    Abstract

    The Clod test has been often used in the United States for obtaining the relationship between soil volume or volumetric strain and water content for expansive soils. Alternative encasement materials non-toxic to humans and non-hazardous to the environment were examined for the Clod test. It is shown that Elmer's craft glue is superior to the commonly used solution of Dow saran resin and methyl ethyl ketone (MEK) for its non-hazardous nature, low cost, and fast testing time. For several different expansive soils, nearly identical volumetric strain-water content curves were obtained using the traditional solution of Dow saran resin and MEK and Elmer's craft glue. 3M adhesive spray was shown to be not suitable for encasement material. It is concluded that Elmer's craft glue can be reliably used as an excellent alternative encasement material for the clod test.
