Effect Of Subgrade Conditions On Pavement Analysis And Performance Prediction: A Study For Idaho Conditions, Md Jibon
Boise State University Theses and Dissertations
The Mechanistic-Empirical (M-E) pavement design approach detailed in the Mechanistic-Empirical Pavement Design Guide (MEPDG), and subsequently implemented through AASHTOWare® Pavement ME Design relies extensively on detailed material properties that ultimately govern the analysis and performance prediction results. For unbound materials like soils and aggregates, Resilient Modulus (MR) is the most critical input parameter affecting layer response under vehicular and environmental loading. Representing a material’s ability to ‘recover’ after loading, resilient modulus is determined in the laboratory through repeated load triaxial testing. Although the original test protocol to measure the resilient modulus value of a soil or aggregate …
Full-Scale Study Of Infrared Thermography For Assessing Surface And Subsurface Defects In Pavements And Other Civil Infrastructure, Aidin J. Golrokh
Full-Scale Study Of Infrared Thermography For Assessing Surface And Subsurface Defects In Pavements And Other Civil Infrastructure, Aidin J. Golrokh
Boise State University Theses and Dissertations
Infrared thermography (IRT) is an effective non-destructive testing method in the field of concrete and asphalt pavements inspection. IRT is used to have an initial evaluation of the surface and near surface of pavements in a very time effective manner compared to other types of nondestructive testing (NDT) methods. Different aspects of IRT and its use to assess surface and subsurface defects in different types of pavements are being studied and evaluated in our research group. The effect of the depth of delamination inside concrete pavement on IRT technique is being studied. It is suggested by our group that there …
Wildfire Smoke: Trends, Challenges, Unknowns, And Human Response, Mariah Dawn Fowler
Wildfire Smoke: Trends, Challenges, Unknowns, And Human Response, Mariah Dawn Fowler
Boise State University Theses and Dissertations
Wildfire smoke is a growing threat to human livelihood in the Western United States. The economic and the health burden of smoke is accelerating in response to a growing fire season and escalating fire activity. This study first evaluates the trends in air quality over Boise, Idaho and the entire Northwest (and Montana) to assess the impacts of wildfire smoke in the region. The Mann-Kendall trend analysis shows that there is a statistically significant trend in the average and maximum air quality index (AQI) during the fire season (July-August-September) in the Boise area. The AQI shows a decreasing trend, although …
A Unified Risk-Based Framework For Assessing Sustainability And Resiliency Of Civil Infrastructure, Thomas Adam Robbins
A Unified Risk-Based Framework For Assessing Sustainability And Resiliency Of Civil Infrastructure, Thomas Adam Robbins
Boise State University Theses and Dissertations
As of February 2019, the National Aeronautics and Space Administration (NASA) has reported since 1880 the average global temperature has increased 1°C, with the warmest year on record being 2016. As the years continue to pass, it is becoming more evident that climate change is occurring, which is known to be a catalyst for climatic weather events. Statistically speaking, these events are more prevalent, and catastrophic exemplified as hurricanes, earthquakes, flooding, and fires. In addition to the increase of potentially catastrophic events, society as a whole has become more conscientious in the use and preservation of natural resources, waste generation, …
