State Highway Agencies (SHAs) maintain Qualified Products Lists (QPLs) or Approved Materials Lists, which provide a means of approval for the use of selected products. These products can then be used in state and federally funded construction projects. Manufacturing companies who intend their products to be placed on QPLs apply for QPL inclusion processes required by SHAs. Often, approval processes include field evaluations and/or standardized tests. Standards-setting bodies such as the American Society of Testing and Materials (ASTM) and the American Association of State Highway and Transportation Officials (AASHTO) develop standardized tests. Approval processes and requirements differ across SHAs. The SHAs’ QPL approval processes likewise differ from each other.

This study focused on bringing all SHAs’ QPL inclusion processes and standard requirements pertaining to Erosion and Sediment Control Products (E&SCPs) to one more easily accessible location. The data collection process of this study thus included sending a survey to all SHAs; obtaining typical erosion and sediment control (E&SC) practices and QPL inclusion processes of all SHAs; obtaining standard test methods and requirements from SHAs’ specifications for highways and bridges; and obtaining testing equipment price estimates from manufacturing companies. 24 SHAs participated in this survey. The data of SHAs that did not participate in the survey were collected from SHAs' official websites. In overall, 50 SHAs and DCDOT QPL E&SCPs QPL inclusion processes were collected, included in the literature review, and used in analyzing inclusion processes. In this study, 109 standardized test methods and specifications pertained with E&SCPs were collected. Out of 109, 48 test methods were selected and summarized in the literature review, and their corresponding SHAs requirements were mentioned.

A catalog that consists of all SHAs’ QPL inclusion processes, requirements and standard specifications was developed online and the link is available in chapter-5. This study analyzed present SHAs’ QPL evaluation processes and developed recommendations to the most current evaluation processes.
