More than sixty cities around the US, including New York and Washington DC, have installed some rubber sidewalks made from recycled tires. The material is manufactured by Rubbersidewalks Inc
. From the Associated Press:
Since 2001, Rubbersidewalks has been grinding thousands of old tires into crumbs, adding chemical binders and baking the material into sidewalk sections that weigh less than 11 pounds a square foot, or a quarter of the weight of concrete. The panels are available in two shades of gray and a terra cotta orange.
Many of the squares have been installed in areas where damage from tree roots, weather and snow removal have required sidewalk replacement or major repairs every three years, said Lindsay Smith, founder and president of Rubbersidewalks. Rubber sidewalks are expected to last at least seven years, Smith said...
