THE POTENTIAL OF POROUS FRICTION COURSES

A survey conducted by the Airport Operators Council International (AOCI) to gather data on grooved and porous friction course (PFC) treatment of runway surface is described. The AOCI survey has served to provide an operational assessment by airport operators of the effectiveness of PFC as an alternative to grooving to reduce hydroplaning at airport facilities. Based on average cost data received, grooving PCC was the most expensive technique and grooving of asphalt the least expensive. PFC costs were found to be between the two. The most commonly used groove configuration in the nation was one quarter inch by one-quarter inch by one and one-half inch. That configuration on PCC cost 50% more than the same configuration on asphaltic concrete. It was found that rubber deposits and other contaminants did not build up as quickly on grooved or PFC surfaces. Those airport authorities not treating their runways reported that it was either not needed, inadequate information, or too costly. The only poor performance has been reported in Nashville, Tenn. and the reason is not readily explained, although the performance of limestone aggregate in PFC has not been clarified. The report concludes that by following the design method, quality control procedures, and good construction practices recommended, PFC pavements can be constructed with a higher degree of confidence. The success of PFC in the Rocky Mountain Region using the larger-size aggregate with a more open-textured course suggests that design may be the key to rubber build up. High-pressure water blast with a rotating spray bar for removing rubber deposits also seems to have some potential.
