Permeable pavement is also known as pervious or porous pavement. It is made of pervious concrete which allows water to permeate through it and help return water to underground aquifers. Not only this, permeable pavement also stops suspended solids and other pollutants from entering into the water stream.
Where are permeable concrete used?
Permeable concrete can be used to construct pavements, residential roads, sidewalks, parking lots, well linings, swimming pool decks, patios and several others.
What are permeable pavements made of?
Permeable pavements are constructed from permeable concrete which can be of the following types:
- Porous asphalt
- Permeable interlocking concrete pavers (individual units with gaps filled with grass or small stones)
- Resin bound paving (mixture of clear resin and aggregate)
- Bound recycled glass porous pavement (mixture of post-consumer glass with resins and binding agents).
What are various benefits of permeable pavements?
Permeable pavements are green options in construction. They have several benefits like those mentioned below.
- Permeable pavements help recharge groundwater by reducing run-offs.
- They trap suspended solids and other pollutants and prevent them from entering the water stream. For example, TSS and TP loads.
- They also help reduce surface temperatures.
- Permeable pavements are good options in urban areas with high population density and with less number of BMPs like ponds, swales or bio-retention systems.
- These eliminate the need to construct retention basins, curbs, gutters and other water collection areas.
- They require less de-icing products than traditional pavement types.
- Permeable pavements require low installation costs, making them a budget-friendly and eco-friendly option to have in cities.
- Their longevity is no less than conventional concrete pavements, amounting anywhere from 20 to 40 years, depending on installation procedure.
