2.3 The top 500 mm of a site consists of a clayey sand with void ratio of 0.90 and water content of 20.0%. The specific grav- ity of the soil grains is 2.68. When the ground is compacted at the same water content, there is 45 mm reduction in the thickness of this layer. Determine the new void ratio and the moist unit weight of the soil.
1. The relative compaction of a clayey sand in the field is 90%. In the laboratory, the maximum dry unit weight is 115 ??/??3. If the soil layer before compaction had a void ratio of 0.97 and a thickness of 5.5 ft. What would be the final thickness after compaction? Assume ?? = 2.67.   COMPLETE SOLUTION PLEASE
