History
What is “intelligence”
What is “intelligence”“… the ability to adapt its behavior in response to varying situations and
requirements”
Vario Directed Exciter
From Horizontal to Vertical 6 Force Outputs Created by Vectoring

The Traditional Way of Compacting Soil
• High or Low Amplitude Choices• Pre-defined number of passes –
Possibly or Experience• No real time information on load bearing
capacity or progress on achieved stiffness
• Potentially Low Efficiency • Potentially Low Effectiveness• Contractor loses time and money• Material can be crushed• Roller potentially damaged• Compaction quality compromised
Variocontrol Benefits
• Exceptional Compaction Performance• Increased Depth Effect• Thick Lift Compaction• Wide Range of Adaptability• Consistent Compaction Quality• Proof Rolling to identify soft spots• P.R. to confirm previous work• Under Compaction is avoided• Over Compaction is avoided• Unnecessary Passes are avoided• Pre-selected limits can be selected
