MEASUREMENTS BENEATH THE SURFACE OF EXPANSIVE CLAY

Several methods for predicting moisture movement and potential heave of expansive soils are available. In June 1973, a field experiment was initiated because a dearth of integrated field data precluded evaluation of these predictive methods. Various methods were developed and used to measure changes in density, water content, and soil suction in relation to surface and subsurface heave at depths to 15 ft (4.6 m) below an expansive clay surface. This paper describes the methods used, method of installation, and preliminary results.
