Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Bridge and Foundation Engineering Team
Roadmap/Focus area(s):	Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:	This project is collection of five separate tasks with a common focus on the collection of data for performance management of walls, slopes, and nonbridge, nonpavement assets.
Laboratories:	Geotechnical Laboratory
Start Date:	October 1, 2011
End Date:	December 31, 2014
Funding Amount:	$0.00
FHWA Program Name:	IRT (Infrastructure Research and Technology)
Goals:	(1) Wall and Slope Management Best Practices: Capture lessons learned from the Federal Lands/National Park Service inventory program with respect to measuring and identifying functional and condition assessment of retaining walls, and how these data can be analyzed through time. (2) Synthesis on Real-Time Automated Geotechnical Data Collection Systems: Investigate the current products available for real-time monitoring of geotechnical structures and develop a report that provides a general overview of automated data collection systems for geotechnical applications and comprehensive guidelines for designing these systems for remote monitoring of the engineering performance of new and existing structures in real time. (3) Exploration of Innovative Lateral Deformation Monitoring Technologies: A review of current practices and systems currently available and installed on existing geotechnical structures for case history assessment will be performed. Microelectromechanical systems (MEMS) technology will be evaluated for accuracy, resolution, sensitivity, linearity, noise, and error in a controlled, laboratory setting. (4) Advanced Geotechnical Instrumentation for Measurement of Lateral Earth Pressure: Review existing methods to measure lateral earth pressure and evaluate the use of new instrumentation (i.e. tactile pressure sensors). Test pressure sensors in the laboratory and identify methods to make the sensors more durable for field applications.
