Safety Grooving: Grooving enhances traction and safety on the Dan Ryan Expressway in Chicago, Illinois

The Dan Ryan expressway, which runs through the south side of Chicago and is one of the most heavily traveled roads and finally saw extensive reconstruction in the 2000s. Diamond grooving the existing concrete represented an economical choice compared to other treatments, with a total project cost of $330,550. Despite challenging conditions—lane widths for the project varied, work was performed at night and traffic control efforts were demanding—work was completed in 30 working days.

Safety Grooving: ODOT uses longitudinal grooving for safety on asphalt as well as concrete pavements

The superior safety performance of grooving on bridge decks encouraged the ODOT to use the technique on several sections of asphalt pavement, all located on high-speed roadways and tight curves where wet weather safety was a concern. Diamond grooving on three Ohio highways (SR 126 in Hamilton County, I-90 in Cuyahoga County and I-75 Montgomery county) significantly reduced wet-weather accident rates.

Safety Grooving for Safer Runways: Runway rehabilitation at Dyess Air Force Base

Keeping America's air defense ready and flying safely has always been a national priority. Such was the case for a repair project in the summer of 2001 at Dyess Air Force Base located outside of Abilene, Texas. A very aggressive two-week runway closure was negotiated with the Air Force to complete the diamond grinding and grooving of the 125,000-square-yard main concrete runway. The Air Force was thrilled with the timeliness of the work and the quality of the final product.

Safety Grooving for Safer Runways: Runway 9L - 27R, Fort Lauderdale, FL

Fort Lauderdale Hollywood International Airport (FLHIA) located in Broward County, FL, was experiencing distress and lost friction on their runway. Airport engineer recommended diamond grinding and grooving as a solution to the problem. The scope of work included patching areas of deteriorated pavement, diamond grinding approximately 110,000 square yards of asphalt runway deep enough to remove the existing grooves, re-grooving the runway in accordance with standard Federal Aviation Administration (FAA) specifications.

Safety Grooving for Safer Runways: Ottawa International Airport, Ottawa, Canada

The Ottawa International Airport (OIAA) in Canada was experiencing runway skidding incidents. Wet pavement conditions were considered to be a major contributing factor. Diamond grooving was added to the pavement for the entire length of the runway.

Five Airports in Canada Adopt Runway Grooving to Reduce Hydroplaning

Diamond grinding and grooving airport runways is common in the United States; Canada has made limited use of the technique. This is changing, due to overwhelming evidence that diamond grooving is a proven strategy for reducing the risk of hydroplaning and improving runway safety. Grooving works by providing channels for water to escape, helping eliminate standing water and restoring tire friction coefficients on wet pavement.
