Research, Design and Validation of NPA Tough-Cells in the Field

Dr. Pokharel is a leading expert in the application of the geosynthetic reinforcement especially, NPA Tough-Cell technology. Findings from his years of research at U. of Kansas are used to design sustainable Geocell-reinforced structures. His recent published research has focused on validating Neoloy Tough-Cell design and performance in the field, particularly on road pavements in Canada, as well as quantifying the contribution of NPA Tough-Cells to sustainable roads.
