Evaluation Findings For Tekton Inc Steel Rubber Bearings

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report summarizes the results of a detailedØevaluation of steel rubber bearings,Ømanufactured 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 devicesØwere tested for stability, response during earthquake simulations, and fatigue and weathering effects.

Presents the results of a detailed evaluation for one technology out of eleven that were evaluated. The evaluations were designed to test the performance of seismic isolators and dampers produced by several manufacturers.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report describes a program of installation, testing, and evaluation designed to determine the capabilities and limitations of Thermocoax's weigh-in-motion sensor.

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.

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.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report outlines the HITEC Technical Evaluation Plan for large seismic isolator and energy dissipation devices. The plan is designed to characterize the fundamental properties and performance characteritics of a wide range of devices produced by U.S. and overseas manufacturers. It describes a program of full-scale dynamic tests, the results of which should provide guidance to the transportation-engineering community regarding the performance of large seismic devices.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF service center. This report presents the results of a detailed evaluation ofØthe MX 30 pavement marking 30-meter retroreflectometer. The evaluation is designed to test the measurement bias, repeatability, and reproducibility of handheld and mobile retroreflectometers produced by several manufacturers.
