Comparison Of Dust Generation From Open Cut And Trenchless Technology Methods For Utility Construction
(Civil & Environmental Engineering, 2011-07-14)
Construction industry has changed many aspects of human life and is still evolving at a rapid pace. New and better technologies which are environmentally friendly and safe are being introduced in this industry. But with ...
Development Of A Model Of Productivity For Horizontal Directional Drilling (HDD)
(Civil & Environmental Engineering, 2011-10-11)
Horizontal Directional Drilling (HDD) is a growing method for installation of pipes in urban areas and where ever trenching is impossible or undesirable; such as in crossing rivers, lakes, and railways, and special areas ...
A Non-invasive Assessment Of Moisture Content Of Municipal Solid Waste In A Landfill Using Resistivity Imaging
(Civil & Environmental Engineering, 2011-10-11)
A bioreactor landfill is operated to enhance waste decomposition, gas production, and refuse stabilization. The fundamental aspect in the operation of a bioreactor landfill is the controlled addition of water and/or the ...
Carbon Footprint Analysis Of A Large Diameter Water Transmission Pipeline Installation
(Civil & Environmental Engineering, 2011-07-14)
The term pipeline refers to a long line of connected segments of pipe, with pumps, valves, control devices, and other equipment or facilities needed for operating the system. Water transmission pipelines are generally large ...
The Effects Of A Variable Modulus Of Elasticity On Prestress Losses In Bridge Girders
(Civil & Environmental Engineering, 2011-10-11)
The purpose of this research is to evaluate a method proposed by Franz Dischinger (Dischinger, 1939) to consider the effects of a variable modulus of elasticity (MOE) of concrete over a period of time. Current guidelines ...
Unsaturated Soil Behavior Under Large Deformations Using A Fully Servo/suction-controlled Ring Shear Apparatus
(Civil & Environmental Engineering, 2011-07-14)
In recent years, the key hypotheses of most elasto-plastic constitutive frameworks postulated for unsaturated soils have been validated via suction-controlled oedometer, triaxial, and direct shear testing. These techniques, ...
An Investigation Of Productivity Loss Due To Outdoor Noise Conditions
(Civil & Environmental Engineering, 2011-07-14)
Most people in day to day life at one time or other get irritated or distracted by surrounding noises. The irritation might have resulted in minor aggravation or may have been dramatic enough to hinder their work. This ...
Evaluation Of Trenchless Renewal Methods For Potable Water Distribution Pipes
(Civil & Environmental Engineering, 2011-03-03)
Undoubtedly, potable water pipes, as part of an underground infrastructure system, play a key role in maintaining quality of life, health and well being of human kind. As these potable water pipes reach the end of their ...
Characterization And Evaluation Of Gas Generation Potential Of Municipal Solid Waste From A Closed Section Of A Landfill
(Civil & Environmental Engineering, 2011-10-11)
At present, there are more than 40 closed municipal solid waste (MSW) landfills around DFW and North Texas. A closed landfill might have potential benefits for gas recovery and utilization due to the presence of organic ...
Nano-modified Cement Composites And Its Applicability As Concrete Repair Material
(Civil & Environmental Engineering, 2011-10-11)
Nanotechnology or Nano-science, considered the forth industrial revolution, has received considerable attention in the past decade. The physical properties of a nano-scaled material are entirely different than that of bulk ...
