This report presents data showing the effect that pavement surface has on the generation of truck tire noise. Three different tread designs -- rib, cross-bar and pocket -- were tested at speeds of 40, 50 and 60 mph (64.4, 80.5 and 96.5 km/hr) while coasting on eight different pavement surfaces at the Texas Transportation Institute. These surfaces represent a wide range of surface texture. Also presented are the results of one method of quantitatively characterizing pavement surface texture; namely, the mean square value of the macrotexture profile, obtained utilizing a macrotexture profile tracer. Because of the wide variation in noise level with changes in surface texture for the pocket retread, this tire is investigated as a possible simple calibrator of surface texture.
