Impactometer (impacts per meter)
The Impactometer shows how many impacts per
meter the drum performs during vibration, the set
minimum value is shown by a shaded left and right
field on the meter image.
Setting of the minimum value by plus or minus on the
display screen.
The Impactometer value is calculated based on the
operating speed and the vibration frequency. A higher
operating speed gives fewer impacts per meter.
The recommendation is to not fall below 33
impacts/meter (10 impacts/feet) to avoid wave
formation on the road surface.
The choice of high or low amplitude also impacts on
the compaction result and should be taken into
consideration.
