ASPHALT MANEGER (BOMAG)
,
Asphalt Manager (Bomag): Oscillation alignment system which enables stepless adjustment to the direction of compaction force between vertical and horizontal. The maximum possible output is provided, based on a calculation of the rigidity of the material being compacted. Compaction process is calculated continuously and displayed as an EVIB value on a special display, the BOMAG Operational Panel (BOP). The display also informs the operator of the current asphalt temperature, the rolling speed and the currently active amplitude.
Two operating modes:
+ Automatic mode: The roller operator does not need to make any manual settings. Amplitude is automatically adjusted to conditions.
+ Manual mode: The operator can preselect one of six oscillation directions between vertical and horizontal.
