• Abstract:
  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 macrotexture tests 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.
