This webinar will present the research findings of the Mountain-Plains Consortium Research Project 480. This research was based on innovative geometric designs as a solution to the challenge of increased traffic volume with limited resources. This particular study focused on diverging diamond interchanges. The...
Accelerated Bridge Construction (ABC) has been implemented in bridge construction because it provides advantages for commuters in urban areas. Prefabrication of bridge structural components is a highly effective method and is one of the ABC methods of Prefabricated Bridge Elements and Systems (PBES)...
Automated Image-Based Aircraft Tracking and Record-Keeping for Utah Airports considers that over 97% of the United States airports are not equipped with control towers. As a result, these airports need an alternative solution to monitor their airport-level aircraft operations, including departures, arrivals...
This webinar will present the research findings on the Mountain-Plains Consortium Research Project MPC-407 on drivers and cell phone usage. Two research reports were created during this project: Why Drivers Use Cell Phones and Support Legislation to Restrict This Practice, Report MPC-17-323 Cell...
Asphalt binder used for pavement construction is obtained mainly by the distillation of crude oil in refineries. The scarcity of natural resources, environmental concerns, and emerging needs for sustainable materials have spurred the development and use of materials and processes that are renewable and...
Fiber reinforced concrete has been used in bonded resurfacing overlays and assumed to have improved performance, as well as cost-effective. The benefit of improved toughness by incorporating fibers has proven to reduce cracking, yet other deformation characteristics and the bond interaction to the underlying...
A mechanical bar splice, also known as bar coupler, is an alternative to the traditional lap splicing to connect bars in reinforced concrete (RC) structures. Even though mechanical bar splices can be used as new precast column connections to accelerate bridge construction (ABC), the use of bar couplers...
This presentation will cover research conducted by South Dakota State University under the Mountain-Plains Consortium Project 437 and with additional funding from SDDOT. There is little guidance for SDDOT pertaining to the use and testing of FRC. There is also lack of information about new fiber products...
Seismic resilience of bridges improves safety and livability of communities. Successful completion of the project will ensure that the proposed method of constructing bridges will improve seismic resilience of bridges for strong earthquakes thus preserving the existing transportation system. The project...
This presentation is based upon Mountain Plains Consortium Research Project 18-367 – Identification of Fatigue Countermeasures for the Short Line Railroad Industry. However, the results of this research are applicable to all transportation sectors in that fatigue applies to human operators in all modes...
