The results of compaction test in the laboratory using the standard proctor method for the Ayer Hitam residual soil are tabulated in Table Q1(c). After compaction of the soil in the laboratory, the field density tests using the sand cone replacement method were performed. Assume the specific gravity, Gs = 2.65. (i) Determine the maximum dry density and optimum moisture content from compaction curve. (ii) Ayer Hitam residual soil will be used as a compacted layer with thickness of 4 m high. If the moisture content of the compacted soil at the field is 15.8%, determine the vertical stress (kN/m³) at a depth of 2.5 m from the ground surface.
