There is a new recovery method that discarded tires are used with soil as reinforced materials in slope, which has many merits, has not environment pollution and cost saving.
Discarded tires used as reinforced materials have distinctive mechanical properties, such as high tensile strength, good anti-friction, fine flexility and durability etc[1-4].
Discarded tires reinforced in slope and retaining wall can not only reduce environment pollution resulted from discarded tires, but also increase source of reinforced soil materials.
The significant advantage of the propose scrap tire reinforced earth system would be the reduced cost of materials and construction.
