The soil from Problem 1 is used in the construction of an embankment. The specification for compaction states that the compacted field soil must be at least \(98\%\) of the maximum dry unit weight, and within \(+/-2\%\) of the optimum water content for the standard compaction curve. In the field, a sand cone test was performed to determine the quality of the field compaction. A hole was dug in the compacted soil to collect a sample that weighs 5.283 lbs wet and 4.675 lbs dry. Then, the hole was filled by the Ottawa sand. The collected data are given below:
*Note: the standard energy laboratory compaction test on the soil is shown in Problem 1.
a) What is the dry compacted unit weight and water content of the compacted lift? What is the percent compaction (Relative Compaction)? Does the sample meet the specifications?
b) What is the compacted degree of saturation?
c) If the compacted sample were saturated, what would the water content be?
