Grinding Diamond grinding is the removal of a thin (generally about 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. Major appliions for diamond grinding are to remove surface irregularities (most commonly joint faulting or joint elevation differences ...

Rigid Pavement Design ... Diamond Grinding. ♦ Introduction ... when the existing pavement is badly deteriorated because a reduced amount of repairs were made to the existing pavement prior to constructing the unbonded concrete overlay. Unbonded CRCP concrete overlays may be used over CRCP, jointed concrete pavement (CPCD), or jointed reinforced concrete pavement (JRCP). .
Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as minor pits and divots, faulting and roughness on concrete pavements. This is achieved by using diamond bits to grind the surface. This also leaves a very smooth profileideal for thinmil coating or sealer appliions. Diamond grinding also profiles the concrete and removes contaminants from the ...

Diamond Grinding. ♦ Introduction ... Compared with repair/rehabilitation of flexible pavement, rigid pavement repair/rehabilitation costs more and, if not done properly, similar distresses will develop in close proximity, and additional repair/rehabilitation will be required. Developing optimum repair/rehabilitation strategies requires the understanding of the causes and mechanisms of ...
Pavement surface repair (diamond grinding) shall consist of grinding and texturing the concrete surface in a longitudinal direction. The ground surface shall be of uniform texture. When more than one grinding machine is used in the same travel lane, the blade segment thicknesses, blade spacings, and blade diameter shall be similar so that the texture of the ground surface is reasonably uniform ...
· For rigid pavements, the most recommended preservation treatment is crack and joint sealing and corner repair, followed by diamond grinding . This recommendation is almost independent to the available budget, as results are very similar for low .

Diamond Grinding Was Invented in California ¡Diamond grinding was first used in California in 1965 on a 19year old section of I10 to eliminate significant faulting (Neal and Woodstrom 1976). ¡In 1983, CPR was conducted on this same pavement section, including the use of additional grinding .
