Supports the following standards: AASHTO PP103, AASHTO PP104 The New M&L Testing Equipment H-3212 Three Wheel Polishing Device is designed to simulate the polishing effects of traffic. Polishing of unbound aggregates per AASHTO PP103 and asphalt mixtures per AASHTO PP104 can be accomplished prior to dynamic friction testing. A staging area facilitates the installation and removal of the molds in the testing area. Electronic actuators lift and lower the wheel carriage onto and off the sample. The VFD allows for a variable rotation of 50-70 rpm from the rugged 1/2hp gear motor. A counter mounted on the electronic controller counts down, stopping the test automatically when the 100,000 rotations are completed.
Specifications Voltage: 115/130VAC 60Hz 1/2hp, three-phase gear motor Variable Frequency Drive (VFD) controlled 115V, 60Hz Submersible water pump RPM range: 50-70

The New, M&L Testing Equipment H-3212, Three-Wheel Polishing Device, is designed to simulate the polishing effects of traffic on asphalt pavement. Polishing of unbound aggregates per AASHTO PP103 and asphalt mixtures per AASHTO PP104 can be accomplished. This video will show you how to do the initial setup and how to run a test. The convenient staging area eases the installation and removal of the molds in the testing area and enables testing with the Dynamic Friction Tester (DFT) before and after polishing the sample. Electronic actuators lift and lower the wheel carriage onto and off the sample. The VFD allows for a variable rotation of 50-70 rpm from the rugged 1/2 hp gear motor. A counter mounted on the electronic controller counts down, stopping the test and water pump automatically after reaching 100,000 rotations.
