The Airport Operators International survey has provided an operational assessment of the effectiveness of the porous friction course as an alternative to grooving to reduce hydroplaning at airport facilities. Airport operators that have applied porous friction courses are pleased with their performances, both as to friction characteristics and wearability. The Federal Aviation Administration has evaluated these courses for airport pavements and presented data on their design, construction, and performance. This technical evaluation essentially supports the consensus of the operational survey that performance has been good. On the assumption that asphalt concrete grooving and porous friction courses are equally effective, airport operators are encouraged to explore the cost of each in their geographic areas to determine which is less costly. If the aggregates necessary to meet specification requirements must be hauled in, grooving may be the better choice. In the airport operators' opinion, design specifications and acceptable cleaning methods have not been fully explored. The success of porous friction courses that use larger size aggregates with a more open textured course suggests that design may be the key to rubber buildup. The use of a high-pressure water blast with a rotating spray bar for removing rubber deposits seems to have potential. /Author/
