Cover of Summary of Evaluation Findings for the Testing of ICE BAN
This report describes a laboratory and field evaluation to determine the effectiveness of Ice Ban anit-icing/deicing products in snow removal and ice control operation on roads. Field demonstrations conducted by eight state transportation agencies are summarized, and the effects of the ice control agent on highway structures and vehicles are assessed.

Cover of 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.

This 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.

Cover of Evaluation of the Isogrid Retaining Wall System

Prepared by the Highway Innovative Technology Evaluation Center, a CERF service center.

This report presents the results of a HITEC evaluation of the Isogrid Retaining Wall System, designed and developed by the Neel Company. The report describes the basic capabilities and limitations of the Isogrid System for use as a technically viable precast, mechanically stabilized earth retaining wall system. The evaluation was conducted based on material, design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The Isogrid System features a diamond-shaped, segmental precast concrete facing panel with weep holes where four panels intersect and welded wire, grid-type soil reinforcement attached to the center of each facing panel.

Cover of Evaluation Findings for Tekto, Inc. Steel Rubber Bearings

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center.

This report summarizes the results of a detailed evaluation of steel rubber bearings, manufactured by Tekton, Inc. The report is part of a program to test the performance of 11 seismic isolators and dampers produced by several manufacturers. The devices were tested for stability, response during earthquake simulations, and fatigue and weathering effects.
