The Development of Initial Asphalt Mixture Acceptance Criteria Using the SCB test and the I-FIT Test
… Arkansas. The Illinois Flexibility Index Test (I-FIT) was the test chosen to analyze for this research. Two aging methods were tested, a short term oven aging (AASHTO R30 ST) and a long term oven aging (NCAT) method. Six asphalt mixtures were selected to be tested. The mixtures testes were …

An analysis of impact factors on the Illinois flexibility index test
… may negate any environmental or economic benefit initially obtained from the use of recycled materials. The typical modes of failure for asphalt pavements with high recycled content are thermal cracking or early fatigue cracking. While RAP and RAS contribute a significant amount of recycled …

Effect of specimen geometry and test configuration on the fracture process zone for asphalt materials
… to provide environmental and economic benefits by decreasing the use of virgin materials, such as natural or quarried aggregates and asphalt binder, in newly designed asphalt mixtures. However, recycled materials such as reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) …

Impact of laboratory simulated aging on asphalt concrete flexibility
… using the Illinois Flexibility Index Test (I-FIT) after the specimens were subjected to various lab-simulated long-term aging conditions. The flexibility index (FI), an outcome of the I-FIT and a measure of the AC flexibility. decreases consistently after long-term aging. This effect is …

Development of a performance-based test method for quantification of cracking potential in asphalt pavement materials
… method, the Illinois Flexibility Index Test (I-FIT), was developed, and found to appropriately distinguish between variations in mix design and characteristics. The I-FIT method is a modification of the semicircle bending beam (SCB) test; the modification includes the testing temperature, the …

Determinations of the radii, redshifts, and atmospheric compositions of neutron stars from modeling their Chandra X-ray spectra
Fitting the X-ray spectra of thermal radiation from neutron stars with realistic atmosphere models provides a way to place constraints on their radii, surface gravities and compositions, and to test general relativity in the strong field limit. Such determinations allow us to constrain the the …

Balancing asphalt mixes containing recycled materials for optimum field performance
… test, and the Illinois flexibility index test (I-FIT) was conducted to evaluate thermal cracking susceptibility, rutting, and cracking resistance, on plant-mixed lab-compacted (PMLC) mixes and three sets of field cores. The extensive exploratory data analysis on creep compliance showed that softer …

Laboratory assessment of asphalt concrete durability utilizing balance mix design
… using the Illinois Flexibility Index Test (I-FIT) and the Hamburg Wheel Track Test (HWTT). Additionally, mix stiffness and moisture damage susceptibility were evaluated using the output data from I-FIT and HWTT, respectively. The tests results were analyzed using the Illinois Balance Mix …

Wolf Selection of Human-Modified Linear Features and Cover Types When Hunting and Killing White-Tailed Deer Fawns
… wolves hunt and kill fawns. During 2016–2019, I fit wolves with 20-min-fix-interval Global Positioning System (GPS) collars and searched clusters of GPS-locations to identify where wolves killed fawns. I identified 217 wolf-killed fawns from 12 wolves. I then created 4 models to predict where …

When the Map Fails the Territory: Hidden State Models, Complex Traits and the Evolution of Bird Migration
… American birds (Chapter ref{ch:2}). Next, I fit SHMMs informed by this structure to global and North American bird phylogenies, testing hypotheses about how migration may have evolved, while accounting for classification ambiguity (Chapter ref{ch:3}). I show that models incorporating hidden …

Non-Linear Density Dependence in a Stochastic Wild Turkey Harvest Model
… between population growth and density, I fit the theta-Ricker model to harvest index time-series from 11 state wildlife agencies. To model density-independent effects on population growth, I explored the ability of rainfall, temperature, and mast during the nesting and brooding season to …
