This paper aims to investigate the evolution of aggregate-surface characteristics due to tyre polishing action. Three kinds of aggregates were polished by the Wehner/Schluze polishing machine. The evolution of dynamic friction coefficient, surface height profiles and their power spectral density in polishing process were characterized. Spectrum analysis is conducted to characterization the polishing effects on surface texture. The results reveal that the polishing action of rubber tyre plays an important role in the changes of micro-texture, and the evolution of friction of aggregate is governed by micro-texture changes due to differential removal of mineral components.
