Non-destructive SASW Evaluation Of Controlled Low Strength Material As A Pipeline Bedding Material
(Civil & Environmental Engineering, 2014-09-17)
Evaluation of stiffness properties of subsurface soil layers provides vital insight into the performance of a geotechnical entity. Stiffness properties can be determined by both field and laboratory tests. Owing to their ...
Performance Of Large Diameter Polyvinyl Chloride (PVC) Pipes In Water Applications
(Civil & Environmental Engineering, 2014-03-10)
Polyvinyl chloride (PVC) pipes with diameters greater than 24" make up a small fraction of water utilities. Most of the research done on PVC pipes in water utilities focuses on diameters less than 24". Therefore, this ...
Improving Analysis Of Heavy To Extreme Precipitation Using Conditional Bias-penalized Optimal Estimation
(Civil & Environmental Engineering, 2014-03-10)
Precipitation estimation is a very important topic from the societal perspective as heavy precipitation can cause flooding from which loss of lives and damage to properties can occur. In current practice, a number of spatial ...
The Relation Between Freeway Average Speed And Speed Noise
(Civil & Environmental Engineering, 2014-09-17)
A significant amount of energy could be saved by applying traffic management policies. Many factors affect the fuel consumption rate, and the most important traffic-related ones include variables such as speed, number of ...
Development Of Geopolymer Concrete For Precast Structures
(Civil & Environmental Engineering, 2014-03-12)
This study presents 'geopolymer' as a new binder to replace Portland cement in concrete to make concrete more environmentally friendly and durable. This utilizes industrial by-products like fly ash which is disposed in ...
Evaluating The Performance Of Controlled Low Strength Materials (CLSMs) Prepared Using Sulfate Spiked High Plasticity Clay
(Civil & Environmental Engineering, 2014-03-12)
When large scale civil engineering projects such as Integrated PipeLine (IPL) are to be constructed, several factors play a significant role in the successful completion of the project on time and on budget. With pipeline ...
Performance Comparison Of High Density Polyethylene Pipe
(Civil & Environmental Engineering, 2014-09-17)
The current and forecasted major challenge faced by water utilities is delivering potable water efficiently with minimum loss to end users. Water pipe failure has negative impact not only local communities but also on the ...
Evaluation Of Surface Transportation Funding Alternatives Using Criteria System Established Through A Delphi Survey Of Texas Transportation Experts
(Civil & Environmental Engineering, 2014-03-12)
For more than a decade, transportation officials have been concerned that, at current levels, the fuel tax, the primary funding source of surface transportation in the United States, would not provide enough revenue to ...
Corrosion Potentials Of Lightweight Concrete Wrapped With Fiber Reinforced Polymers (FRP)
(Civil & Environmental Engineering, 2014-03-12)
The purpose of this research was to investigate the effects of Fiber Reinforced Polymer wraps on corrosion protection of lightweight concrete. Many studies have been undertaken for normal density concrete, but there are ...
Finite Element Modeling Of Prestressed Girder Strengthening Using Fiber Reinforced Polymer And Codal Comparison
(Civil & Environmental Engineering, 2014-03-12)
Fiber Reinforced Polymer (FRP) composite materials provide effective and potentially economic solution for rehabilitating and upgrading the existing reinforced and precast concrete bridge structures that have suffered ...
