A sand cone test was conducted in the field. The mass of wet soil excavated from the hole is 3668.3g with a moisture content of 17.2%. Before and after the test, the sand cone apparatus weighed 10154.0g and 5749.4g. The cone can contain 1680g of Ottawa Sand (ρ=1.353g/cc). If the maximum dry density of the soil is 1.702g/cc, calculate the relative compaction.
Laboratory compaction test results and fielddetermined in-place density (unit weight) results are reported in terms of dry density or unit weight and not wet density or unit weight. Outline the reasons for this procedure of reporting. (Hint: Consider the soil properties directly related to density or unit weight.)

Since laboratory or field experiments are generally expensive and time consuming, geotechnical engineers often have to rely on empirical relationships to predict design parameters. Section 6.6 presents such relationships for predicting optimum moisture content and maximum dry unit weight. Let us use some of these equations and compare our results with known experimental data. The following table presents the results from laboratory compaction tests conducted on a wide range of fine-grained soils using various compactive efforts (E). Based on the soil data given in the table, determine the optimum moisture content and maximum dry unit weight using the empirical relationships presented in Section 6.6. a. Use the Osman et al. (2008) method [Eqs. (6.15) through (6.18)]. b. Use the Gurtug and Sridharan (2004) method [Eqs. (6.13) and (6.14)]. c. Use the Matteo et al. (2009) method [Eqs. (6.19) and (6.20)]. d.
