One of the main reasons of surface texturing in concrete pavements is to provide a safe surface by supplying adequate surface friction which it could be furnished by different methods on fresh poured concrete. In this way, the hydroplaning and skidding on wet surface would be minimized. However, some other considerations such as safety, quality of driving, bumping noises and economical factor should be noticed. Required specifications should be controlled via width, depth and distance between grooves, amount of noises and grooves direction. In this paper, in order to monitor the surface texturing different classifications, texturing methods, surface properties and measuring methods have been discussed in accordance with American concrete pavement association (ACPA). Finally, different methods of surface texturing in Tehran-North highway are introduced and the results of English pendulum test on each method would be presented. The results indicate that texturing by TCM machine has better English pendulum value even in compare to asphalt overlay.
