Since release of the MEPDG in 2004, many national and state agencies have been working toward implementation of the new pavement design guide through calibration and validation. In order to aide Wyoming's Department of Transportation in its push toward total implementation, this study developed a set...

 

Motorists and wildlife are at risk when wild animals enter highways at access roads that bisect wildlife exclusion fencing. Cattle guards are common at access roads, but are ineffective wildlife barriers. Electrified pavement is an emerging technology previously untested as an ungulate deterrent. Our...

 

North Dakota currently designs roads based on the AASHTO Design Guide procedure, which is based on the empirical findings of the AASHTO Road Test of the late 1950s. However, limitations of the current empirical approach have prompted AASHTO to move toward the new mechanistically based pavement design...

 

To date, BIM (Building Information Modeling) is not widely utilized in infrastructure asset management. Benefits achieved through implementation in vertical construction, however, suggest that BIM represents significant opportunity for gains in process, material, and economic efficiency throughout infrastructure...

 

Street networks designed to support Transit Oriented Development (TOD) increase accessibility for non-motorized traffic. However, the implications of TOD supportive networks for still dominant vehicular traffic are rarely addressed. Due to this lack of research, decision making in favor of TOD supportive...

 

This report presents a two-part research program examining the performance of constructed bridges in a cold region, represented by those in the State of North Dakota, and the behavior of concrete members strengthened with carbon fiber reinforced polymer (CFRP) composite sheets in such a service condition....

 

Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also...

 

This report describes research performed in coordination with work at the University of Stuttgart, attempting to establish the S-N curve for fatigue loading of notched wood-concrete connections based on low/high-cycle, repeated loading tests. Experimental results are obtained on fourteen 1524 mm span...

 

This research compares safety, measured by expected crash frequency and severity, on road segments where design exceptions were approved and constructed to similar road segments where no design exceptions were approved or constructed. Data were collected for design exceptions in Utah in the years 2001...

 

This research focuses on finding a method for creating cost effective and innovative steel bridges in Colorado. The design method that was discovered to create this cost efficiency was designing the beams as simply supported for non-composite dead loads, beam weight and wet concrete, and then making...
