The water content in the compacted soil, except for rockfill,
has a large influence on stiffness; wet soil will result in low
CMV and dry soil will result in higher CMV.
When bouncing occurs, CMV will be reduced and this
lower CMV should not be used for determine if compaction
is ready or not.
NOTE: The operator should always focus on the direction
of driving and not too much on the CMV display for safety
reasons.
