Abstract
The objective of the study is to verify a new calibration equation of dry density and water contents with TDR. Since the traditional calibration equation was proposed, some research to develop a new calibration equation has been conducted by several researchers. As traditional calibration equation is difficult to be applied for loose soil and fine-grained soil at high water contents, this study developed a new calibration equation. Thus, this study introduces a new calibration equation and its applicability by comparing TDR test results with conventional test results. Based on the analyses, the calibration equation for water content has large error. A new calibration equation was proposed and it showed more than 95% accuracy for estimating water content of soil.
