What are the benefits of Permeable and Porous Asphalt?

Permeable asphalt paving filters water through the surface to different layers of permeable and impermeable material, before it is directed where it needs to go.

Pervious asphalt, or concrete, soaks up and retains rainwater which gradually works through to the water table and helping to prevent rapid flooding in high risk areas..

Permeable, porous, and previous asphalt has many benefits:

  • Permeable concrete reduces rainwater runoff which helps to prevent toxic water being directed straight into rivers. As many homes and businesses complete day to day activities in their home, having a permeable asphalt that filters the water into the water tables immediately below them instead of directing this through to stormwater channels greatly benefits the local flora and fauna ecosystem
  • The pervious concrete process filters water and reduces the amount of pollutants. The pervious concrete is built of many organic and inorganic layers, such as bedrock, dirt and mesh, that filter the water before it is absorbed below
  • Porous asphalt has proven to reduce the heat temperature on its surfaces of non porous asphalt which reduces local climate temperatures. As Climate Change becomes a bigger and bigger issue, reducing Urban Heat Island Effect forms a big part of the wider strategy to reduce heat. Porous Surfaces are effective at absorbing not just water, but also heat
  • Permeable concrete solutions can save money by reducing the need for waste water management systems or irrigation systems.

A common misconception with permeable asphalt is that they can't handle heavy loads. The exact specifications of load limits will differ from product to product. For example, you would not use the same concrete on your driveway that you would around a truck loading dock. There are permeable asphalt solutions that can handle most urban applications and therefore they are a great choice when choosing your next Asphalt surface.
