Physical properties and compression index of embankment soil as construction material

Abstract Soil’s physical properties are characterized by its shape, size, color, and odor. The compression index, a key parameter of soil compressibility, is used to determine the extent of consolidation settlement. This study serves as preliminary research into alternative embankment materials for construction. The embankment soil samples were collected from ten locations in Aceh Besar district. The research aims to assess the quality of embankment soils and predict potential land subsidence, contributing to sustainable development in Aceh Province. This is particularly important because the fill soils in this area are crucial as the primary source for various development projects in Aceh Besar and Banda Aceh. The results indicate that clayey soils require careful consideration as construction materials due to their higher potential for subsidence. Conversely, silty sand or clayey soils are more suitable for construction because of their lower compressibility.
