Filter by Keyword135 report(s) found with roads in the keywords field Untreated native soil with high swell potential has been identified by the Colorado Department of Transportation as one of the major contributing factors in the development of premature longitudinal cracking and other pavement distresses in Colorado (Ardani et al. 2003). Unique regional factors such... An integrated mobile testing study that utilized a large truck equipped with various testing equipment was conducted on Interstate I-70 in Colorado. The field study integrated wind measurement, vehicle dynamic monitoring and geospatial multimedia technology on a real-time and synchronized basis. Essential... 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... This report details the results of a project aimed at determining how to legally establish a county road in Wyoming. This report covers the laws on this issue from territory days until the present. It consists of a survey, case law, statutory law, federal law, direction and a final desk reference. The... Animal-vehicle crashes are a concern for many areas of the country but are a particular concern for rural areas such as Wyoming. While there is considerable literature available on the effectiveness of various animal-vehicle countermeasures, such as fencing and signing, there is currently little quantifiable... A county road planning process was developed that would facilitate the best use of scarce resources and that could be easily adapted to a county's unique situation. The planning process was used to create a county road plan for Cass County, North Dakota, and the process was modified during the project... 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... The movement of freight within the state of Wyoming is very critical to Wyoming's economy as well as the national economy. Wyoming's transportation system provides a vital link for the movement of commodities across the United States, in addition to providing access to the mineral, industrial, and agricultural... The study focuses on ascertaining information on user willingness-to-pay and their perceptions of funding for improving gravel roads which support freight transportation service in rural areas. The research considers safety, road type, and maintenance valuation for both gravel and paved road surfaces.... This report describes a research project conducted at Colorado State University to evaluate the effect of road dust suppression on unpaved road maintenance schemes. A field-based method was used to measure the effect of road soil physical characteristics on the effectiveness of some of the commonly... |
