• Abstract:
  Data are presented relating the various pavement surface characteristics, operating modes of tires, and field methods of measuring skid numbers for different pavement surfaces. Void areas were determined for 41 pavement surfaces and correlated with the reduction in skid numbers caused by an increase in speed from 20 to 60 mph. The correlation coefficients were statistically significant. Void areas of highway surfaces can be increased by increasing the macro-textures of the surface to obtain small decreases in skid number with increased speed. Microscopic textures and small-scale macroscopic textures (in terms of centerline average heights) are also significantly correlated with the skid number measured by a skid trailer equipped with a standard E-17 test tire.
