Book Description
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report summarizes the results of a detailedØevaluation of base isolation elastomeric bearings,Ømanufactured by Skellerup. 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.

Book Description
Prepared by CEITEC, a CERF innovation center serving the engineering and construction industries. This report describes an evaluation of Sewer Scanner and Evaluation Technology (SSET) designed to determine the basic capabilities and limitations of SSET for use as a technicallly viable technology for inspecting sewer pipes. The evaluation focused on the performance and in-service demonstration of SSET. The technology involves digital scanning to obtain a flat, "unfolded" image of the pipeline's interior. This evaluation includes field demonstrations performed at 13 municipal public works agencies throughout North America. Subsequent to this evaluation, SSET was modified to include a fisheye lens camera and fiber optic gyroscope, which replaced the rotating mechanical scanner and mechanical gyroscope. The evaluation confirmed the operability of SSET and its viability in data presentation. A degree of enhancement was recognized with additional features, most notably the ability to produce a digital report of the sewer pipe, to identify vertical deflection in pipes, and to deliver easily comprehensible and manageable results. The evaluation also revealed that SSET cannot reproduce all the features typically available from closed-circuit television (CCTV) inspection. Such features include the ability to clearly see corrosion, infiltration rates, and ovality. The limitations in applicability were determined and an economic comparison of SSET and CCTV is provided.

Book Description
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.

Book Description
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.
