3.C.1 It is known that the natural soil at a construction site has a void ratio of 0.92. At the end of compaction, the in-place void ratio was found to be 0.65. If the moisture content remains unchanged, determine the following: a. Percent decrease in the total volume of the soil due to compaction b. Percent increase in the eld dry unit weight c.
