Polish Paver Machine

Clear

The Polish Paver Machine specifically designed to meet international standards for the determination of the Polished Paver Value PPV

The polish paver-value determination follows the BS812 aggregate abrasion method to polish the samples of pavers. The abrasion lap is modified by attaching a standard rubber disk. Corn emery and emery flour abrasives are fed to the samples under test as in the BS812 determination. The specimens are prepared to aggregate abrasion test specimen dimensions. Flat control specimens (of the same control stone as the PSV test) are also made to these dimensions.
After completion of the polishing procedure, the degree of polish is measured with the Pendulum Skid Resistance test in a similar way to the PSV test. A flat to curved correction factor is then applied to estimate the ‘polished-paver value’; a correction being applied in the same way as the PSV test according to the level of the control specimens. The method has been published by the British Standards Institution a draft for development (DD 155). It also forms the basis of the draft European Standard.
