POROUS FRICTION COURSE SOLVES AIRPORT HYDROPLAING PROBLEM
Several hydroplaning incidents had occurred at the Greensboro-High Point-Winston Salem Regional Airport, N.C. Hydroplaning occurs when hydrostatic pressure builds up in the field of surface water under an aircraft's tire and reduces or eliminates tire-pavement contact when the aircraft is moving too fast for the pressure to be dissipated. As recommended for airfield pavements, the porous friction course (PFC) is a coarse, gap-graded asphaltic concrete mixture with a high, 80 to 88 percentage by weight of aggregate larger than a No. 8 sieve. The coarse surface texture provides surface flow plus pressure relief channels and pavement tire contact above a surface water film. Its high percentage of voids to total mix (25% to 45%) provides temporary storage for surface water and high permeability. Dispersing the added neoprene in the form of latex, the asphalt's performance is markedly improved. The overlay has been 100% successful in preventing hydroplaning accidents.
