“Green Pavement” might sound like an oxymoron at first, but this new concept in environmentally-friendly construction is gaining traction.
What comes to mind when you think of pavement? Probably images of hundreds of thousands of miles of asphalt and concrete pavement. How can pavement become something earth-friendly?
Green pavement is a water-permeable paving material that allows rainwater to percolate through the pavement and seep into the soil instead of running off into sewers or causing floods. Green pavement has the potential to add millions of square miles, the soil beneath our streets and other paved surfaces, back into the natural water-cycle equation. Green pavement can also be made from materials that are themselves recycled.
Currently, green pavement does have some drawbacks. It is more expensive to install than traditional pavement and requires special maintenance to prevent clogging. However, with more research and development, these obstacles might be overcome.
