Diamond grinding (DG) removes a thin layer at the surface of hardened PCC pavement using closely spaced diamond blades. DG used to be an expensive operation; however, new, highproduction equipment as well as improved synthetic diamonds for saw blades made DG a more cost competitive option for PCC pavement rehabilitation.
pavements and where diamond grinding may be required over a significant length of pavement. It may be used for single or multiple lane grinding. Specification R93 is less suitable than M229 for use for diamond grinding of very old jointed reinforced concrete pavements in urban areas.
Grinding shall be done using diamond blades mounted on a selfpropelled machine designed for grinding and texturing pavement. The equipment shall be a minimum 35,000 pounds, including grinding head, and of a size that will grind a strip at least 3 feet wide. The effective wheel base of the machine shall be no less than 12 feet.
28 Jun Diamond Grinding for Local Roads Posted on Jun 28 2020 Diamond grinding is the removal of a thin layer of hardened concrete pavement surface using a selfpropelled machine outfitted with a series of closely spaced diamond saw blades mounted on a rotating shaft.
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 develop#173;ments and increased experience have made diamond grinding and concrete pavement restoration the best first rehabilitation option for concrete pavements.

Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as faulting and roughness on concrete pavements. Diamond grinding should be used in conjunction with other Concrete Pavement Rehabilitation (CPR) techniques. A full CPR job can restore structural and functional capacity of a pavement to acceptable levels

Diamond grinding consists of removing surface irregularities from concrete pavements that are often caused by faulting, curling, and warping of the slabs. The main benefits of properly using this technique include smoother ride, reduced road noise, and improved friction. Diamond grinding can be used as a standalone rehabilitation technique.
CHAPTER 5DIAMOND GRINDING AND GROOVING December 19, 2007 55 Design Parameters Diamond Grinding The three design parameters shown in Figure 54 vary over a fairly narrow range of values. The groove is usually inches ( mm) wide with a depth of to inches ( to 5 mm).
Diamond grinding (Figure 1) refers to a process where gangmounted diamond saw blades (Figures 2 and 3) are used to shave off a thin, 19 mm ( 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
