Diamond grinding is a procedure used to restore or improve pavement ride quality and surface texture. Although diamond grinding has been an available restoration procedure since the 1960's, recent developments and increased experience have made diamond grinding and concrete pavement restoration the best first rehabilitation option for concrete pavements.

pavements (silent) and for concrete road revival (sustainability). This technique was first used in 1965 on a 19 year of section of I-10 in Southern California to eliminate excessive faulting. Since then, diamond grinding has become a major element of concrete pavement restoration project in the USA.

Hot forging is most commonly used for gears. Maximum and highly uniform density is ensured by complete filling of forging die. During forging or upsetting, material grain is made to flow at right angle to the direction of the stress on gear teeth in actual dynamic loading. Uniform grain flow also reduces distortion during heat treatment.

A cold milling drum is illustrated in Figure B-3. Infrequently, cold milling is done without subsequent resurfacing, to remove rutting and/or bumps, and/or to improve surface friction. In this case, a finer surface texture is obtained using special cold milling drums, with two to three times more carbide bits than on a normal cold milling drum.
