WebThe minimum SBC of soil required for typical residential construction projects ranges from 100 kN/m² to 200 kN/m². However, for high-rise buildings, bridges, or other structures that experience heavy loads, the required SBC can be much higher, often exceeding 500 kN/m². WebFigure 7shows compaction curves for the samples. It explains the maximum compaction of the soil at optimum water content and dry density. The compaction result showed that the soil optimum moisture content (OMC) ranges between 13.45 and 17.05%, while the maximum dry density (MDD) ranges from 1.86 to 2.22 g/cm 3 (Table 3).
