Subgrade Moisture Variations. Interim Report Vii: Subgrade Temperature Measurement
Subgrade moisture conditions at several field sites could not be related to precipitation, and were thought to be temperature-dependent. Accordingly, subsurface thermistor probes were installed at six sites, to measure subgrade temperature gradients and relate them to subgrade moisture conditions. The report reviews previous work in thermal moisture flow and subgrade temperature measurement by other agencies, then describes instrumentation and procedures for measurement of subgrade temperatures under existing highway pavements, and gives procedures for data collection and evaluation. Results of the research show that temperature gradients caused measurable subgrade moisture migration, but, in Oklahoma subgrades, temperature-induced moisture variation appears to be of secondary nature, when compared to moisture variation caused by other factors, such as precipitation.
