ABSTRACT: The goal of the dissertation was to quantify the role of FRP in repairing corroded prestressed piles in a marine environment and to demonstrate the feasibility of using it for field repairs. Three laboratory studies and two field demonstration projects were undertaken to meet this goal. In the first study, corroded specimens were repaired under water and tests conducted to determine the extent of strength retained immediately after wrapping and after further accelerated corrosion. Results showed that the underwater wrap was effective in restoring and maintaining lost capacity in both situations. The second study attempted to determine the effectiveness of FRP for specimens where corrosion had initiated but with no visible signs of distress. In the study, 22 one-third scale model of prestressed piles fabricated with cast-in-chlorides were wrapped at 28 days and exposed to simulated tidal cycles outdoors for nearly three years. Two materials -- carbon and glass were evaluated and the number of layers varied from 1 to 4. Results of gravimteric tests showed that the metal loss in FRP wrapped specimens was about a quarter of that in identical unwrapped controls indicating its effectiveness in this application. The third study attempted to identify the most suitable pre-wrap repair. For this purpose, 26 scale model prestressed specimens were first corroded to a targeted metal loss of 25%, repaired and then exposed to simulated hot salt water tidal cycles for over two years. Two disparate types of repairs were evaluated -- an elaborate full repair and a simpler epoxy injection repair. Results of ultimate and gravimetric tests conducted at the end of the exposure showed that the performance of the full and epoxy injection repairs were comparable but vastly superior compared to identical unwrapped controls. Two field studies were conducted in which full-sized corroding piles were instrumented and wrapped to monitor post-wrap performance. Corrosion rate measurements indicated that rates were lower for wrapped piles compared to identical unwrapped piles. Overall, the study demonstrated that underwater wrapping of piles using FRP is viable and a potentially cost effective method of pile repair in a marine environment.

The purpose of this document is to identify and provide design guidelines for bridge scour and stream instability countermeasures that have been implemented by various State departments of transportation (DOTs) in the United States. Countermeasure experience, selection, and design guidance are consolidated from other FHWA publications in this document to support a comprehensive analysis of scour and stream instability problems and provide a range of solutions to those problems. The results of recently completed National Cooperative Highway Research Program (NCHRP) projects are incorporated in the design guidance, including: countermeasures to protect bridge piers and abutments from scour; riprap design criteria, specifications, and quality control, and environmentally sensitive channel and bank protection measures. Selected innovative countermeasure concepts and guidance derived from practice outside the United States are introduced. In addition, guidance for the preparation of Plans of Action ...

India's irrigated agriculture sector has been basic to India's economic development and poverty alleviation. One of India's major achievements is its rapid expansion of irrigation and drainage infrastructure. However, the major emphasis on development has been achieved at a cost. The importance put on new construction has diverted attention away from the need to ensure the quality, productivity, and sustainability of the services. Further, a governmental subsidy based approach has been used and this has resulted in irrigation and drainage services which, while enabling significantly higher productivity than from non-irrigated lands, are well below their potential. 'The Irrigation Sector' discusses directions for future growth, the framework for reform, and the reform agenda.

Marine Concrete Structures: Design, Durability and Performance comprehensively examines structures located in, under, or in close proximity to the sea. A major emphasis of the book is on the long-term performance of marine concrete structures that not only represent major infrastructure investment and provision, but are also required to operate with minimal maintenance. Chapters review the design, specification, construction, and operation of marine concrete structures, and examine their performance and durability in the marine environment. A number of case studies of significant marine concrete structures from around the world are included which help to reinforce the principles outlined in earlier chapters and provide useful background to these types of structures. The result is a thorough and up-to-date reference source that engineers, researchers, and postgraduate students in this field will find invaluable. Covers, in detail, the design, specification, construction, and operation of marine concrete structures Examines the properties and performance of concrete in the marine environment Provides case studies on significant marine concrete structures and durability-based design from around the world
