Student Involvement | A graduate research assistant will be supported 1/2 time for conducting research on the subject project. | ||||||||
Project Objective | To determine the most cost-effective coating system for structural steel bridges in Missouri by evaluating the past performance of coatings, and testing the performance of new coatings. | ||||||||
Project Abstract | Task 1: Evaluation of Coating System Performance in Missouri Task 1 of the proposed research consists of a field evaluation of the existing coating systems in Missouri to determine the past and current performance of coating systems utilized in the State. The steel coating systems and procedures being utilized by other State DOTs will be evaluated with respect to current practices to identify areas to be examined for enhancing current practices and potential cost impacts. A consistent and quantitative method for characterizing the condition and performance of a coating in place would be defined based on experience in other States, standards and needs such that a systematic study of coating performance in Missouri can be conducted. The field performance survey will document and correlate factors such as environment, location and extent of coating failure/corrosion, surface preparation procedures, etc. | ||||||||
