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).

  • Polish paver-value determination uses the BS812 aggregate abrasion method to polish the samples of pavers
  • 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
  • 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
