Key Performance Features

• Dual-Wheel Testing: Features two independent testing stations for simultaneous or staggered testing, maximizing laboratory throughput.
• Air & Water Conditioning: Equipped with high-precision circulation for both dry rutting and wet “stripping” analysis (AASHTO/EN).
• Direct Drive System: Utilizes a heavy-duty motor to maintain constant speed and sinusoidal motion for millions of cycles.
• Ergonomic Loading: Designed with a sliding carriage system for effortless loading of slabs or gyratory compacted samples.
• Smart Software: Provides real-time plotting of rut depth vs. passes and automated calculation of the “stripping point.”
