Fig. Asphalt temperature screen
Asphalt temperature meter
Asphalt temperatures are shown either in Celsius or
Fahrenheit. (selected in User settings)
Dual temperature sensors, one front and one rear.

The sensor that sits foremost in the current direction of
travel is highlighted and it is this one that is read to
avoid the disruption of moisture from the drum’s
sprinklers. The sensor that is rearmost in the current
direction of travel is shaded/dimmed.
Setting of max. and min values by plus or minus on
the display image, the temperature area will be green
if the temperature keeps within the desired values and
turns yellow if the temperature is higher than the
maximum value.
(asphalt temperature limit min 50°C, max 150°C
(min 122°F, max 302°F))
Fig. Impactometer screen
Impactometer (strokes per meter)
The Impactometer shows how many strokes per meter
the drum performs during vibration, the set minimum
value is shown by a blue arrow on the meter image.
The green area in the image shows our basic
recommendation for the speed interval.
Fig. Impactometer value
Min
Setting of the minimum value by plus or minus on the
display image.
The Impactometer value is calculated based on the
operating speed and the vibration frequency. A higher
operating speed gives fewer strokes per meter.
The recommendation is to not fall below 33
strokes/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.
