    A model is suggested to predict heave of expansive shale formation based on soil suction change. The model satisfactorily described the field volume change where the anticipated heave is compared with direct measurement obtained from an instrumented field station. The prediction is further simplified by introducing a model that only uses the moisture content variation to determine the amount of heave. Close agreement is observed between measured and model-predicted shale behavior. Application of this simplified model eliminates the difficulty of recovering an undisturbed specimen of shale which is highly weathered and friable as well as laminated.
