Analysis of the Effects of Global Changes upon US Air Quality and North American Background Ozone
This dissertation develops an analysis of changes in United States air quality in response to changes in climate and in global and local biogenic and anthropogenic emissions. Results from a global climate model driven with ...
Characterization and Modeling of Shrinkage Cracking of Cementitiously Stabilized Layers in Pavement
This research identifies the properties of cementitiously stabilized materials that significantly affect shrinkage cracking in pavements with cementitiously stabilized layers. Methods for measuring these properties are ...
INVESTIGATION OF THE FRACTURE HEALING AND MECHANISM OF ASPHALT BINDERS
The self-healing properties of viscoelastic asphalt materials have been widely recognized among pavement researchers which can result in extended service life of asphalt pavements. The study of asphalt healing has mainly ...
MICROSTRUCTURAL ANALYSIS OF UNSATURATED GRANULAR SOILS USING X-RAY COMPUTED TOMOGRAPHY
This study presents microstructural characterization of partially saturated granular soils using X-ray computed tomography (CT). In the funicular and pendular saturation regimes of unsaturated soils, pore-water assumes a ...
Modeling the deformation of unsaturated granular pavement subgrade materials
This dissertation presents the development and implementation of a constitutive model to predict the behavior of unsaturated sands. The model is based on critical state and bounding surface concepts and incorporates ...
