Available in PDF, EPUB and Kindle. Book excerpt: The recently promulgated environmental regulations concerning volatile organic compounds (VOC) and certain hazardous heavy metals have had a great impact on the bridge painting industry. As a response to these regulations, many of the major coating manufacturers now offer "environmentally acceptable" alternative coating systems to replace those traditionally used on bridge structures. The Federal Highway Administration sponsored a 7-year study to determine the relative corrosion control performance of these newly available coating systems. The most promising coating systems were selected for long-term field evaluation based on accelerated test performance. The long-term exposure testing was conducted for 5 years in three marine locations. Panels were exposed on two bridges, one in New Jersey and one in southern Louisiana. The third long-term exposure location was in Sea Isle City, New Jersey. Thirteen coating systems were included for long-term exposure testing.

This book was released on 1998 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to state department of transportation (DOT) bridge maintenance engineers, coating specialists, chemists, and researchers. Manufacturers and suppliers of corrosion protection products and systems for exposed structural steel on existing bridges will also find it of interest. This synthesis describes current practice regarding maintenance and protection strategies for exposed structural steel on existing bridges. NCHRP Synthesis 251, Lead-Based Paint Removal for Steel Highway Bridges ( 1997), provides a complementary and more in-depth treatment of maintenance issues involving lead-based paint removal. This report of the Transportation Research Board defines the maintenance management systems and decision making criteria used by transportation agencies for maintaining exposed bridge steel. Material selection criteria, surface preparation and application practices, quality control and quality assurance programs, and funding mechanisms are discussed in detail. The impact of recent and proposed environmental and worker protection regulations on current practice is reported. Information for the synthesis was collected by surveying state transportation agencies and by conducting a literature search. Responses to the survey, Appendix C to this document, are published on the Internet as NCHRP Web Document 11.

This book was released on 1992 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recently promulgated environmental regulations concerning volatile organic compounds (VOCs) and certain hazardous heavy metals have had a large impact on the bridge painting industry. As a response to these regulations, many of the major coating manufacturers have begun to offer "environmentally acceptable" alternative coating systems to replace those traditionally used on bridge structures. In the interest of determining the relative corrosion control performance of these newly available coating systems, the Federal Highway Administration contracted for a seven-year study. As a precursor to long-term, natural exposure testing of various environmentally acceptable coating systems, a battery of accelerated laboratory screening tests were performed. These tests included 13 high solids or waterborne, conventionally applied coatings; 14 powder coating or metallized coatings; and 7 high VOC control coatings. These systems were tested in a cyclic salt fog/natural marine exposure, a cyclic brine immersion/natural marine exposure, and a natural marine exposure. Adhesion and water penetration tests were also performed on each system.

Book Synopsis Durability of Steel Bridge Corrosion Protection Systems Using Field Data and Laboratory Testing by : Julie Giannino
Download or read book Durability of Steel Bridge Corrosion Protection Systems Using Field Data and Laboratory Testing written by Julie Giannino and published by . This book was released on 2022 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion is the greatest problem facing steel bridges today. Corrosion is caused by the interaction of steel and atmospheric conditions. It can be prevented by adding a protective layer to the steel or by using a protective steel, collectively known as corrosion protection systems. The purpose of this study is to evaluate the performance of six of the most common corrosion protection systems: uncoated weathering steel (UWS), uncoated stainless steel, galvanizing, metallizing, 1-coat inorganic zinc paint, and a 3-coat organic zinc paint system, in relatively corrosive environments. The severely corrosive environments considered in this research are coastal environments where natural chlorides are present and environments where chlorides are present via the high use of deicing salts. Performance was evaluated first through a statistical analysis of existing field data and subsequently through implementation of laboratory accelerated corrosion testing on each of the corrosion protection systems for 80 cycles, representing 80 years in the field. The statistical analysis of field data showed the relative ranking in order of descending performance to be: galvanizing, UWS, then paint, with metallizing having variable performance over different age ranges; this ranking was affirmed by longevity estimates determined through laboratory testing when lower, more conservative percent mass loss and percent rusted benchmarks were used to determine the longevity estimates. Stainless steel corroded more than expected during laboratory testing and requires further investigation. The implications of the longevity estimates show that steel can provide a long service life even in a relatively severe environment. Use of any of these corrosion protection systems can improve performance, increase service life, decrease required maintenance, and provide economical steel bridges.

Book Synopsis Protective Coatings for Bridge Steel by : Clive H. Hare
Download or read book Protective Coatings for Bridge Steel written by Clive H. Hare and published by Transportation Research Board National Research. This book was released on 1987 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to bridge designers, materials engineers, maintenance engineers, and others concerned with coating systems used to protect bridge steel from corrosion. Information is presented on the causes of steel corrosion and the types of surface preparation and coatings used to protect the steel. Steel bridges need some type of protective coating to keep them from corroding. This report of the Transportation Research Board explains the mechanisms of steel corrosion and how coatings protect the steel, discusses the need for and types of surface preparation, and describes twenty types of available coating systems under three general categories: inhibitive systems, zinc-rich (sacrificial) systems, and barrier systems.

Download or read book Structural Steel Coatings for Corrosion Mitigation written by John Joseph Myers and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Task 1 of this project was to survey the performance of coating systems for steel bridges in Missouri and to evaluate coating and recoating practices. Task 1 was led under the direction of Dr. Glenn Washer from the University of Missouri located in Columbia, MO. A specific literature review focused on current state-of-the-practice for overcoatings, bridge coating assessment and rating, deterioration rate modeling as well as the risk assessment for overcoating. A new coating evaluation guideline was created to meet the needs of bridge maintenance in Missouri. Finally a field survey was carried out onto the existing bridge coatings across 10 Missouri Department of Transportation (MoDOT) districts and 26 counties. It was found that system S and G perform very well in many of the situations observed. The survey indicated that in many cases system S overcoatings are providing service life extension for the coating system, with some early failures resulting from severe exposure to deck drainage and corrosion. Deck condition, drainage, and joint conditions were found to be the dominate factor in deterioration of the coating system, regardless of the age of the coating. Task 2 of this project investigated the performance of new types of coating technologies on bridge corrosion mitigation and was led under the direction of Dr. John Myers from the Missouri University of Science and Technology located in Rolla, MO. Twelve coating systems including MoDOT system G were evaluated through several laboratory tests to study and predict the field performance and durability of new coating technologies. The new coating systems investigated in this study involved polyurea, polyaspartic polyurea, polysiloxane polymers and fluoropolymer. To date, these coating system technologies have not been used as a steel structural coatings system in the State of Missouri by MoDOT. The laboratory tests consist of freeze-thaw stability, salt fog resistance, QUV weathering and electrochemical tests. The comparison study was carried out to benchmark and understand the pros and cons of these new coating systems. In addition, two coating systems served as overcoating studies for lead-based paint systems representative of older existing bridges in the state of Missouri. These overcoating systems were evaluated using an accelerated lab test method and electrochemical test. The performance of the existing MoDOT calcium sulfonate (CSA) overcoating system (system S) was also studied within the test matrix for comparative purposes. The test results show that moisture cured urethane micaceous iron oxide zinc/polyurea polyaspartic is a promising coating system for recoating of new steel bridges and that aliphatic polyaspartic polyurea can also be applied on existing coatings after the surface is properly prepared"--Technical report documentation page.
