Abstract:
Time domain reflectometry (TDR) is a relatively new method for determining soil moisture content under road pavements from the measurement of the soil's dielectric permitivity. The purpose of this study is to evaluate the TDR method and equipment used for seasonal monitoring of soil moisture content. The study is based on data collected before and during the installation of instrumentation, as well as seasonal data collected over a period of three months in 1992 at a Strategic Highway Research Program test section in Boise, Idaho.
