Rubber Sidewalks

Recycled tires are being used as a more flexible substitute to concrete for sidewalks. From the Christian Science Monitor article:

Some 130,000 square feet of rubberized sidewalks grace about 60 North American cities, giving local governments an alternative to concrete and its attendant pitfalls, such as rising prices, exorbitant trip-and-fall lawsuits, and a trail of chopped-down urban trees.

Unlike concrete, which is poured and set on location, the prefab rubber squares arrive from its California factory and are cut to fit. Installers usually place Rubbersidewalks pavers over a bed of crushed granite and connect the pavers using interlocking dowels. The result: a sidewalk with a two-inch-deep footprint - far shallower than its concrete cousins. To repair a rubber sidewalk, workers simply unlock the dowels and remove the individual paver.

Each square foot of rubberized sidewalk contains almost one discarded tire. Americans generate about 290 million waste tires a year, according to the Rubber Manufacturers Association in Washington - many of which languish in junk yards or are burned.
