Product Description

Product Use

This instrument is used for indoor simulation of the polishing effect of automobile tires on road surfaces. By accelerating the polishing of the aggregates used on the road surface, the wear resistance of the aggregates can be measured. This provides a scientific basis for selecting suitable surface course aggregates for road sections with different friction coefficient requirements, for the rational development and utilization of stone resources, for shortening the research cycle of anti-skid roads, and for providing technical references for the development of artificial aggregates.
