Mechanically Stabilized Earth (MSE) walls have provided an effective solution to constructing retaining walls. The engineering and construction industry is continually striving to provide more cost-effective and design-efficient means to building MSE walls. Hilfiker Retaining Walls has developed a new semi-extensible metal mat reinforcement technology which does not fit into the current extensible or inextensible categories as defined by regulating authorities. The objective of this project was to construct and observe the behavior collect quantitative data for a 20-foot tall MSE wall using the prototype semi-extensible reinforcement technology. The results were compared to expected American Association of State Highway and Transportation Officials Load Reduction Factored Design values and was also compared to another case study, Prediction of Reinforcement Loads in Reinforced Soil Walls as conducted by Tony M. Allen, P.E., and Richard J. Bathurst, Ph. D., P. Eng. Comparing the behavior of the 20-foot prototype MSE wall to these design regulations and case studies allowed for proper classification and will facilitate future industry design efforts.
