14.The incorporation of broken-down scarp tires into asphalt to produce a blend suitable for construction of road surfaces is becoming widespread. The resulting material, asphalt-rubber, has several advantages over customary roadbuilding materials. It can be applied in a reduced thickness, and this means

more conventional roads. Another benefit is the abatement of traffic noise, a

serious issue in urban areas. Perhaps most important, the reduction and possible eventual elimination of waste tires with all their attendant environmental problems may one day become a reality.
