A new method is proposed for determining the volume of soil samples extracted for field density tests. The method consists of replacing the extracted soil with sand poured from a graduated cylinder and determining the volume of sand required to fill the hole. In a series of trials, the proposed new method was compared to the Test for Density of Soil in Place by the Sand-Cone Method (ASTM D 1556) and the Test for Density of Soil in Place by the Rubber-Balloon Method (ASTM D 2167). Results indicated that the proposed new method yields lower percentage errors and is less sensitive to edge and surface irregularieties in the sample holes. The new method is also simpler and faster to perform than the sand cone method.
