Question:

A 2-m-high sandy fill material was placed loosely at a relative density of 47%. Laboratory studies indicated that the maximum and minimum void ratios of the fill material are 0.92 and 0.53, respectively. Construction specifications required that the fill be compacted to a relative density of 80%. If Gs = 2.65, determine:
a. Dry unit weight of the fill before and after compaction
b. Final height of the fill after compaction
