The results from a compaction test are as follows:

a) What is the maximum dry unit weight and optimum moisture content? Use your best approximation.

b) Ben wants to put in an awesome hot tub in his sloped backyard. To do so, it requires construction of an embankment with 1000 ft 3 of soil compacted to specifications of 95% relative compaction. The soil at the excavation site has a dry unit weight of 114 pcf with a moisture content of 6%. How much soil must be excavated to allow Ben to enjoy his hot tub?

c) How much weight of water must be added to the excavated soil to facilitate compaction to the specifications of 95% relative compaction at dry of optimum.
