Diamond Grinding Improves Smoothness on Illinois Bridge deck by 76-79%
To enhance the smoothness and overall driving experience on bridge decks, the Illinois Department of Transportation (IDOT) implemented a new policy on diamond grinding overlays. The U.S. 30 bridge project significant improved smoothness and resulted in a quieter deck due to the transition from transverse to longitudinal grooving and overall reduction of surface roughness.
