Question

The following are the observed lab values for determining the maximum dry unit weight of the soil. (See table below)

  • Determine the optimum moisture content in percent (3 decimals)
  • Determine the maximum dry unit weight, in kN/m(round off to the nearest 10th)
  • How much water (in kg) must be added per m3 of soil to achieve maximum dry unit weight if initially the moisture content of the in-situ soil before testing was 6%?
