Foil Strain Gage Attachment Techniques for Geotextile and Geogrid

Seventeen full-scale test sections were constructed on a low-volume, flexible pavement. The test sections were reinforced with geotextiles and geogrid, instrumented with Micro-Measurement Group foil strain gages. While strain gage attachment to rigid materials is well understood, methods used to attach foil strain gages to geotextiles, specifically, are more challenging due to the matrix of fibers in the material, and the method used to...
