Abstract

Since the advent of turbojet operations at airports, the Federal Aviation Administration (FAA) has been involved through research and experience to improve the construction standards of pavements. This includes the pavements structural capacity as well as its surface integrity for effective braking action. To improve on the latter, FAA has promoted grooving as one of the highest priorities to be considered for improving braking friction and mitigating hydroplaning. Today, almost 100 runways in the U.S. are grooved. Another improvement developed through research and experience is a porous friction curse overlay. There are some 30 runways constructed with this type overlay. In addition a task group within FAA has prepared a list of some 200 runways which are potential candidates for grooving.
