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.
