This report discusses the benefits of full-scale pavement testing and the use of accelerated pavement testing (APT) to collect pavement performance data under actual experimental conditions. The report highlights the development and operation of road test tracks, such as the Minnesota Road Research Project...
Two-lane highways comprise a considerable percentage of the nation's roads. A critical component required in the design of two-lane highways is the passing sight distance (PSD). In cases where it is inadequate, no-passing zones are established. There are multiple techniques employed for measuring the...
This research explores the influence of thermo-mechanical beneficiation methods on the physicochemical characteristics and reactivity of fly ashes disposed of in landfills (LFAs) obtained from power plants in Wyoming and Colorado, USA. An in-depth assessment was conducted on the mechanical and performance...
The condition of concrete on bridge decks is one of the most costly parts of Wyoming Department of Transportation's budget and the cost of maintenance can result in inadequate roads or costly premature repairs. This proposal evaluates critical factors relating to early age shrinkage and proposes combining...
Truck crashes on steep downgrades caused by excessive brake heating is an ongoing concern for the Wyoming Department of Transportation (WYDOT). Crashes resulting from brake failure on downgrades cause a devastating toll on lives and property. To counter such crashes, WYDOT initiated a research project...
Considering traffic safety concerns and challenging driving conditions on Interstate 80 in Wyoming, the United States Department of Transportation (USDOT) and Federal Highway Administration (FHWA) selected an I-80 400-mile freeway corridor as one of the three sites in the United States to develop, test...
Road safety is a crucial topic of transportation engineering. The Wyoming Department of Transportation (WYDOT) collects such data from police crash reports and roadway inventories. WYDOT also provides those data to its partner groups in the form of data records or summary statistics documented in periodical...
This study evaluates a comprehensive experimental investigation to better understand the mechanical and deformation behavior of Wyoming bedrocks and therefore to improve the design and construction of transportation infrastructure. Fifty-six rock samples were collected from different locations around...
This study aims to improve the efficiency of driven piles in intermediate geomaterials (IGMs) to increase the reliability of pile foundations for bridge structures. Test pile data collected from the seven state DOTs and total 223 pile load test data are evaluated to provide recommendations for driven...
Adverse weather has long been recognized as one of the major causes of motor vehicle crashes due to its negative impact on visibility and road surface. Providing drivers with real-time weather information is therefore extremely important to ensure safe driving in adverse weather. However, identification...
