| A laboratory research study conducted at The University of Texas at Arlington proposed the use of four novel stabilizers to stabilize soft expansive soils of Southeast Arlington. A field monitoring study is needed to validate the effectiveness of these stabilizers in the field conditions. Such field studies will provide better understanding of stabilizers when they are exposed to variations in temperature, humidity and various external disturbances.; In order to compare the stabilizing effects and hence forth to develop specifications for their usage, an instrumentation system was designed and procured. Preliminary calibration methods adopted to scale these gages are discussed. Laboratory investigations on large-scale soil setup were conducted to verify reading obtained from these gages. These results are compared with theoretical calculations. Comparisons showed that sensor measurements are repeatable and reliable. Measurements in both static and dynamic loading conditions matched quite well with theoretical predictions.; Recommendations and cautions for field installation have been developed and documented. These need to be followed for reducing the installation problems expected in the field. |
