The Highway Innovative Technology Evaluation Center (HITEC), a service center of the Civil Engineering Research Foundation (CERF), serves as a clearinghouse for implementing highway innovation by conducting nationally-focused, collaborative evaluations of new products and technologies. This report, Evaluation of the Tensar Mesa? Retaining Wall System, was prepared as part of the HITEC evaluation for earth retaining systems (ERS). This evaluation was performed on the Mesa? Retaining Wall System (Mesa System), a mechanically stabilized earth (MSE) structure developed, designed, and supplied by Tensar Earth Technologies, Inc. This report describes a HITEC evaluation designed to determine the basic capabilities and limitations of the Mesa System for use as a technically-viable dry cast modular block MSE retaining wall system when designed with coverage ratios of 71 and/or 100 percent. The evaluation was conducted based on material, design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The Mesa System features a modular block facing (MBW) of various configurations and high density polyethylene (HDPE) geogrid soil reinforcement, which are connected to the facing blocks with glass-reinforced polyethylene structural connectors.
