Polish Paver Machine
The Cooper-Wessex Polish Paver Machine CRT-PPM is specifically designed to meet international standards for the determination of the Polished Paver Value (PPV)
The polish paver-value determination makes use of the BS812 aggregate abrasion method to polish the samples of pavers. The abrasion lap is modified by attaching standard rubber disk and corn emery and emery flour abrasives are fed to the samples under test in the same way as in the BS812 determination. The specimens are prepared to aggregate abrasion test specimen dimensions and 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
