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 waterproof and protect these gages in a field environment is critical. The survivability of a method used to attach and waterproof the foil strain gages was successfully demonstrated in the field and is described herein.
