| Popis: | Lateritic soils derived from coastal plain sands around Ogua, Niger Delta in Nigeria, were investigated with a view to elucidate their geotechnical characteristics, which may have influence on their engineering applications. The geotechnical properties of these soils (their compaction parameters, permeability, consolidation and shear strength) as well as index properties were investigated in the laboratory. Grain size analysis indicates that the soils are well graded with amount of fines ranging from 60% to 65%. The gravel content of the soils ranges between 2% and 3% while the linear shrinkage ranges were between 7% and 10%. The soils classify as CL soils in the USCS and in group A-7 of the AASTHO classification. The engineering properties of the soils are affected by compaction energy. However, statistical analysis shows that compaction energy has a significant effect only on the permeability coefficient. The statistical test also shows that modification such as soaking and curing have a significant eff... |
