Although the relative density is an important factor showing mechanical properties of granular soils, the methods for its estimation have not been satisfactorily standardized. Many researchers have proposed various methods to determine max, and min, dry density, but the results, especially for max, dry density, show significant differences. In this study, a simple and practical method of evaluating the max, relative density was proposed, which could give reliable results in comparison with conventional methods. The experiment was carried out by varying the number of blows and the layers of the sample for each mold and the results were compared with those of Bowles method.
