Question

Given the optimum moisture content = 15.5%, max total unit weight = 21.6kN/m3, max dry unit weight = 18.7 kN/m3

(b) The above soil was used to build an embankment that is to be compacted to a relative compaction
of 99%. In order to control the quality of the field compaction, three sand cone tests were performed at
three different locations on the finished embankment, and the results were found to be as follows:
Test No.
Volume of hole (cm³)
Weight of soil extracted (g)
