Figure below shows the moisture$-$dry unit weight relationship established from a standard Proctor compaction test set for a compacted clay embankment section. The specific gravity of the soil grains is $2\mathrm{.}72.$ The compaction specification requires that the clay be compacted in the field to relative compaction of $95\%$ with respect to modified Proctor compaction tests and the water content lies in the range of $16\mathrm{.}0\%$ to $19\mathrm{.}0\%.$

Once the clay is compacted in the field, control tests were carried out at four different locations using a nuclear density meter, and the moisture content and dry unit weight were measured as follows. Check and discuss whether the field compaction meets the specifications at the four locations. $(2$ marks$)$
