DescriptionKey FeaturesSpecificationsAccessoriesDatasheet Accelerated Polishing Machine is used to produce polished stone samples of aggregates used in road surfaces, to stimulate actual road conditions.In 1950 increased traffic flow and higher speeds, together with concerns about road safety led to research into the relationship between road materials and skid-resistance. Research at the UK Transport Road Research Laboratory showed a significant relationship between polishing of aggregates used in road surfaces and skid resistance. Tests were devised using an Accelerated Polishing Machine and a friction measuring device (known as the Pendulum Skid Tester, also supplied by Cooper-Wessex), to determine a Polished Stone Value (PSV).Fourteen specimen aggregate samples are clamped around a rotating Road Wheel. These samples are subjected to two timed stages of abrasive polishing under a loaded rubber tyre. First by Corn Emery grit, and secondly by Flour Emery powder.As the best quality market leaders Cooper-Wessex have recently been copied by low quality manufacturers. Imitators’ machines may look similar, but precision, repeatability and reproducibility come only with years of experience. High ground steel main spindle running in precision sealed ball bearings additionally protected by a labyrinth seal spindle axially loaded to eliminate end play.Adjustable 3 phase motor speed control with adjustable timing belt drive, reducing power consumption and improves control.Inverter drive to motor for precise speed controlDigital display preset timer and revolution counter.Robust welded steel mainframe, standing on adjustable padsSpecimens manufactured and easily removed from precision machined moulds.14 Specimens located on ‘Road Wheel’ by rubber rings and held by simple side fixing.Tyred wheel easily removed for replacing tyres.Water gravity fed from high level tank through calibrated flow meter.Used abrasive and water collected in easily removable tray.Loaded tyre raised and lowered to the running surface by mechanical lifting device.Protection by covers and guards may be easily removed for maintenance.CE marked.ASTM option with pneumatic wheel.

Accelerated Polishing Machine is used to produce polished stone samples of aggregates used in road surfaces, to stimulate actual road conditions.
In 1950 increased traffic flow and higher speeds, together with concerns about road safety led to research into the relationship between road materials and skid-resistance. Research at the UK Transport Road Research Laboratory showed a significant relationship between polishing of aggregates used in road surfaces and skid resistance. Tests were devised using an Accelerated Polishing Machine and a friction measuring device (known as the Pendulum Skid Tester, also supplied by Cooper-Wessex), to determine a Polished Stone Value (PSV).
Fourteen specimen aggregate samples are clamped around a rotating Road Wheel. These samples are subjected to two timed stages of abrasive polishing under a loaded rubber tyre. First by Corn Emery grit, and secondly by Flour Emery powder.
As the best quality market leaders Cooper-Wessex have recently been copied by low quality manufacturers. Imitators’ machines may look similar, but precision, repeatability and reproducibility come only with years of experience.
