Asphalt mixtures were collected from seven field projects and distributed to different laboratories to determine their potential for cracking. Samples were prepared in the lab for testing at two conditions: low, in-service temperatures using the bending beam rheometer device based on AASHTO TP-125 and...

 

Speed limits play a pivotal role in traffic safety on mountainous roadways. Due to Wyoming's unique conditions, designing mountainous roadways with appropriate design speeds is challenging. These roadways are characterized by adverse weather conditions and tight horizontal curves with steep downgrades...

 

Several approaches are presented that allow for a direct path of image-to-analysis for the mechanics of structures using a combination of structure-from-motion (SFM) and the finite element method. Through these methods, conventional computational methods can be applied to models created from digital...

 

Stormwater runoff generated in urban areas can increase the risks of flooding and contaminate surface waters. Various contaminants carried by stormwater runoff can negatively affect the water quality of receiving water bodies. Many of the conventional stormwater best management practices are designed...

 

North Dakota's current driving under suspension (DUS) law, enforcement, and effects are explored from the perspective of the state's municipal and district court judges (including judicial referees/magistrates). Overall weighted results are presented in addition to between-group distinctions. These insights...

The objective of this study was to determine the effectiveness of commercially available polymer soil stabilizers in expansive soil swell reduction relative to quicklime and Class C fly ash. A survey of state departments of transportation within the Mountain-Plains region of the United States (Colorado...

 

This study evaluates two versions of the new super diverging diamond interchange (Super DDI) design as a possible alternative to improve the performance of failing service interchanges in the Denver, Colorado, metro. Three interchanges, Interstate 225 and Mississippi Ave, Interstate 25 and 120th Ave...

 

Urban traffic networks consisting of partially blocked roads often need to remain open to traffic before, during, and after disasters because of their vital roles to hazard preparation, emergency response, and recovery of urban communities. Conducting effective traffic planning of disrupted transportation...

 

An efficient and timely rescue of injured people by emergency medical services (EMS) is essential to saving as many lives as possible following disasters. Disrupted traffic networks due to the failures of transportation infrastructure (e.g., bridges) following major disasters like earthquakes affect...
