JTRP Technical Reports
The term "quality" is defined as the conformance to predetermined requirements or specifications. These requirements may be set in terms of the end result required or as a detailed description of how work should be executed. Recently, there has been increasing interest in quality assurance in the construction industry. Quality assurance includes design and planning, sampling, inspection, testing, and assessment to ensure that end products perform according to specifications. This research proposes a new quality assessment model for highway steel bridges and more specifically for coating rust assessment. The research proposes a hybrid model using image processing and neural networks …

JTRP Technical Reports
The study identifies various painting systems that are successfully used in Indiana’s surrounding states and other industries. The identified systems are further screened and evaluated. After prudently comparing INDOT’s inorganic zinc / vinyl system with the waterborne acrylic system, the moisture cure urethane coating system, and the 3-coat system of zinc-epoxy-urethane, the results show that the new 3-coat system fulfills INDOT’s needs with the most benefits. Therefore, the 3-coat system is recommended to replace INDOT present inorganic zinc / vinyl system. To deal with the problems facing the lead-based paint, a comparison between full-removal and over-coating alternatives is made. Results …
