Performance of Mechanically Stabilized Earth Structures When Subjected to Passive Forces
(2019-07-18)
Mechanically stabilized earth structures are increasing in popularity due to their relative ease of construction and favorable performance. Current mechanically stabilized earth designs consider only active pressures ...
A preliminary study on removing vanadium (V) from groundwater using Fe–Mn oxide nanoparticle with different stabilizers
(2018-11-16)
The Vanadium V5+ removal from water body and soil is an important issue for environmental protection and conservation. Nanoparticles as adsorption and the stabilizer against nanoaprticle aggregating have become the key ...
Understanding the evolution of nearshore Deepwater Horizon oil spill residues and characterizing them using GC/MS/MS methods
(2016-01-07)
On April 20, 2010, Deepwater Horizon, a semi-submersible oil rig exploring for oil in the northern Gulf of Mexico (GOM), exploded. The resulting accident released about 4.8 million barrels of oil into the waters of GOM ...
Evaluation of Erosion Control Practices Under Large-Scale Rainfall Simulation Following ASTM D6459 Standard Test Methods
(2020-05-12)
Land development and construction activities remove vegetative cover, exposing bare soil to the erosive forces of rainfall. Stormwater causes dislodgement of soil particles through splash, sheet, and rill erosion, resulting ...
Biopolymers for enhancing the engineering properties of soil
(2020-05-12)
The need for constant construction rapidly expands the built environment which often spreads over areas with unfavorable site conditions. In such events, soil stabilization is an inevitable process. Increasing soil strength ...
Understanding Cyclist Perceptions of Road Adjacent Shared-Use Paths: A Comprehensive Study of Both Stated and Revealed User Preferences
(2020-04-30)
Road adjacent shared-use paths are a valuable transportation facility for rural and suburban communities looking to reap the benefits of increased active transportation. Shared-use paths have the ability to immediately ...
Air-Water Interface Flows in Pipe Emptying
(2020-07-15)
Pipe emptying is an important component of water supply operations. Pipes can be drained as a scheduled operation preceding maintenance, flushed for health reasons or they may empty as a result of an accidental break causing ...
Implementation of Geosynthetic Reinforced Soil- Integrated Bridge System (GRS-IBS) Technology in Alabama
(2020-08-24)
Geosynthetic reinforced soil-integrated bridge systems (GRS-IBS) utilize mechanically stabilized earth (MSE) systems to support single-span bridges. A typical GRS-IBS is made up of three components: the reinforced soil ...
Development of Implementation Guidelines to Assess the Strength of Soil Cement Base in Alabama
(2020-11-16)
Soil cement is a mixture of soil, portland cement, and water that forms a strong, durable, frost-resistant pavement base once compacted and cured. Variation among construction practices and concerns of current quality ...
Reliability of Shear-Critical Reinforced Concrete Members
(2020-05-13)
Recent research on one-way shear strength and strut-and-tie design approach has led to updates in the ACI 318 Building code requirements for structural concrete. The changes in one-way shear design provisions in ACI 318-19 ...
