The accelerated polishing machine polishes aggregate samples according to real road conditions and is used together with a portable slip resistance test device to determine the polished stone value for aggregates used in road surfaces, providing slip resistance and TPD values. Fourteen samples are placed on sample holders, and the rubber wheel rubs against the holder where the sample is placed, operating in two stages. First, coarse abrasive powder is applied, followed by fine abrasive powder.
