Evaluation of Galvanized and Painted - Galvanized Steel Piling - TR-766
| 项目名称： | Evaluation of Galvanized and Painted - Galvanized Steel Piling - TR-766 |
| 摘要： | The primary objective of this research is to evaluate the effectiveness of galvanized and painted-galvanized piles at extending bridge service life in a cost-effective manner. This will be achieved through a systematic laboratory and field investigation, coupled with a Monte Carlo simulation of life-cycle costs. This project will begin with a comprehensive literature search which will supplement the knowledge and experience of the research team in working with substructure components. In the laboratory, a series of pile sections will be evaluated via an accelerated corrosion testing protocol. During this testing, various types of piles and coating systems will be evaluated � including traditional bare, steel piles. This testing will provide side-by-side performance data as well as valuable inputs for the life-cycle cost analysis. In addition, a unique opportunity exists to evaluate the in-place performance of a bridge constructed using galvanized steel components. The performance of this bridge will be evaluated for its long-term corrosion resistance performance. A comprehensive service life analysis will then be performed to understand the costs and benefits associated with using substructure coatings. This will be an important step in making the decision to implement the investigated coatings on a broader scale. To achieve the objectives of this project, several tasks are proposed. The tasks will be performed in very close communication with a Technical Advisory Committee (TAC) throughout the duration of the project. To this end, the research team plans to hold quarterly meetings with the TAC to update them on progress and to ensure that the research direction is as desired. Tasks include: Task 1. Comprehensive Literature Review; Task 2. Laboratory Investigation; Task 3. Field Investigation; Task 4. Life Cycle Analysis; Task 5. Final Report. |
