Research Reports
View AllThis report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. A field load test program was conducted to evaluate three open-deck timber railroad trestle bridges. The bridges included part of a 31-span bridge, a 4-span bridge with skewed interior bents and a 3-span bridge. Plies of the chords of the bridges were evaluated non-destructively for material properties... One potential means for gaining insight into the current state of the elevator industry, and into expectations for future trends, is through a survey. The objective of this study is to profile the transportation and industry characteristics of the elevators located in the Great Plains region of the United... The concept of combining wood and concrete in layered composite bridge deck was investigated. A shear key/anchor detail recently used in Europe to construct floors in office buildings was adapted for this study. This connection detail provides the interlayer shear transfer between the layers. Laboratory... The field of transportation is rapidly becoming a popular career choice for undergraduate engineering students. Many work opportunities are available in the area of transportation including computer software analysis, field testing, and consulting. Unfortunately, these opportunities are not always accessible... Because of the differentiated car program types, it is essential to understand the costs and benefits of each of them. Depending on your situation, a combination of different programs may have the best return for each organization. By providing descriptions of programs, decision makers are able to better... This research examines a range of incident detection technologies to determine a recommended combination of approaches for use in the Utah Department of Transportation (UDOT) Advanced Traffic Management System (ATMS). The technologies that were examined are computer-based Automatic Incident Detection... This report presents results of an investigation into the practice and legal issues of Road Safety Audits and Road Safety Audit Reviews (RSAs and RSARs). These safety analysis approaches focus on identifying safety issues of proposed projects (RSA) and existing roadways (RSAR). In the United States... This report provides a benchmark for elevator managers in assessing performance, and supplies a source for recognizing trends in the characteristics of North Dakota elevators. The objectives of this research were to determine if fly ash has an effect on the field performance of cement-treated bases, determine if cement-treated bases perform similarly to other base types, and develop pavement performance models for interstate and non-interstate roadways in the state of Wyoming. |
