Three Wheel Polishing Device
Supports the following standards: AASHTO PP103, AASHTO PP104
The New Humboldt 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.
