Status of runway slipperiness research

Runway slipperiness research performed in the United States and Europe since 1968 has been reviewed. This review suggests the following benefits to the aviation community: Better understanding of the hydroplaning phenomena; a method for predicting aircraft tire performance on wet runways from a ground-vehicle braking test; runway rubber deposits identified as a serious threat to aircraft operational safety; methods developed for removing rubber deposits and restoring runway traction to uncontaminated surface levels; and developed antihydroplaning runway surfaces, such as pavement grooving and porous friction course, which considerably reduce the possibility of encountering aircraft hydroplaning during landings in rainstorms. /Author/
