Laboratory Investigation Of Type I And Type Ii Hardened Cement Emulsified Asphalt Mortar, Tyler E. Rutherford
Laboratory Investigation Of Type I And Type Ii Hardened Cement Emulsified Asphalt Mortar, Tyler E. Rutherford
Masters Theses
The research presented in this thesis investigated the mechanical and viscoelastic properties of a relatively new construction building material that has been given a lot of attention in the past decade. Cement emulsified asphalt mortar (CEAM) has unique properties that differ from concrete and asphalt binder alone as this hybrid material combines the high strength of portland cement composites and the flexibility of asphalt materials. Functioning as a damping material for ballastless high-speed rail track bed, CEAM has the potential to be utilized in other areas of construction.
The work presented in this thesis is broken down into two studies, …
Long-Term Evaluation Of Norris Reservoir Operation Under Climate Change, Joseph Patton Rungee Ii
Long-Term Evaluation Of Norris Reservoir Operation Under Climate Change, Joseph Patton Rungee Ii
Masters Theses
This study aimed to address the potential long-term effects of future climate change on the Tennessee Valley Authority’s (TVA’s) operation policy for Norris Reservoir. The Community Earth System Model 1.0 (CESM1.0), a general circulation model (GCM) accessible through the Intergovernmental Panel on Climate Change’s (IPCC’s) Coupled Model Intercomparison Project Phase 5 (CMIP5), with the Representative Concentration Pathway 4.5 (RCP4.5) was used to obtain projected precipitation and temperature data for three future climate scenarios, 2030’s, 2050’s, and 2070’s. Three hydrologic models were individually calibrated on 30 years of observed runoff data and combined utilizing linear programming to consider the strengths of …
A Spatial Analysis Of Streambank Heterogeneity And Its Contribution To Bank Stability, Paul Vanterpool Simmons
A Spatial Analysis Of Streambank Heterogeneity And Its Contribution To Bank Stability, Paul Vanterpool Simmons
Masters Theses
Streambank erosion is a function of fluvial detachment and geotechnical failure mechanisms working in combination to cause bank retreat. It is generally agreed that bank stability is dependent on both types of erosion; however, few studies have attempted to correlate the driving and resisting forces between the two. It has been proposed that: (1) streambanks possess a spatial structure and dependence of non-erodible resistant structures such as root masses and rocks; (2) streambanks naturally “armor” themselves from fluvial erosion with a combination of hard points and resistive soil; and (3) the stability of the streambank can be predicted by the …
