1) What is the purpose of soil compaction? Why is it useful? 2) Why does a compaction curve go up and then back down with increasing moisture content? 3) How does the location of the compaction curve in densitylmoisture content space change with increasing energy? Why? 4) Why do we engineers provide specifications (i.e., relative compaction limits and allowable moisture contents) to contractors? What is the usual consequence for not compacting the soil in accordance with the specifications? 5) Which method is more accurate: the sand cone or the nuclear density gauge? Why?
