| Summary: | air volume relates to the change in water volume differs for changes in air volume and the changes in water volume during content changes over the depth of the active zone from local damage every year. These problems result from differential databases and soil properties prior to shrink or swell to decreasing, but the air volume change is limited by the during soil moisture changes is examined in this study. Equation for Moisture Induced Shrink and Swell (PREMISS). Evaluation of laboratory swell and shrinkage test results Evaluation of laboratory swell test results show that the Expansive soils are the cause of significant structural In developing the procedure for using PREMISS, two soil increasing, and the change in air volume is limited by the indicates that there is a linear relationship between the initial volume of air. During shrinkage, the air volume is initial volume of water. How these volume changes occur is the shrinkage form. The manner in which the change in measuring the swell limit of a soil is developed. In the predict the expected vertical movement beneath foundations. procedure is developed for using the Phase Relationship properties were investigated: the swell limit and the shrink and swell. During swell, the air volume is shrink and swell. This linear relationship is consistent shrinkage limit investigation, the Submersion Method shrinkage limit measured by current ASTM Methods. There are shrinkage limit test is proposed. This method measures the shrinkage limit. These limits are the soil moisture contents swell limit probably does exist, and a procedure for that correspond with extreme volumetric conditions. the continuity between the changes in air and water volumes The equation is based on soil weight-volume relationships and two forms of PREMISS. One is the swell form, and the other undisturbed shrinkage limit as opposed to the remolded volumetric changes in the soil structure. In this study, a with PREMISS. within the soil. This equation uses seasonal soil moisture |
