Available in PDF, EPUB and Kindle. Book excerpt: Bare exposed weathering steel is an economical alternative to ordinary painted steel if the weathering steel develops a protective oxide coating, meaning that the bridge need not be painted during its service life. To ensure satisfactory corrosion performance, engineers should follow the guidelines for the use of weathering steel in bridges described in this paper.

This book was released on 2013 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weathering steel is commonly used as a cost-effective alternative for bridge superstructures, as the costs and environmental impacts associated with the maintenance/replacement of paint coatings are theoretically eliminated. The performance of weathering steel depends on the proper formation of a surface patina, which consists of a dense layer of corrosion product used to protect the steel from further atmospheric corrosion. The development of the weathering steel patina may be hindered by environmental factors such as humid environments, wetting/drying cycles, sheltering, exposure to de-icing chlorides, and design details that permit water to pond on steel surfaces. Weathering steel bridges constructed over or adjacent to other roadways could be subjected to sufficient salt spray that would impede the development of an adequate patina. Addressing areas of corrosion on a weathering steel bridge superstructure where a protective patina has not formed is often costly and negates the anticipated cost savings for this type of steel superstructure. Early detection of weathering steel corrosion is important to extending the service life of the bridge structure; however, written inspection procedures are not available for inspectors to evaluate the performance or quality of the patina. This project focused on the evaluation of weathering steel bridge structures, including possible methods to assess the quality of the weathering steel patina and to properly maintain the quality of the patina. The objectives of this project are summarized as follows: -- Identify weathering steel bridge structures that would be most vulnerable to chloride contamination, based on location, exposure, environment, and other factors. -- Identify locations on an individual weathering steel bridge structure that would be most susceptible to chloride contamination, such as below joints, splash/spray zones, and areas of ponding water or debris. -- Identify possible testing methods and/or inspection techniques for inspectors to evaluate the quality of the weathering steel patina at locations discussed above. -- Identify possible methods to measure and evaluate the level of chloride contamination at the locations discussed above. -- Evaluate the effectiveness of water washing on removing chlorides from the weathering steel patina. -- Develop a general prioritization for the washing of bridge structures based on the structure's location, environment, inspection observations, patina evaluation findings, and chloride test results.

Book excerpt: This report describes a 4-year bridge and test fence evaluation of protective coatings for maintaining weathering steel bridges. The test specimens consisted of steel panels cut from existing aged weathering steel bridges, along with some new mill scale bearing weathering steel as a control. The condition of the specimens ranged from extensively pitted and corroded (from chloride exposure) to mildly corroded and non-pitted. Specimens were cut from angle irons, stiffeners, cover plates, and web areas of bridges. Three methods of surface preparation were used: dry abrasive blasting, wet abrasive blasting, and power tool cleaning using rotary peening and non-woven abrasive discs.

Book excerpt: This report presents findings of a survey and laboratory evaluation of materials and techniques for cleaning and painting chloride-contaminated weathering steel bridges. Laboratory techniques suitable for field usage were developed for assessing the conductivity and chloride level of prepared surfaces. The following cleaning techniques were evaluated for their effectiveness in removing chloride from corroded and pitted plates: air abrasive wet blasting, dry blasting (including alternative abrasives), dry blast and rinse sequences, pressurized water jetting, power tool cleaning, hand tool cleaning, and chemical strippers. Eight coating systems, including organic and inorganic zinc, high-solids epoxies, thermal spray zinc, oil/alkyd, and petroleum wax were selected for laboratory evaluations. They were applied over laboratory and bridge specimens of weathering steel having various levels of chloride contamination using four preparation techniques: wet and dry blasting, power tool and hand tool cleaning. The coatings were exposed to salt spray, immersion in deionized water, and a composite test incorporating ultraviolet radiation, condensation, and freeze-thaw conditions. Based on these tests, and other considerations, the four surface preparation techniques and the following eight systems were selected for multisite 5-year bridge and test fence evaluation: epoxy zinc-rich, urethane zinc-rich, epoxy mastic, thermal spray zinc, three inorganic zincs (conventional and low-VOC ethyl silicate, and water-borne alkali silicate) and oil-alkyd control. Preliminary guidelines were developed for weathering steel maintenance options of no painting, painting corroded areas only, and painting entire structure.
