Interpretation of Event Response Through Web-Based Archival of TDR Signals

This project provides experimental assistance to Ohio Department of Transportation (ODOT). ODOT has requested that the Infrastructure Technology Institute (ITI) developed health monitoring technology be installed as the first phase of sealing shallow, abandoned coal mines to prevent sink hole development in the pavement of I70. Its simple installation process allows the project to begin this summer (thus quickly advancing the economic stimulus) and will improve the safety of a major interstate route. Thus, this project is responsive to two of Research and Innovative Technology Administration (RITA) Chief Administrator Appel's articulation of Department of Transportation (DOT) Secretary La Hood's four goals for USDOT: accelerate economic recovery, provide a sustainable mobility system, improve quality of life by fostering livable communities, and advance transportation safety. Matching funds for this project are those provided by Ohio DOT for the installation of the cables and ITI supplied instrumentation. See the last 7 pages of this proposal for the letter of agreement for interaction and in-kind match expenditure by Ohio DOT for the installation of the cables and  Time Domain Reflectometry (TDR) instruments. New funds are requested to further commercialize ITI developedTDR technology and the research developed internet data display technology. ITI will provide and evaluate the efficacy of a web-based signature database for TDR cables installed beneath I70 in an area of shallow coal mining. This work will involve display of TDR signatures over the internet for reference during normal operation as well as upon event notification. Event notification is supplied by GeoTDR. ITI will supply an archive of TDR signatures for comparison with that associated with the incident alarm. The project leverages ITI's past 8 years of experience operating a similar site for ODOT. This project supports three principal activities of ITI: (1) adoption by State DOT's of ITI developed technology, (2) display of ITI's national span of activity, and (3) proof of usefulness of ITI developed technology. A summary of past ITI sponsored TDR installations can be found at http://iti.northwestern.edu/publications/utc/FR-1-5-Dowding.pdf. TDR theory and applications can be found in the book GeoMeasurements by Pulsing TDR Cables and Probes, by O'Connor and Dowding (1999).
