Geocomposite materials consisting of lightly cemented mixtures of expanded polystyrene beads (EPS) and backfill soils are commonly used as fillers and for the construction of light weight embankments. The constant normal stress (CNS) and constant volume (CV) direct shear parameters as well as the relationship between gradation properties of four residual granular backfill soils and direct shear parameters of lightly cemented mixture of EPS and backfill soils was evaluated. The maximum density an...

In this study we investigated the possibilities of using recyclable fine and coarse grain waste obtained by grinding Polyethylene Terephthalate (PET) containers, as light filling materials for different applications (clay dams, highway embankments, and backfills behind retaining structures. Various geotechnical tests were performed on clayey soil and soil-PET mixtures using recycled fine and coarse granules of Polyethylene Terephthalate bottles. The results indicated that the use of the recyc...
