2. (15) The relative compaction of a sand in the field is \( 85 \% \). The maximum and minimum dry unit weights of the sand are \( 18.5 \mathrm{kN} / \mathrm{m}^{3} \) and \( 15.4 \mathrm{kN} / \mathrm{m}^{3} \), respectively. Determine: a. Dry unit weight in the field, b. Relative density of compaction, and c. Moist unit weight at a moisture content of \( 13 \% \)
Expert Answer
Solution Relative Compactness R = 85% 2 a. Dry Unit Weight R=?dry?dmax?dry=R×?dMax=0.85×18.5 kN/m3=15.725 kN/m3 So,Dry unit weight is 15.725 KN/m3
