RPMTAG Chapter 5 Diamond Grinding and Grooving

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

What are Highway Rain Grooves and Why Do They Make Them

These freeway grooves are created through a process called “diamond grinding” and as the name suggests diamonds are attached to groups of saw blades which are then used to treat road surfaces by digging the grooves into them. Industrial-grade diamonds are mixed with metallurgical powder, the composition of which is determined by the type of pavement that is being reconditioned.

Metallographic grinding and polishing insight Struers

Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time. Grinding removes material using fixed abrasive particles that produce chips of the specimen
