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...

 

To improve the pavement design and construction in Wyoming, the Wyoming Department of Transportation (WYDOT) is adopting the Mechanistic-Empirical Pavement Design Guide (MEPDG). A full implementation of MEPDG requires the characterization of local crushed base materials. In this research, laboratory...

 

To facilitate the implementation of Mechanistic-Empirical Pavement Design Guide in Wyoming, this research investigated the relationships between subgrade resilient modulus (Mr) and the dynamic cone penetration and the standard penetration test results, selected three best subgrade Mr predictive models...

 

Scour of spill-through abutments occurs due to the combined influence of geotechnical and hydraulic processes. The present study is among the first to address the geotechnical process associated with the failure of the compacted earth, spill-through abutments, and the effects of the geotechnical strength...

 

Conventional test methods for roadway compaction cover less than 1% of roadway; whereas, intelligent compaction (IC) offers a method to measure 100% of a roadway. IC offers the ability to increase compaction uniformity of soils and asphalt pavements, which leads to decreased maintenance costs and an...
