Book Description
"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.

Book Description
Corrosion, Volume 2: Corrosion Control deals with corrosion and corrosion control. Topics covered range from the design and economic aspects of corrosion to cathodic and anodic protection; pretreatment and design for metal finishing; protective action of metallic coatings; and methods of applying metallic coatings. Corrosion testing, monitoring, and inspection are also considered. This volume is comprised of 13 chapters; the first of which provides an overview of corrosion control, with emphasis on the classification of practical methods of corrosion control. Attention then turns to the economic aspects of corrosion; how corrosion control is implemented in chemical and petrochemical plants; and design considerations to prevent corrosion in buildings and structures. Design in marine engineering and in relation to welding and joining is also discussed. The chapters that follow focus on the principles and practical applications of cathodic and anodic protection; chemical and mechanical pretreatments for metal finishing; and design for corrosion protection by electroplated and paint coatings. Chemical conversion coatings and miscellaneous coatings such as vitreous enamel coatings are also considered. Finally, this book describes the conditioning of the atmosphere to reduce corrosion. Tables and specifications as well as terms and abbreviations are included. This book will be of value to students as well as workers and engineers involved in corrosion and corrosion control.
