One of your junior engineers has submitted a construction quality (CQC) plan for your review before it is sent to the client. The CQC plan includes a compaction specification for the compacted clay liner. The specification requires that the clay be compacted to a dry unit weight 92% of maximum dry unit weight (standard Proctor) and wet of standard Proctor optimum water content. Compaction and hydraulic conductivity-water content curves for the soil are shown in the figure below. The clay liner is required to have hydraulic conductivity1 x 10-7cm/sec. Find the acceptable zone based on hydraulic conductivity. Does this specification ensure that the required hydraulic conductivity will be obtained? Part II: Explain the shape of the standard Proctor compaction and hydraulic conductivity-water content curves (above) in terms of the shear strength and fate of clods during compaction
