What is Diamond Grinding? Removal of thin surface layer of pavement surface using closely spaced diamond saw blades Results in smooth, level pavement surface Provides a longitudinal texture with desirable friction and low noise characteristics Frequently performed on pavements to improve smoothness, increase friction, repair profile/drainage and reduce tire/pavement

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 stand-alone rehabilitation technique.
CHAPTER 5DIAMOND GRINDING AND GROOVING December 19, 2007 5-5 5.2.2 Design Parameters Diamond Grinding The three design parameters shown in Figure 5-4 vary over a fairly narrow range of values. The groove is usually 0.10-0.13 inches (2.5-3.5 mm) wide with a depth of 0.05 to 0.2 inches (1.5 to 5 mm).
Diamond grinding may be used on asphalt surfaces but is typically a shorter-term treatment in these applications. Diamond grinding may be performed as a stand-alone treatment or in combination with diamond grooving. Because of the equipment mobilization costs, diamond grinding is more appropriate for longer applications. Refer to PDM Section ...

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 1960s, recent developments and increased experience have made diamond grinding and concrete pavement restoration the best first rehabilitation option for concrete pavements.
4.1 PAVEMENT DESIGN 1. Florida is among the majority of states using the 1993 AASHTO Guide. Florida currently allows the use of the Mechanistic-Empirical Pavement Design Guide (MEPDG) as an alternate design method. 2.

Jan 15, 2021 Diamond grinding is often performed in combination with repairs or load transfer retrofit as a minor rehabilitation project rather than a surface treatment. 556.1 Project Selection. The pavement management system provides a yearly list of recommended diamond grinding candidates based on the optimized solution.
Crews can diamond-grind concrete pavements up to three times before major reconstruction is needed. Combined with routine maintenance, diamond grinding can extend the service life of a pavement to twice its normal design life. Plus, diamond grinding is done during off-peak hours, thereby minimizing disruption to traffic flow.

The main difference between diamond grinding and carbide milling is in the way that the cutting head removes the concrete layer. Diamond grinding uses closely spaced, diamond saw blades that gently abrade away the top surface of the concrete. On average, the diamond cutting media will contact the pavement surface nearly 27,000,000 times per ...
Diamond grinding is a rigid pavement preservation treatment which is typically utilized to increase pavement smoothness by eliminating the surface undulations. The
Longitudinal grooving removes pavement conditions such as warp and curl for improved ride quality Evidence shows that the improvement benefits from diamond grinding retextured concrete last up to 10 years and, where pavement structure is sound, can be re-machined two more times to extend life further.
