Diamond grinding of pavement — Wikipedia .

    When grinding materials contain hard aggregate materials, a diamond blade with a soft bond is needed, which means that the metallurgical powders in the cutting segments of the blade wear fast enough to expose the diamond cutting media at the proper rate for efficient cutting. Conversely, to cut soft aggregates, a diamond blade with a hard bond is recommended.

    Diamond grinding is one of the most cost effective concrete pavement restoration (CPR) techniques. It consists of "grinding" 3/16 to 1/4 inch (5 to 7 mm) of the surface of jointed plain concrete pavement (JPCP) using closely spaced diamond saw blades. The result is a level, smooth, and generally quieter riding surface. The closely spaced grooves left after grinding give the riding surface ...
