During the 1960s, NASA developed grooved runways to channel away water and improve traction for aircraft. By reducing the effects of hydroplaning, grooved runways minimize the chance of aircraft sliding off a wet runway during landing. This proved so successful that the technology has since been applied to highway design to improve safety. This section of concrete runway was used for testing by NASA's Langley Memorial Aeronautical Laboratory.
