The purpose of field monitoring system in KHC-Test Road is to provide the performance data for environmental loadings from pavement surface. Among them, water content reflectometer(WCR) are used for measuring the volumetric water content of pavement subgrades. However, WCRs are not well-calibrated based on the local field conditions. A need therefore exists for improving equations for predicting water content using the proper field and laboratory calibrations. Based on the study performed, calibrations based on various soil characteristics and density conditions are well fitted to the data from fields. So, it is recommended to use the suggested general calibration of WCR to the compacted subgrade soils in test road for predicting the volumetric water content.
