Balanced Mix

The Humboldt H-3212 Three-Wheel Polishing Device is a cutting-edge solution designed to replicate the polishing effects of traffic, providing reliable, repeatable asphalt and aggregate testing results. Whether you're testing unbound aggregates or asphalt mixtures, the H-3212 ensures your samples are thoroughly prepared for dynamic friction testing in accordance with AASHTO PP103 and AASHTO PP104 standards. Key Benefits of the H-3212: Realistic Wear Simulation: Simulates traffic wear patterns for reliable performance prediction. Versatile Application: Conducts polishing of both unbound aggregates and asphalt mixtures. The VFD allows for variable speed control from 50-70 rpm. User-Friendly: The convenient staging area simplifies mold placement and removal, enabling easy integration with Dynamic Friction Testers (DFT) for pre- and post-polish friction testing. Electronic actuators handle lifting and lowering the wheel carriage. Automated Operation: The integrated counter automatically stops the test and water pump after 100,000 rotations, ensuring consistent and repeatable results.
