LABORATORY STUDY OF HYDRODYNAMICS OF SUBMERGED BRIDGES
(2020-12-08)Bridges are designed to withstand flood and debris loads; however, it is reported that 53% of bridge failures in the U.S. are caused by hydraulic events, including floods, scour, debris, and drifts. A series of scale flume ... -
LABORATORY TESTING AND FINITE ELEMENT MODELING OF INVERT REMOVED CORRUGATED METAL CULVERT BURIED UNDER SHALLOW COVER
(2019-08-28)Ever since their advent in the 1800s, corrugated metal pipes (CMPs) have played a vital role in this nation’s infrastructure. The wide range of options on diameter and span have made these culverts more preferable over ... -
Laboratory tests and numerical model of geothermally heated bridge deck with attached hydronic loop
(2020-12-17)An accumulation of ice and snow on pavement slabs and bridge decks always adversely impacts driving conditions and results in motorist accidents. The use of the more popular deicing methods, including plowing, salting, and ... -
LANDFILL VOLUME GAIN FROM THE DIVERSION OF CONSTRUCTION AND DEMOLITION WASTE
(2015-12-09)Construction and Demolition (C&D) waste is one of the major components of the solid waste and is defined as a waste stream resulting from the construction, renovation and demolition of structures such as buildings, roads, ... -
Large Diameter Steel Pipe Field Test Using Controlled Low Strength Material And Staged Construction Modeling Using 3-D Nonlinear Finite Element Analysis
(Civil & Environmental Engineering, 2014-03-12)Using finite element methods and field tests, an extensive study on selected steel pipes is devised for the Integrated Pipeline Project in Dallas-Fort Worth, Texas. The project integrates Tarrant Regional Water District ... -
The Last Planner System For Realiable Project Delivery
(Civil & Environmental Engineering, 2012-04-11)The Last Planner System is a production planning system designed to produce predictable work flow and rapid learning in programming, design, construction and commissioning of projects. The Last Planner System (LPS) is ... -
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 ... -
Life Cycle Assessment Of Bio-material Stabilized Expansive Soils
(Civil & Environmental Engineering, 2008-09-17)Pavement cracking is one of the major maintenance works that requires millions of dollars in repair costs annually. Pavement cracks are formed due to moisture and temperature fluctuations in the soil. Stabilization of ... -
