Microtexture, usually defined as small-scale texture up to 0.5 mm wavelengths, is largely a function of the surface texture of aggregate particles, while macrotexture is a larger texture between about 0.5 mm and 50 mm wavelengths (1.2).Of the two texture types, microtexture affects the adhesion area between aggregate and tire rubber and controls the pavement friction level at low speeds, while macrotexture has a greater effect on hysteresis friction.Unlike microtexture, macrotexture also helps to provide a drainage channel for water to escape
