Evolution of road-surface skid-resistance and texture due to polishing

In this paper, works are conducted to have a better understanding of the evolution of the road-surface texture due to traffic polishing. Examples are shown for two aggregates having respectively low and high - polishing-resistances. Surface profiles measured at different polishing stages are analyzed. Roughness parameters characterizing asperity height and sharpness are calculated and their evolution is compared with the friction evolution.
