Evib compaction meter (DCM Evib) (Optional)
Compaction meter measures compaction value Evib i
MN / m2
Evib acceleration sensor on the front drum.
Min and max values of the Evib value (Evib 1 or Evib
2) on the relevant compaction meter can be adjusted
by the plus and minus buttons on the display screen.
Evib 1 is calculated during the load cycle (when the
drum is on the way down) during vibration, while Evib
2 is calculated during the load-relief cycle (when the
drum is on the way up). It is up to the user to decide
which value to use.
The best way of determining an Evib measurement
value is to run a test surface with the same
characteristics (substrate, material, temperature,
amplitude and rolling speed, etc.) as the surface to be
compacted and measured.
Compact the surface within the temperature interval
for the asphalt in question, and note the Evib values
for each run. The values should go up slightly with
each run, with increased compaction, and falling
temperature. The value read off for the final run, when
the correct void content/compaction rate is reached,
can then be used as guidance for the minimum or
measured value
However, this must be viewed as indicative only. The
maximum value is set rather higher and should not be
exceeded. High values will occur in the case of low
asphalt temperatures and high compaction levels.
Further vibrating compaction in these cases risks
crushing the stone aggregate, something which should
be avoided.
Always keep track on the asphalt temperature and
relate it to the compaction value. The Evib value will
change not only with the degree of compaction but
also with the asphalt temperature.
"MAIN MENU"
In the main menu it is also possible to change some
user and machine settings, access the service menu
for calibration purposes (special service personnel
only, requires pin code), and to see the version of
installed software.
