Concrete diamond grinding removes roadway imperfections caused by construction and/or heavy usage. The immediate result is an improvement in pavement smoothness, surface texture, skid resistance, safety, and noise reduction.
Deeper diamond grinding will expose the coarse aggregate in the concrete pavement. Softer coarse aggregates that are exposed may polish and result in lower skid numbers. The department developed special specifications for diamond grinding.
DSI started as a diamond grinding contractor in 1989. Our reputation is solid in the grinding industry as a leader and innovator. We believe that diamond grinding is the best alternative to short lived, more expensive methods.

The presentation basically deals with the diamond grinding of concrete pavements . One can get a clear picture of the whole process of diamond grinding which has proved to be an efficient pavement preservation technique in the alst decade.
concrete pavement, which means that some asphalt is being removed by the diamond-grinding equipment while profiling the old concrete pavement to a satisfactory ride. The project is located on Highway 21 on the north side of Newark, New Jersey.
diamond grinding of older concrete pavements, particularly in urban areas, are set out in Roads and Maritime specification M229. A list of diamond grinding and associated road specifications
Diamond Grinding . The purpose of diamond grinding is to remove bumps and reprofile the surface of concrete pavements. This improves the riding comfort to motorists and decreases the severity of dynamic or impact loads from heavier vehicles.
Diamond Grinding of Portland Cement Concrete Pavements Checklist This checklist is one of a series created to guide State and local highway maintenance
Diamond grinding is a well-established technology that has been utilized extensively since the 1960s to provide a smooth yet textured surface for existing concrete pavements that …
Diamond Grinding PRS offers high horsepower tier four engine diamond grinders as a maintenance solution for concrete and asphalt pavements. Corrective grinding provides a cost-effective solution to eliminate unsafe surface bumps and create a smooth finish.
Nov 18, 2013· Concrete texture-planning is used to improve skid resistance, correct surface defects and promote drainage. This video will review this process from Minnesot...
Diamond grinding is a concrete pavement restoration process that renews a worn or slightly irregular surface. Diamond grinding can potentially remove or reduce some pavement deficiencies such as joint faults resulting from minor pavement settlement, worn pavement from wheel rutting, warped slabs, and a rough surface texture.
Diamond grinding of concrete pavements is a common approach in NSW to treating the surface of concrete pavements during construction to improve ride quality or for existing pavements to achieve one or all of the following: • improvements to ride characteristics and surface profile correction.
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.
Diamond grinding of Portland cement concrete pavements and micro-milling of bituminous asphalt pavements are superficially similar in concept, but that's just about the only thing they have in common.
Publication Details Concrete Pavement Rehabilitation - Guide for Diamond Grinding . Primary Topic: Pavement Rehabilitation. Description: Document briefly summarizes diamond grinding technique for rigid pavement restoration and discusses the concept, equipment, advantages, design considerations, construction, performance and costs.The document also provides an example guide specification.
This 51-year-old pavement is an excellent showcase of the endurance and durability of concrete pavements and effectiveness of CPR with diamond grinding. Though the 1997 survey showed low-severity cracking, further extension of the service life is expected due to grinding.
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

Diamond grinding is a concrete pavement rehabilitation technique that corrects irregularities such as faulting and roughness on concrete pavements. Diamond grinding should be used in conjunction with other concrete pavement rehabilitation techniques.
In Germany, diamond grinding is frequently used to improve the evenness and skid resistance of concrete pavement surfaces. Since diamond grinding has been observed to affect tyre/pavement noise emission favourably, the relationship among surface texture, concrete composition and noise emission of concrete pavement surfaces has been systematically investigated.
