In geotechnical
engineering applications, different geosynthetics are used to ensure the
usability of the structure throughout its service life, increase the expected
performance and reduce the cost. One of the geosynthetics with different
properties that have emerged with current technological developments is the
expanded polystyrene (EPS) material, which has a low density and high
compressibility. There are usage areas such as road underfill, buried pipe
systems, retaining walls, and slope stability. When the usage areas are taken
into consideration, it is seen that the EPS material interacts with the soil.
It is essential to determine the EPS-soil interface interaction by considering
different loading conditions and soil properties in designing these structures.
This study determined the interface shear strength parameters of three poorly
graded granular soils and two different densities of EPS material by
large-scale direct shear box tests. Thus; d, ca, and d/f values were
determined for applications with EPS-soil interaction.
