In the field, the relative compaction (RC) of a sandy road foundation is 90%. Ya(max) = 20.4 kN/m and Ya(min) = 13.9 kN/m2 are the maximum and minimum dry unit weights of sand, respectively. Calculate the field values of the following: a) the dry unit weight in the field; b) the relative density (of compaction) D; and c) the moist unit weight y with a moisture content of 15%.
