Synthesis of Concrete Bridge Piles Prestressed with CFRP Systems

The transportation infrastructure is aging and deteriorating mostly due to corrosion problems related to the prestressing steel strands. A corrosion-free material for reinforcement will create alternatives for bridge engineers to design long-lasting and safer bridge members. If not considered, corrosion will create additional maintenance and replacement costs for Texas Department of Transportation (TxDOT). Furthermore, the loss of cross-section of the prestressing steel will result in lower load carrying capacity of the member, which may eventually lead to structural failure. This will cause a public safety issue. Prestressed concrete piles are exposed to aggressive environmental affects that cause corrosion of the internal prestressing steel. The loss of functionality due to corrosion of the prestressed reinforcement of the piles causes service interruptions or replacements and in most cases requires expensive interventions. A promising alternative to prestressing steel is the use of corrosion-free carbon fiber reinforced polymer (CFRP) prestressing strands in prestressed concrete piles. The behavior of the CFRP prestressed concrete piles should be investigated as a possible component of bridges with much longer target design lives (exceeding 100 years). Current investigations indicate that some departments of transportation (DOTs) are including pilot studies using CFRP in the design of prestressed piles. Most of these studies are not assessed through laboratory tests. Furthermore, there is a lack of design specifications and construction procedures to enable transportation engineers to adopt this innovative technology. As part of this synthesis study, the research team shall: (1) Conduct a comprehensive literature review of all existing, published and unpublished, investigations related to CFRP prestressed piles. (2) Identify the research and practice gaps. (3) Derive a research plan including experimental and analytical studies to complement existing knowledge. (4) Identify the set of design guidelines and construction specifications that needs to be developed for the use of these materials. The synthesis study shall develop a plan for the required research and implementation plans to be adopted by TxDOT.
