Repair and replacement of deteriorating piling systems cost the United States up to $1 billion per year. In the case of marine piling, actions required by the Clean Water Act rejuvenated many of the nation's waterways, but also allowed the return of marine borers, which attack timber piles. At the same time, less than 10% of the 13.7 million tons (122 GN) of plastic containers and packaging produced annually in the U.S. are recovered by recycling. Using recycled plastics to manufacture piles utilizes material which (1) would have been otherwise landfilled and (2) can be more economical in aggressive environments when life-cycle costs are considered. A series of polymer piles were driven in Elizabeth, New Jersey. Three concrete filled fiberglass shell piles, three polyethylene piles reinforced with steel bars, three polyethylene piles reinforced with fiberglass bars, and two solid polyethylene piles were installed. One closed end steel pipe pile was also driven for reference purposes. Three static load tests were performed on one of the concrete filled fiberglass shell piles, and one of each of the reinforced polyethylene piles. High strain dynamic pile tests were performed on all piles during initial driving and restrike after load testing. This study describes the adjustments to assumed material properties required during installation testing and the correlation between static and dynamic load tests. Copyright ASCE 2008.
