LS-VIB-55 Vibratory Slab Compactor
LS-VIB-55 Vibratory Slab Compactor is a asphalt slab compactor for laboratory specimens for EN 12697-32 workflows. Features a 55kN dynamic load system — equivalent to field steel-roller compaction — with Japan-sourced variable frequency control to precisely simulate realistic site-specific air-void distributions.
Programmable 4-Stage Simulation Flow
The LS-VIB-1's primary competitive advantage lies in its proprietary 4-stage programmable compaction cycle. Users can independently define pressure, vibration frequency, and rolling passes for each stage, allowing for an incredibly high-fidelity simulation of complex multi-pass field rolling protocols.
55 kN Heavy-Duty Load Architecture
Engineered to replicate the intensive stresses of field vibratory rollers, the high-performance load system provides a 55 kN equivalent static/dynamic force. This creates realistic specimen densities and air-void structures essential for advanced rutting and fatigue research.
Inverter-Driven Frequency Precision
Utilizing a high-stability Panasonic variable frequency drive (VFD), the system maintains seamless control from 0 to 50 Hz. This precision ensures that the test simulation complies with the specific energy requirements of EN 12697-32 and sophisticated mix-design projects.
Failsafe Triple-Gate Safety Shield
Prioritizing laboratory personnel safety, the unit is encased in a triple-gate interlock cage. The external air supply powers advanced pneumatic logic that immediately cuts all mechanical and electrical energy upon any door opening, preventing accidental deployment or misuse.
