Use of Dynamaic Cone Penetrometer versus other Field and Lab tests for Subsurfase Characterization
The purpose of this research was to correlate the results of the Dynamic Cone Penetrometer (DCP) used in surface characterization with presently trusted methods of testing such as the Nuclear Density Gauge (NDG), sand cone, ...
Submerged-Membrane Bioreactor for the Treatment of NASA Wastewater
Potable water represents a key component of life support for extended-duration space missions and the continued operation of the International Space Station. Treatment systems for the recycling of wastewater collected from ...
Impact of Anti-Strip Additives on Performance of Asphalt Pavements
Typically, lime and liquid are used as additives to combat moisture damage, and therefore, their impact is only evaluated with respect to their influence on the moisture sensitivity of the HMA mixture. This study extended ...
Occurrence, Fate and Transport of the Primary Metabolites of Trenbolone Acetate in CAFO Soils and Surface Water Runoff
Metabolites of synthetic growth promoters used in industrial cattle production pose a demonstrated ecological risk to waterways adjacent to beef feedlot operations. For example, numerous studies have linked reproductive ...
Impact of Contact Stress Distribution and Pattern on Asphalt Pavement Performance using 3D-Move Analysis Software
This research evaluated the impact of the contact stress distribution and pattern on asphalt pavement responses and pavement performance. The impact on pavement performance was evaluated using mixtures' specific fatigue ...
Properties of Warm Mix Asphalt from Two Field Projects: Reno, Nevada and Manitoba, Canada.
This study was geared towards evaluating the properties of warm mix asphalt (WMA) mixes that were obtained from two field projects; Reno, NV and Manitoba, Canada, in the laboratory, relative to conventional hot mix asphalt ...
The Role of Biodegradable Dissolved Organic Carbon On the Degradation of Pharmaceuticals and Personal Care Products During Soil Aquifer Treatment
As human populations continue to grow and global climate changes occur, the water required to sustain arid regions is becoming scarce. One option to increase future water supplies in arid regions is to store water in ...
Sediment Transport Analyses and Development of a Hydraulic Computer Model for Desiging a Stable Vegetated Channel at Lost Lake
The erosion and transport of mine tailings containing arsenic is occurring at several locations within the Lost Lake watershed in the vicinity of Nevada City, California. The source of the tailings is the abandoned Lava ...
Stability of Bridge Column Rebar Cages during Construction
The lateral behavior and stability of bridge column rebar cages were investigated to reduce the potential of failure and collapse during construction. Rebar cages are temporary structures made of longitudinal and transverse ...
