Abstract:

A comprehensive instrumentation system was installed at four sites across the state of Tennessee to monitor long-term seasonal changes in subgrade water content. This paper summarizes the instrumentation and evaluates each of the monitoring methods. The instrumentation included a complete weather station, time domain reflectometry probes, temperature sensors in the pavement and subgrade, free-drainage pan lysimeters, and resistivity probes. The paper describes problems encountered, how they were resolved, the value of the data obtained, and provides recommendations based on the lessons learned from the 5-years of data collection.
