This paper describes a practical heave prediction procedure that utilizes resin-coated samples (the CLOD test) to characterize expansive soil properties. The primary advantages of the CLOD test are its simplicity and its suitability for testing hard, fractured soils that are difficult to test in oedometers. Two field study areas having diverse geologies, climates, and soil types are used to assess the prediction method. Results to date indicate good agreement between predicted and actual heave for one site which has a homogeneous soil profile. The method overpredicts heave at the other site which has dipping bedding planes. (A) For the covering abstract see IRRD 881647.
