Grinding Diamond grinding is the removal of a thin (generally about 0.25 in. [6 mm]) layer of concrete from the surface of the con- crete pavement. Sawing is accomplished using special equip- ment outfitted with a series of closely spaced diamond saw blades.

Dowel bar retrofitting is a method used to restore or provide better load transfer across transverse joints or cracks using dowel bars.Usually, dowel bar retrofits are necessitated by excessive faulting due to a loss of aggregate interlock over time. It is interesting to note that much of the rigid pavement built in the U.S. during the 1950s and later included dowel bars for load transfer ...

Diamond grinding (Figure 1) refers to a process where gang-mounted diamond saw blades (Figures 2 and 3) are used to shave off a thin, 1.5 – 19 mm (0.06 – 0.75 inch) top layer of an existing PCC surface in order to restore smoothness and friction characteristics. Most often, it is used to restore roadway friction or remove roughness caused by faulting, studded tire wear, and slab warping ...

Diamond Grinding Was Invented in California ¡Diamond grinding was first used in California in 1965 on a 19-year old section of I-10 to eliminate significant faulting (Neal and Woodstrom 1976). ¡In 1983, CPR was conducted on this same pavement section, including the …

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.
