The highway innovative Technology Evaluation Center (HITEC) serves as a clearinghouse for implementing highway innovation by providing nationally focused, collaborative evaluations of new products and technologies. This report was prepared as part of the HITEC evaluation for this product.

Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes a HITEC evaluation of the Sight and Sound Screen System, manufactured by U.S. Gypsum Co., covering 11 performance issues. The Sight and Sound Screen (sold under the name of Ultrascreen) is a post-and-panel wall system designed to act as a sight and sound barrier for highways and as a privacy system for residential and commercial property owners. This report details the test procedures and analysis used to evaluate the system and provides the results. When the results are compared to the results presented in Guidelines for Evaluating the Performance of Highway Sound Barriers, the evaluating panel concluded that the Sight and Sound Screen meets or exceeds all of the applicable evaluation criteria. Prospective users should review these findings for applicability to their local conditions and standards.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. his report summarizes the results of an evaluation that was designed to test the performance of 11 seismic isolators and dampers. The devices were tested for stability, response during earthquake simulations, and fatigue and weathering effects.

Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the HITEC evaluation of a plastic stop sign manufactured by ALL SIGN Products, Inc. The evaluations of the ALL SIGN Polycarbonate Stop SignØinclude the results of a series of laboratoryØand field tests and an analytical evaluation.ØThe evaluation tested the product's retroreflectivity, color, and appearance under normal conditions and the effects of weathering and graffiti.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF/IIEC Innovation Center. This report describes a HITEC evaluation designed to determine the basic capabilities and limitations of the INTER-LOK System 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 INTER-LOK System features a cross-shaped, segmental precast concrete facing panel connected to metallic rebar and anchor plate type of soil reinforcement attached to the facing panels by a keyplate that interlocks with the facing panels.

Prepared by the Environmental Technology Evaluation Center (EvTEC), a service center of CERF/IIEC. This Technology Verification report describes the nature and scope of the environmental evaluation of the performance of the Plasma Enhanced Melter? (PEM?) system for waste treatment. The evaluation was conducted through a cooperative program established in 1998 between the Washington State Department of Ecology, Integrated Environmental Technology Inc., Allied Technology Group, and the Civil Engineering Research Foundation. The goal of this report is to provide potential users and purchasers of the PEM? system with information they need to make more informed decisions regarding the performance of PEM? as an equivalent or alternative to incineration for treating hazardous waste.
