The role of macro-texture in imparting friction capabilities to pavement surfaces is of major concern to researchers. Macro-texture is but one of the many variables affecting the interaction at the tire-pavement interface; however, at present its relative importance is questioned. Friction tests obtained at 20, 40, and 60 mph with the Texas Highway Department research skid trailer, and macro-texture utilizing four different methods were conducted on forty-one pavement surfaces. These surfaces exhibited widely different friction levels, friction-speed gradients, drainage capabilities, mineralogical properties, and texture classifications. Macro-texture values obtained with the four methods are compared. (Author)
