The purpose of this study was to develop procedures for simple and rapid determination of frost susceptibility of granular materials used for base courses. Methods were employed using laboratory freezing tests and correlation with physical characteristics obtained from routine engineering tests of the materials. A freezing procedure has been developed using a Peltier battery for the heat sink, cylindrical specimens in a ring type mold and a continuous supply of water to the specimen, and determining rate of heave of the specimen during freezing. Preparation and freezing of a specimen can be accomplished in approximately 48 hours. Data are presented to indicate the variation of heave rate of materials depending on grain size distribution and void ratio. BPR abstract
