Bridge Pile Bent P-Delta Curves in Transverse Direction Using FB-Pier and GTSTRUDL Pushover Analysis Procedures
(2008-09-09)
Extreme flood events may create large transverse water loads that cause piles of a bent to bend about their weak axes in addition to causing scour. A comparison of the nonlinear pushover analysis procedures and resulting ...
Evaluation of Self-Consolidating Concrete for Use in Prestressed Girder Applications
(2008-09-09)
Self-consolidating concrete (SCC) is a highly flowable, yet cohesive, concrete that is able to fill formwork and completely encapsulate any reinforcement without the need for external vibration. The use of SCC may help ...
A Statistical Analysis of Georgia's HMA Quality Assurance Proccess
(2008-09-09)
In the recent years, there has been a push towards allowing contractors to use their own test results in the quality assurance process of Departments of Transportation (DOTs). While this movement saves the states money ...
Evaluation of the Maturity Method to Estimate Concrete Strength
(2008-09-09)
The strength of a newly constructed concrete structure or roadway is critically important to contractors and engineers who must decide when to safely allow construction loads, prestressing operations, or opening to traffic ...
Transfer Length in Prestessed Self-Consolidating Concrete
(2008-09-09)
Over the years much research into the transfer lengths of prestressed beams cast with conventional-slump concrete has been performed, but very little has been done in regard to beams cast with self-consolidating concrete ...
The Effects of Sulfide on Pulp and Paper Wastewater Color Reversion
(2008-09-09)
More and more concern is being given to the aesthetics of wastewater, specifically the color of the resulting effluent. The underlying causes of colored wastewater suggest incomplete pollutant removal and unsuccessful ...
Determining the Optimum Compaction Level for Designing Stone Matrix Asphalt Mixtures
(2008-09-09)
As Stone matrix asphalt (SMA) becomes more widely used in the United States, there is a need to further refine its mix design procedure. Some states have found that 100 gyrations with the Superpave Gyratory Compactor (SGC) ...
Destruction of Perchlorate and Nitrate by Stabilized Zero-valent Iron Nanoparticles and Immobilization of Mercury by a New Class of Iron Sulfide Nanoparticles
(2008-09-09)
This research compares representative standard strong-base anion (SBA) and weak-base anion (WBA) exchangers, a bifunctional resin (A-530E), a class of polymeric ligand exchangers (PLE’s), and an ion-exchange fiber (IXF) ...
Analytical Solutions for Sequentially Coupled Multi-Species Reactive Transport Problems
(2008-09-09)
Multi-species reactive transport equations coupled through sorption and sequential first-order reactions are commonly used to model sites contaminated with radioactive wastes, chlorinated solvents and nitrogenous species. ...
Relationships Between Laboratory Measured Characteristics of HMA and Field Compactability
(2008-09-09)
Compactability of HMA mixtures is often used to describe how easy or difficult a mixture is to compact on a roadway. Several asphalt researchers have proposed laboratory measured parameters of mixtures and/or their ...
