In response to noise complaints received by the Ohio Department of Transportation (ODOT), I-75 in Troy, Ohio was rehabilitated using diamond grinding and dowel bar retrofit (DBR) to maintain pavement smoothness and extend lifespan. The project also included the removal of the existing transverse tined surface and diamond grinding of four small bridge overpasses. The work resulted in noise reductions ranging from two to nine decibels and a smoother ride. These techniques proved effective in enhancing pavement performance and durability.

I-90 in Wall, South Dakota underwent rehabilitation with diamond grinding, covering asphalt to improve ride quality and safety. This technique proved to be a cost-effective alternative to traditional milling and overlaying, reducing costs by 67% to 75%. The project also included slab stabilization and joint resealing to maintain structural integrity and prevent water ingress. The successful completion validated diamond grinding as an effective method for enhancing asphalt roadways.

An innovative application of a modified Next Generation Concrete Surface (NGCS) was tested in New South Wales, Australia. Developed by Australia's Roads and Maritime Services (RMS), this technique, Low Noise Diamond Grinding (LNDG), involves diamond grinding and diamond grooving to create a fine, corduroy-like surface finish using conventional equipment. The LNDG method shows noise reductions up to 3 dB(A) quieter than dense-graded asphalt, making it a cost-effective alternative to noise-reducing asphalt overlays.

The cost-effectiveness of diamond grinding for road maintenance in Phoenix, Arizona, projecting potential savings of $3.9 billion over 30 years. Diamond grinding was tested on various sections of SR 202 and Loop 101, in Phoenix, Arizona. In addition to a projected potential savings of $3.9 billion over 30 years, the technique delivered significant improvements in ride quality, noise reduction, and surface smoothness.

Three roadways were switched from asphalt to roller-compacted concrete. Diamond Grinding Roller-Compacted Concrete Pavement in Santa Fe Springs, California, highlights the use of diamond grinding to create a smooth, quiet surface on RCC pavements. The project involved replacing damaged asphalt on Greenstone Avenue and Sunshine Avenue, achieving a 25-plus-year pavement life.

Road owners increasingly see benefits of diamond grinding and grooving both new and existing asphalt pavements. Safety grooving, another diamond saw-cut surface texture, is being applied to asphalt pavement.
