Diamond grinding offers a more permanent solution and is a cost-effective procedure to repair PCC pavement roughness, increase friction and reduce tire/pavement noise. The carbide milling process is not a substitute for diamond grinding when performing surface restoration and improvement on concrete pavement. Diamond grinding of concrete pavement leaves a surface which is often as good as new pavement.

Carbonation is one of several ways that concrete contributes to sustainability. In typical pavement, approximately 2-3mm of carbonation may occur in the first 2-3 years whereas by year 20, the total depth of carbonation is only 5-8mm, with little additional carbonation occurring beyond year 50. The most practical way to counteract this decrease is to remove the carbonated surface with diamond grinding.

This study highlights the advantages of diamond grinding in optimizing pavement performance and customer satisfaction. Diamond grinding significantly reduces road noise by providing a longitudinal texture, enhancing surface macrotexture and skid resistance. Additionally, the study touches on diamond grooving, which involves sawing discrete drainage channels into the pavement to improve safety, particularly in wet conditions. The Next Generation Concrete Surface (NGCS) is also explored, combining diamond grinding and longitudinal grooving to create a quieter, more durable pavement surface

The comparative benefits of production grinding versus bump grinding are explored in this study for optimizing pavement performance and cost-efficiency. Diamond grinding is emphasized as a crucial technique for smoothing pavement surfaces, with production grinding covering the entire lane width and length to achieve superior results in ride quality, friction, sound reduction, fuel efficiency and aesthetics. While bump grinding—targeting only uneven areas—can improve ride quality and extend pavement life, production grinding often proves more economical and effective overall.

Nearly every concrete road repair project raises the question of how to handle the resulting concrete residue, or slurry, generated during sawing and diamond grinding operations. In an attempt to clarify these issues, the IGGA in 2009 entered into a research project with North Dakota State University (NDSU). This research studied CGR from different areas across the country.

The choice of road repair methods can save fuel and reduce dependence on oil imports. Diamond grinding and joint resealing a concrete pavement is three times more energy efficient than a typical asphalt overlay.
