Chemical stabilization is widely used in geotechnical engineering to improve the engineering properties of geomaterials. The interaction between the stabilizers and soil particles changes the physicochemical structure of these materials and increases their performance. Water content and density are the indicators used in field practice for construction quality control of the stabilized soils. The nuclear method is currently the preferred technology for field measurement of water content and dry density in geotechnical engineering. However, the nuclear method has been found to give inaccurate results when used on stabilized soils. Researchers at Purdue University developed a procedure to measure soil water content and dry density using time domain reflectometry (TDR). Tests performed on conventional soils indicate that this procedure is accurate and fast. The feasibility of this technology on the stabilized soils was investigated; the preliminary conclusion was that TDR achieves satisfactory accuracy. In addition, the electrical properties measured by TDR are strong indicators of the physicochemical reactions taking place in the stabilized soils, which show that TDR technology can be a useful tool for monitoring these reactions.
