Abstract:This report summarizes the work and results obtained from USDOT Cooperative Agreement No. RITARS-14-H-MTU, on remote sensing applications for geotechnical asset management. Considering the context of transportation asset management, a framework for the application or remote sensing tools is developed, particularly for monitoring geotechnical asset surface displacement, as part of the monitoring necessary for geotechnical asset management. A review of the transportation asset management paradigm is given in chapter 1, and the requirements for remote sensing based geotechnical asset management are explored in chapter 2. A survey on current practices, perceived needs and limitations gives an overview of the perspective of transportation agencies on this topic. Appropriate technologies are identified and selected for the tasks most relevant to geotechnical asset management, as explained in chapter 3. Field verification and evaluation of the remote sensing technologies is reported in chapter 4, always within the context of geotechnical asset monitoring. The monitoring of geotechnical assets has the goal of continuously or frequently assess the assets’ performance, according to the transportation management needs. Chapter 5 discusses asset performance definition and monitoring. Using the geotechnical asset condition information obtained from the monitoring requires some framework for decision making, the decision support system discussed in chapter 6 presents a web framework that contribute to this goal. Any implementation of new technology or methods requires and evaluation of its benefits, weighted against the costs of adopting such technologies, chapter 7 explores the costs of implementing remote sensing methods, and the value of the information that can be obtained from them. For transportation agencies to adopt the new technologies and implementation framework is necessary. Chapter 8 discusses the implementation framework for the remote sensing technologies tested in the project, giving also hypothetical examples on two of the field sites included in the project. The outreach components of the project are summarized in chapter 9, including the development of an outreach video and the multiple conference presentations and papers that were generated during the duration of the project.
