Accelerated Polishing Machine (PSV) is used to simulate the polishing action of vehicle tires on a road surface, for coarse aggregate which is going to be used as asphalt road surface covers.
Abrasive Corn Emery is fed to the point of contact of the wheel on the test surface for 3 hours, followed by feeding Emery Flour to polish the surface being tested for a further 3 hours. Subsequent skid tests are carried out on the test samples using suitable portable skid test equipment.
