Performance Test of Large Scale Embankment made with Bottom Ash and Tire Shred

저회-폐타이어 재생혼합토의 실대형 성토구조물 성능 시험

Recently, a global trend has been established to facilitate the use of waste materials in geotechnical engineering applications. In Korea, where there is the need to save natural resources as these may become scare in the near future and to prevent excessive ground excavation for natural aggregates. The annual production of scrap tire and bottom ash has sharply increased in recent years. Therefore, it will be good waste resource recycling, if we can utilize the above wastes as fill materials in soft ground. In this study, based on the proven feasibility of bottom ash and tire shred-soil mixtures as lightweight fill materials, tire shred-bottom ash mixtures were suggested as a new lightweight fill material to replace the conventional construction material(soil) with bottom ash. Therefore, the main objective of this research is to investigate the feasibility of tire shred-bottom ash mixtures in order to estimate their suitability for the use of lightweight fill materials. So we carried out the performance tests of 2 large scale embankment which were made with tire shred-bottom ash mixture and the conventional fill material(weathered soil) respectively.
