The existence of thick compressible clayey silt deposits along the Sava River provides major obstacle for design and construction of highway embankments in this region. To understand the consolidation and permeability characteristics of this alluvial layer and then to develop reliable soil parameters for earthwork design and construction, a comprehensive soil testing program was carried out. The program consisted of both in situ tests [e.g., standard penetration test borings, piezocone penetration test (CPT) soundings, Marchetti flat dilatometer test soundings, Lefranc test and CPT pore pressure dissipation tests] and laboratory tests (e.g., soil index tests, consolidation tests). The field and the laboratory test results showed that the clayey silt deposit was highly overconsolidated at the top and lightly overconsolidated at greater depths. The findings obtained from this study will be beneficial for future design and construction of Embankments along the Sava River. |
