Airports around the world are experiencing an increase in airtraffic making landings an obvious focus for safety improvements. Since the 1960s grooving of runways and high-speed taxiways is one way that airports have aimed to improve safety in their key heavy-traffic areas.
On a wet, grooved runway aircraft stopping-distance is decreased by 35%. Runway grooving is an obvious consideration when making safety improvements at any airport. Grooving consists of diamond-cutting small grooves into the existing runway surface. Just 6mm deep by 6mm wide, with a spacing of 38mm centre to centre, this method greatly reduces hydroplaning on landings and take-offs.
In addition to the safety benefits, grooving can reduce issues of liability for the airport and has demonstrated cost savings. Application of de-icing materials will be reduced once a runway is grooved.
