​ The incorporation of broken - down scrap tires into asphalt to produce a blend suitable for the construction of surfaces is becoming widespread. The resulting material, asphalt - rubber, has several advantages over customary road building materials. It can be applied in a reduced thickness, and this means that less material has to be mined and transported to the road site. Furthermore, roads constructed with this material require less maintenance than more conventional roads. Another benefit is the abatement of traffic noise, a serious issue in urban areas. Perhaps most importantly, the reduction and possible eventual elimination of waste tires with all their attendant environmental problems may one day become a reality.
