalt pavements can provide a cost-effective solution for stormwater management in an environmentally friendly way. As a result, they are recognized as a best practice by the U.S. Environmental Protection Agency (EPA) and many state agencies

The first step in the asphalt installation process is to remove the existing surface, whether it is asphalt, concrete or pavers. Demolition and removal is completed using heavy machinery, including small bobcats and forklifts and when necessary, front loaders and large dump trucks.
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.
