Effect of Impurities in Plastic Waste on the Performance of Plastic road
(2023-08-17)**Please note that the full text is embargoed until 08/01/2025** Plastic waste generation has become a global concern, with a large portion of plastics ending up in landfills. China's recent decision to stop importing waste ... -
Effect of Mixing on Monochloramine Formation through In-line Injection of Chemicals in Water Disinfection Process
(2019-08-01)Addition of chlorine and ammonia to water for monochloramine formation in the secondary disinfection process in treatment plants has some challenges. Monochloramine formation as the only desirable product of the chloramination ... -
EFFECT OF MODIFIED MOISTURE BARRIER IN MITIGATING PAVEMENT DISTRESSES DUE TO EXPANSIVE SUBGRADE
(2021-05-07)Surficial distresses in roadways of Texas are very common due to presence of high plastic clayey soil in the subgrade. Increased sensitivity of high plastic clay towards seasonal moisture change results in repeated swelling ... -
Effect of Modified Moisture Barriers on Slopes Stabilized with Recycled Plastic Pins
(2019-08-09)High plasticity expansive clayey soils are prone to repeated swelling and shrinkage due to cyclic climatic variations. These variations lead to desiccation cracks that act as pathways for rainfall intrusion into the slope, ... -
Effect Of Pavement Type On Fuel Consumption In City Driving
(Civil & Environmental Engineering, 2012-04-11)Vehicular fuel consumption and emissions are two increasingly important measures of effectiveness of sustainable transportation systems, particularly considering that mobile sources in the U.S. account for the largest ... -
EFFECT OF TERMITE GUT MICROORGANISM TAV5 RATIOS ON LIGNIN DEGRADATION AND METHANE GENERATION FROM PAPER, YARD, AND WOOD WASTE
(2019-05-08)Methane from anaerobic processes is being increasingly utilized as an alternative energy source in developed countries, via large projects that extract methane from landfills or wastewater treatment plants. Anaerobic ... -
EFFECTIVENESS OF RECYCLED PLASTIC PIN FOR IMPROVING BEARING CAPACITY OF EMBANKMENT OVER SOFT SOIL
(2021-08-16)Construction of embankment over soft foundation soils is incredibly a challenging task due to the risk of bearing failure and excessive settlement of foundation soil. Most of the available conventional methods for addressing ... -
EFFECTS OF CLIMATIC LOADING IN FLEXIBLE PAVEMENT SUBGRADES IN TEXAS
(2017-12-07)Expansive soils, which have been reported as a worldwide problem, cover 25% of the United States. Due to the swelling and shrinkage behavior induced by moisture variations, expansive soil contributes to volumetric deformation, ... -
Enhanced Seismic Performance of Special Truss Moment Frames and Staggered Truss Framing System for Seismically Active Areas
(2016-05-10)Due to their ability to achieve large column-free floor spaces, special truss moment frames (STMFs) and staggered truss frames (STFs) are unique valuable options for structural engineers. However, although STMFs and STFs ... -
Enhanced Shrinkage Characterization of Clayey Soils
(2015-11-30)Surficial slope failure is a common problem experienced by most of the compacted earth dams in Texas and several other southern states in USA as a result of desiccation or shrinkage induced cracking of the surficial soils. ... -
Enhanced Viscoelastic Modeling Of Hot Mix Asphalt
The primary objective of this research is to investigate the relationships between Compressive (CDM) and Tensile Dynamic Moduli (TDM) of Hot Mix Asphalt (HMA) and develop a material model that predicts tensile dynamic ... -
ENHANCEMENTS OF SHEAR TESTS FOR ASPHALT CONCRETE
(2019-12-04)The measurement of the fundamental shear properties of asphalt mixes is imperative to the improvement of modelling of rutting development in asphalt concrete. The Duplicate Shear Tester (DST) is a recent device developed ... -
ENHANCING ANAEROBIC OXIDATION OF METHANE IN LANDFILL COVER SOIL
(2019-05-13)Methane (CH4) is one of the major greenhouse gases (GHG) generated in landfills and has a global warming effect 28 times more than carbon dioxide (CO2). Therefore, decreasing methane emissions into the atmosphere from ... -
