Relationship between Mineral Characteristics and Frictional Property of Pavement Stones

Abstract:

In order to study the impact of stone mineral composition and micro-structure on its frictional properties, 3 pavement stones used commonly were selected and researched experimentally. In the research, the frictions were measured by the specially designed facility of the State Key Laboratory of Tsinghua University and the mineral characteristics were conducted by the flake inspection, respectively. In addition, the Polishing Stone Value, abrasion value, impact value and crushing value of the 3 stones was tested. The results denote that the broader the size distributing range of compositing minerals and the greater the hardness, the larger the frictional coefficient, which indicates the mineral characteristics of pavement stones are especially essential for frictional property.
