FORTA-FI® Fills in the Gaps- Porous Asphalt

Some questions that arise when someone is considering to use porous asphalt revolve around the durability and resistance against things such as raveling, rutting, and cracking. Yes, the storm water drainage is a plus, but how can it be durable with the large percentage of air voids? This question explains the reputation surrounding porous asphalt of being less durable compared to traditional asphalt. If the porous asphalt has large air voids, one can assume that it would be more susceptible to damage.

How can porous asphalt still retain its permeability and resist rutting and raveling? —Use FORTA-FI® reinforcing fibers!




Wee Burn Country Club in Darien, CT., is the home of a 1-acre porous asphalt pavement parking lot reinforced with FORTA-FI®. By adding FORTA-FI® to the mix, the porous asphalt has a higher resistance to raveling, rutting,  and cracking. How does it work? FORTA-FI® helps to bridge the gap between the aggregates created by the large air voids but does not inhibit the storm water from draining through the surface. The fibers surround the aggregates forming a strong hold but are small enough to retain the permeability of the pavement. By using porous asphalt, issues caused by rainwater can be eliminated, alleviating the strain put on existing storm water management systems.
