Life Cycle Assessment of Utilization of Shredded Tire for Sustainable Road Embankment
摘要
This paper provides a life cycle assessment on the use of scrap tire used in subgrade for road embankment construction. The objective of this study is to compare energy consumption and greenhouse gas emission for two methods of constructing the fill embankment, a traditional method involving the filling with sand/soil materials and an alternative method utilizing the shredded tires. The replacement of shredded tires to soil by volume ranged from 10 to 50%. The life cycle assessment of scrapped tired is assessed. The result shows that the use of used car tire in embankment for soil is unlikely to offer environmental benefits due to the use of energy intensive tire recycling processes.
