Specifications require that a fill using borrow soil to be compacted at 95% of its standard proctor maximum dry density. Tests indicate that this maxi-mum is 19.5 kilo Newtons per cubic meter with 12 % moisture. The borrow material has a void ratio of 0.60. Compute the minimum dry and wet unit weight of the compacted soil, compute also the minimum volume of borrow material required to fill 1 cubic meter when compacted. Assume a logical value of Gs with at least 4 significant figures.
