Yellowstone National Park is teaming up with Michelin to produce a sustainable road made from recycled tires. Every year, more than three million people drive over Yellowstone's roads. These roads not only require significant upkeep, but they also wear out the tires on the park's well-worn vehicles.
Yellowstone has devised a way to solve both of these issues by putting worn-out tires to good use. Yellowstone has called on Michelin to shred the old tires from park vehicles and turn them into a porous asphalt. The result of the shredding process is a material called 'Flexi-Pave,' which is far superior to asphalt because it is durable and porous to rainwater. The park can ultimately use the Flexi-Pave material to repave its damaged roads. As a result, the recycled tires are turned into a sustainable road.
The project demonstrates one of the unique ways that National Parks are trying to preserve their resources with as little impact on the environment as possible.
