Prepared by the Highway Innovative Technology Evaluation Center (HITEC).

This report describes a HITEC evaluation designed to determine the basic capabilities and limitations of the KeySystem II Retaining Wall for use as a technically viable, precast mechanically stabilized earth retaining wall system. The evaluation was conducted based on design, construction, performance, and quality assurance information outlined in the HITEC Protocol.?The KeySystem II Retaining Wall with TenCate XT geogrid reinforcement features modular block facing to which PET grid reinforcement is connected. The PVC-coated PET geogrid reinforcement is a high-strength, high-tenacity polyester yarn product produced by Tencate Geosynthetics.
