Expanded polystyrene wastes are accumulated in huge amounts. The lack of reclamation sites has accelerated the need to find methods of reuse these wastes as construction materials. It is very serious issue to reuse of low quality construction surplus soils because the law will be prepared that 90% surplus soils should be reused at the site in the near future. In this paper, a new attempt was made to investigate the efficiency of the expanded polystyrene wastes with surplus soils as lightweight fill materials behind retaining wall. For this purposes the physical characteristics of the expanded polystyrenes and surplus soils were examined respectively. Furthermore, retaining wall model tests were conducted by alternately sandwiching the polystyrene between the surplus soil layers. The stability and deformation behavior of the fill were evaluated.
