A soil in its natural ground state is at dry density of 1700 kg/m3 with water content of 12% and solids specific gravity of 2.70. A barrowed soil material of 2000 cubic meter volume is excavated from the ground and transported elsewhere as to be used in the construction of an embankment. The compacted embankment has a porosity ratio of 0.32. a) Calculate the volume of the embankment that can be constructed out of this material. b) Would it be wise to pay for the transported soil material by weight or volume? Why?
