Effectiveness of Geosynthetics in Soil/Aggregate Stabilization—Evaluation Using Bender Element Sensor Technology

项目名称：	Effectiveness of Geosynthetics in Soil/Aggregate Stabilization—Evaluation Using Bender Element Sensor Technology
摘要：	Geosynthetics, particularly geogrids (and to a lesser extent geotextiles), perform the function of “mechanical” stabilization in unpaved and paved road soil/aggregate layers. The primary objective of this research is to evaluate the effectiveness of available geosynthetic products in pavement soft subgrade and base/subbase stabilization applications and to develop design guidelines for Illinois Department of Transportation (IDOT) based on the most relevant local stiffness increase mechanism. To achieve this goal, bender element sensor technology based on the small strain shear wave measurement technique will be used to quantify the local stiffness increase by the best match of geosynthetic-aggregate composite and to investigate factors governing the degree of geosynthetic-aggregate interaction through laboratory triaxial specimens and large-scale box tests. Results from this project will be used to develop design guidelines for the use of geosynthetics in stabilization applications of soil/aggregate layers.
