Summary of Highway Product Evaluation Practices and HITEC Needs Survey
Contains the results from a survey conducted by the Civil Engineering Research Foundation (CERF), the research affiliate of the American Society of Civil Engineers. This report provides a summary of product evaluation activities, and policy/technical guidance to plan and operate Highway Innovative Technology Evaluation Center (HITEC).
Bioremediation in the Highway Environment
Prepared by the Environmental Technology Evaluation Center (EvTEC) and the Highway Innovative Technology Evaluation Center (HITEC), CERF Service Centers. This report provides an update on technology and is intended to assist the Federal Highway Administration's Priority Technology Program (PTP) and departments of transportation in all 50 states. It identifies barriers that hinder the widespread use of bioremediation in the highway environment, as well as methods to overcome these barriers. The evaluation is based on design, construction, performance, and quality assurance information outlined in the HITEC and EvTEC Protocols. The three case studies examine PTP projects in Alabama, Indiana, and Mississippi.
Summary of Evaluation Findings for the Testing of Seismic Isolation and Energy Dissipating Devices
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.
Guidelines for Evaluating the Performance of Highway Sound Barriers
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report presents the HITEC evaluation plan for U.S. Gypsum's Sight and Sound Screen. The Sight and Sound Screen 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. The HITEC evaluation will measure the performance of the barrier against the criteria presented in this report, which reflect the needs of the highway community. Although this evaluation plan was tailored to one product, as a service to state and local transportation officials the report was expanded to provide guidelines that can be adapted for use with other types of sound wall systems.
Evaluation of the Tensar ARES Retaining Wall System
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report evaluates the ARES Retaining Wall System, manufactured by Tensar Earth Technologies, Inc., to determine its basic capabilities and limitations for use as a technically viable, precast, mechanically stabilized earth structure. The evaluation was conducted based on design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The ARES System features segmental precast concrete facing panels five feet high by nine feet wide (1.52 mØby 2.74 m) and high-density polyethylene geogrid soil reinforcement, which is connected to the facing panels using a newly developed slot connection method.
Evaluation Findings for Earthquake Protection Systems, Inc. Friction Pendulum Bearings
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report summarizes the results of a detailedØevaluation of Friction Pendulum Bearings,Ømanufactured by Earthquake Protection Systems, Inc. The report is part of a program to test the performance of 11 seismic isolators and dampers produced by several manufacturers. The devicesØwere tested for stability, response during earthquake simulations, and fatigue and weathering effects.
Preliminary Evaluation Findings for Ice Ban
Prepared by the Highway Innovative Technology Evaluation Center, a CERF Service Center. This report describes results obtained from the field evaluation of Ice Ban as a liquid anti-icing and deicing agent during the 1996-1997 winter season. Ice Ban is the concentrated liquid residue of the fermentation and distillation of alcohols (ethanol) and the processing of corn and other agricultural products. Ice Ban can be applied as a liquid anti-icing or deicing agent and as a road salt or sand pretreating agent.
Evaluation of the SSL MSE Plus Retaining Wall System
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF service center. This report describes a HITEC evaluation designed to determine the basic capabilities and limitations of the MSE Plus System, manufactured by SSL, LLC, for use as a mechanically stabilized earth retaining system. The evaluation was conducted based on material, design, construction, performance, and quality assurance information outlined in the HITEC Protocol. TheØMSE PlusØSystem features rectangular segmental precast concrete facing panels and galanized welded wire, grid-type soil reinforcement.
Evaluation Findings for Seismic Energy Products, L.P. Elastomeric Isolation Bearing
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report presents the results of a detailed evaluation for one seismic isolator supplied by Seismic Energy Products, L.P. The evaluation is designed to test the performance of seismic isolators and dampers.
