Leachate Recirculation Modeling Using Vertical Wells In Bioreactor Landfills
(Civil & Environmental Engineering, 2014-09-17)Municipal solid waste (MSW) is made up of household and commercial waste. Total MSW generated in USA in 2009 was 243 million tons and 54.3% of this waste generation was landfilled (EPA, 2009). MSW buried in landfills ... -
LIFE CYCLE ASSESSMENT AND COST-BENEFIT ANALYSIS OF LANDFILL MINING AT THE CITY OF DENTON LANDFILL
(2019-10-23)The concept of landfill mining has evolved the way of transforming the existing landfills from a final waste disposal site to a temporary storage location for the potentially valuable resources. The convergence of the ... -
Local Calibration Of Mechanistic Empirical Pavement Design Guide For North Eastern United States
(Civil & Environmental Engineering, 2011-10-11)The Mechanistic-Empirical Pavement Design Guide (MEPDG) developed under the National Cooperative Highway Research Program (NCHRP) 1-37A project is based on mechanistic-empirical analysis of the pavement structure to predict ... -
Long Term Durability Studies On Chemically Treated Reclaimed Asphalt Pavement (RAP) Materials
(Civil & Environmental Engineering, 2010-03-03)Reclaimed Asphalt Pavement (RAP) is a well known construction material which has been used in Hot Mix Asphalt (HMA) to reduce material costs and stabilizing the pavements for several years. It has been reported that out ... -
Long Term Performance Monitoring of Shallow Slope Stabilization Utilizing Recycled Plastic Pins
(2019-05-14)Shallow slope failures are prevalent within the North Texas region. As highway slopes are underlain with high plastic clayey soils that experience cyclic shrinking and swelling, the soils shear strength generally decreases ... -
