Operation CMV
The Compaction Meter is measuring the dynamic
stiffness of the ground. The CMV is influenced by the
rolling speed, rolling direction (forward or reverse),
amplitude setting and vibration frequency. DCM is less
sensitive to small variation in vibration frequency.
Some reference CMV for some compacted materials:
Material CMVMaterial CMV
rock fill 40 - 200rock fill 40 - 200
gravel 25 - 100gravel 25 - 100
sand 20 - 60sand 20 - 60
silt 5 - 30silt 5 - 30
clay 0 - 80clay 0 - 80
The water content in the compacted soil, not rock fill,
has a large influence on stiffness, wet soil will result in
low CMV and dry soil will result in higher CMV.
When double-jump occur CMV will be reduced and
this lower CMV should not be used for determine if
compaction is ready or not.
NOTE: The operator shall always keep an eye on
where they are driving and not focus too much on the
CMV display, due to safety.

Fig. Control panel
1. Working mode

3. Speed selector
Activate the button for the Working mode (1).
Activation of vibration, and also disconnection of
vibration, take place with the switch (2) on the
forward/reverse lever.
Note that vibration can only be activated when the
working mode (1) is activated, and when the speed
selector (3) for the engine is in high (HI) or Eco
mode (ECO). After 10 seconds in neutral, the
vibration is switched off and the machine drops to
low speed.
