Grooving airport runways is common practice in the United States. The U.S. Federal Aviation Administration (FAA) recommends grooving for all airport projects funded with federal grants, which represents most projects.
Similarly, U.S. Department of Defense facilities are increasingly specifying new, reconstructed or resurfaced runways to be grooved. In Canada, however, there has been limited use of runway grooving. In recent years this situation has been changing, due to the overwhelming evidence that grooving is a proven strategy for reducing the risk of hydroplaning and improving runway safety.
