A 3-m high sandy fill material was placed loosely at a relative density of 55%. Laboratory studies indicated that the maximum and minimunm void ratios of the fill material are 0.94 and 0.66, respectively. Construction specifications re- quired that the fill be compacted to a relative density of 85%. If G, = 2.65, determine: Dry unit weight of the fill before and after compaction Final height of the fill after compaction a. b. 202
