Description: "As part of Research Project 0-4829, a new testing device was developed and a monitoring program was initiated to evaluate the performance of geosynthetics used as reinforcement for unbound base courses. This implementation involves the use of the new testing device and procedures developed by the 0-4829 research project. Specifically, the testing involves a modified pullout device for characterization of the confined stiffness in geosynthetic reinforcements. The project also provides continued monitoring of 32 experimental test sections constructed on FM2 (Bryan District) for the purposes of correlating field performance with material characterization. The experimental component of this implementation project was accomplished by testing four different geosynthetic reinforcement products in order to verify the draft specifications recommended by project 0-4829. The field component of this implementation project involved continued condition survey, moisture monitoring, falling weight deflectometer (FWD) testing, and weather data gathering in order to establish the threshold of the proposed parameter in the new specification based on field performance."
