Accelerated Polishing Machine
Short info :
The accelerated polishing machine polishes samples of aggregates, simulating actual road conditions, and is used in conjunction with the portable skid resistance tester to determine the polished stone value for aggregates used in road surfaces, and gives a measure of the resistance to skidding. Fourteen specimens are clamped around the "road wheel" of the polishing machine, and subjected to two stages of polishing by a loaded rubber tire. First by corn emery, and secondly by emery flour. Use of the accelerated polishing machine and the skid resistance tester in road construction has had a major influence in reduction of accidents.
