Federal Highway AdministrationUS Transportation CollectionA study to evaluate the production and field performance of marine piling fabricated with improved structural materials is currently being performed by the Oregon State Highway Division under the sponsorship of the Federal Highway Administration. In this study, materials that were developed mainly for bridge deck protection and rehabilitation were used in fabricating precast prestressed concrete piling. During this project, 23 test piles measuring 12''X 12'' X 65' long were fabricated and placed in a dolphin for pier protection in Yaquina Bay at Newport, Oregon.The special materials incorporated into the study included polymer concrete, polymer impregnated concrete, latex modified concrete, and internally sealed concrete. Five piles were fabricated using each system. In addition, six miniature piles measuring 8'' X 8'' X 20' containing epoxy coated reinforcing steel bars were constructed and attached to three conventional precast prestressed concrete piles.75
