This testing instrument is used to determine the Micro-Deval abrasion value of aggregates, evaluating their resistance to wear and mechanical degradation under wet conditions. It can also be applied to assess the abrasion resistance performance of fibers used in asphalt pavement, providing reliable data for material selection, mixture design, and quality control in road engineering.
