Laboratory Evaluation of Geocell Reinforcement Technology for Road Restoration

The authors performed physical model tests to investigate the reinforcement effect of geocell under moving wheel loads conditions. This is important to evaluate the internal stability of reinforced soil foundations. The relationship between the cyclic number of moving wheel loads, the wheel subsidence, and the foundation's deformation behavior was obtained from the series of tests. The deformation behavior was analyzed using the PIV technique on the cross-section pictures of the foundation. As a result, it was observed that the geocell-reinforcing technique could reduce wheel subsidence of the foundation. The PIV analysis indicated that the soil deformation in the inner geocell was confined. The authors have outlined this study's physical model tests and test results. Additionally, the results of the PIV analysis are shown, and the reinforcing mechanism of the geocell is discussed.
