Prediction of in-situ asphalt mixture density using ground penetrating radar: theoretical development and field verification
… density measurement: laboratory testing on field-extracted cores, and in-situ nuclear gauge testing. However, both these methods have limitations. The coring method damages pavement, causes traffic interruption, and only provides limited data at discrete locations. The nuclear gauge method …

Development of a pile condition index and a road map for the development of a structural section rating
… engineers. Results obtained through limited field verification indicate good correlation between computed Pile CI ratings and average expert panel field ratings. The Delphi method was successfully employed as a novel approach to further validate the weighted deduct-density model. Results from …

Hydraulic Characterization of Interlocking Concrete Permeable Pavement
… infiltration rate which is currently used in field verification. The results also showed that the infiltration rates are inversely related to the cross slope of the pavement. Additional research included permeable concrete pavement as an alternative sub-base and clogging tests which included …

Detection of Hydrogen in a Two-Phase Cryogen Flow Stream with Thermal Protection Design Configurations
… safety of the personnel. Initial calibration and field verification on the hydrogen sensor were performed to ensure proper operation in an ideal environment and to prepare the sensor for testing outside the manufacturer-specified limits. Several configurations were implemented to optimally balance …

Identifying Locations Of Highly Eroded Agricultural Land In The Devils Lake Basin, ND Using GIS Terrain Analysis Modeling
… (79%) of the 116 survey points established for field verification. Finally, the findings support that the use of terrain analysis for erosion modeling in the Devils Lake basin is highly accurate, and can be a useful tool in locating and implementing best management practices (BMPs) to aid in the …

Effects of Road Characteristics, Land Cover, and Topography on Roadkill Patterns Across a Rural-Urban Gradient in Southwest Virginia
… data sets, satellite imagery, and field verification to characterize our study routes. I recorded 294 carcasses and identified 221, of which 84% were small or meso-mammals, including 11 taxa. The most frequent roadkill taxa were tree squirrels (Sciurus sp.), opossums (Didelphis …

Delineation of Karst Potential Using LiDAR and GIS Analyses, Fort Hood Military Installation, Texas
… karst surveys require extensive field investigations to completely characterize large areas. They are often time-consuming, requiring up to several years to collect and categorize data. Bias is given to areas that are most easily accessible and false negatives are common. The …
