In United States, Yellowstone is known as an eco-sensitive environment and therefore very high standards are peculiar to the area, especially as regards to environmental innovation. As old roads in Yellowstone require ever more maintenance, the park’s authorities unanimously opted for new environment-friendly porous pavement which is partly produced from recycled tires.

The park has the world’s largest system of geysers and thermal streams. Improvements to the roads would help avoid or significantly reduce erosion in numerous areas of the park.

As regards to the pavement surface, it was decided to create a porous structure, durable and flexible enough to allow water to go through the road surface as if there were no surface at all. According to Yellowstone, these measures would enable a more natural water pattern which, in turn, would help replenish the geyser basin.

The road will be partly composed of crumb rubber and stone. The open-pore structure would enable to get rid of water from the road surface. Reportedly, the structure will be capable of evacuating up to 4,000 cubic inches per hour.

Lynn Chan, a landscape architect at Yellowstone National Park, pinpoints the importance of restoring the park’s pavements, roads and walkways using such materials that will protect the park’s sensitive environment and simultaneously allow people to visit the park and appreciate its amazing nature.
