Research Reports Filter by Keyword7 report(s) found with barriers (roads) in the keywords field 1 - 7 of 7 Maintenance costs, while significant throughout the life-cycle of a project, may sometimes not receive full consideration as inputs to design decisions. In Phase I, this project identified research priorities in coordination with the technical advisory committee (TAC) after recommendations were formulated... The objective of this study was to simulate the stress-displacement behavior of a flexible debris-flow mitigation structure with a three-dimensional finite element model (FEM). Flexible, steel ring-net structures are becoming state-of-practice for debris-flow mitigation in mountainous terrain. These... Roadside barriers are the primary structural safety devices on surface roads. They can be made from any material as long as they can absorb the energy involved in an impact scenario. One material that has that potential is Ipe, which is a hardwood material that has relatively high strength compared with... Highway barriers exist in part to protect life and property from excessive danger as part of normal road usage. Typically, these barriers can be characterized as stiff and passive. In this study, we report on the potential use of highly flexible materials that maintain the effective resistance to load... A testing facility for temporary longitudinal barriers was constructed at Colorado State University's Engineering Research Center which allows manufacturer's the opportunity to test their safety barriers prior to full-scale federal testing. This facility enables manufacturers to subject their products... A variety of portable safety and security barriers for directing traffic (public events, sports facilities, etc.), and securing private and public locations against access (court houses, schools, etc.) have been developed. Some higher capacity systems have been developed for use on and around high speed... The goals of this study were to depict the continuing educational needs of Region VIII state transportation departments, to devise alternative methods of educational delivery, and to identify and overcome institutional and technological barriers. Surveys of Wyoming and North Dakota transportation department...
