Diamond grinding is the removal of hardened Portland cement concrete (PCC) through the use of closely-spaced, diamond saw blades mounted on a rotating drum. Diamond grinding is used for the removal of bumps or scallops that cause poor ride quality and to restore surface texture, improving overall friction. The surface characteristics of the pavement after grinding are highly dependent on the blade spacing, which is highly dependent upon the hardness of the aggregate. Newly developed textures can also reduce tire-pavement noise.
