PFC‣PFC Asphalt-Rubber (A-R) is generallyrecommended to overlay concrete‣PFC-Performance Grade (PG) is typicallyrecommended for maximum water sprayreduction‣2.2 million tons of both types of PFCprojects between 2004 – July, 2010
PFC‣Expected life for both types of PFC is 10-14years, expected life for conventional overlay is 7years‣The cost for both PFCs is typically $20 to $30per ton higher than conventional overlay. Thiscost is offset by the longer expected life of PFCcompared to conventional overlaysType D HMAPFC A-RAfter 9 years: PFC A-Rin the Lufkin Districtshows minimal wear
