Assessing Performance Characteristics of Sediment Basins Constructed in Franklin County, Alabama
(2012-11-12)
The objective of the research project was to monitor the performance of newly designed sediment basins that were constructed on the ALDOT 502 project in Franklin County. The project included four tasks: (1) assess performance ...
Assessment of Design Provisions for Open I-Section under Combined Flexure and Torsion
(2012-07-02)
In civil structures, the members often encounter a combined loading of flexure and torsion, which has a strong influence on the members’ behavior and capacity, especially for those beam sections with relatively weak torsional ...
Assessment of Stability Test Methods for Self-Consolidating Concrete
(2011-04-01)
Self-consolidating concrete (SCC) is a highly fluid, nonsegregating concrete that can spread through reinforcement and completely fill formwork without the use of mechanical consolidation. Resistance to segregation, also ...
Assessment of Storm Water Quality through Porous Pavement Systems
(2015-07-31)
Stakeholders, (designers, industrial developers, governmental agencies, and private landowners) are increasingly concerned about enhancing storm water quality, reducing run off, and improving the recharge of ground water. ...
Assessment of the Coefficient of Thermal Expansion of Alabama Concrete
(2008-12-15)
The coefficient of thermal expansion (CTE) is a fundamental property of portland cement concrete. It represents the change in unit length of concrete per degree of temperature change. The CTE is a very important property ...
Assessment of the effects of soil amendments on the leaching of lead and arsenic from contaminated soil
(2006-12-15)
Lead has a long history in the life of human beings. Unfortunately, only recently did people start to realize that lead is a toxin. Because of increasing human activity, soil lead pollution has become a serious environmental ...
An Assessment of U(VI) Adsorption at Multiple Scales
(2010-10-21)
Iron (III) (oxyhydr)oxide coatings on soils and sediments are one of the most important factors in controlling the adsorption and transport of U(VI) in the subsurface. In this study, iron-coated sands were prepared via two ...
Automated Screening Tool for the Stability of Highway Bridges Subject to Scour
(2008-05-15)
Most bridges in Alabama that are over shallow bodies of water, including small creeks, wetlands, and marshes, were designed so that the bridge superstructure is supported on pile bents. During major flood events, excessive ...
Behavior of a Damaged Prestressed Concrete Bridge Repaired with Fiber-Reinforced Polymer Reinforcement
(2011-08-08)
After the construction of elevated portions of I-565 in Huntsville, Alabama, cracks were discovered in numerous prestressed concrete bulb-tee bridge girders that were constructed to exhibit continuous behavior in response ...
Behavioral, Operational and Safety Effects of Red-Light Cameras at Signalized Intersections in Alabama
(2016-11-02)
Statistics reveal that from 2007-2011 an average of 751 people died each year in red-light running (RLR) crashes in the U.S. Past studies showed that red light cameras (RLCs), as an enforcement countermeasure, can lower ...
A Benefit/Cost Analysis of Paved Shoulder Installation on High Priority Road Segments on Two-Lane Rural Highways in Alabama
(2008-08-15)
There are currently more than 40,000 deaths a year that occur as the result of motor vehicle traffic accidents, which have been ranked among the leading causes of death for Americans. In addition, a reported 55% of all ...
Biodecolorization of Paper Mills Wastewater Using Anaerobic Composting
(2009-08-04)
This research studied the feasibility of using anaerobic composting for decolorizing effluents in the pulp and paper industry. While color is regarded as an aesthetic problem, there are several adverse effects associated ...
Biopolymers for enhancing the engineering properties of soil
(2020-05-12)
The need for constant construction rapidly expands the built environment which often spreads over areas with unfavorable site conditions. In such events, soil stabilization is an inevitable process. Increasing soil strength ...
Bond Behavior of Prestressed Reinforcement in Beams Constructed with Self-Consolidating Concrete
(2007-05-15)
Accurate behavioral characteristics of self-consolidating concrete (SCC) should be
established prior to its widespread implementation in prestressed members. This thesis
describes an investigation of bond behavior of ...
Braking Forces in Highway Bridge Substructures
(2019-06-24)
Under the Load-and-Resistance Factor Design Specification, the longitudinal braking force that must be designed for was increased when compared to a bridge designed according to the previous code, the Standard Specification. ...
Breaching of Concrete Masonry Unit Walls due to Direst Shear when Subjected to Blast Loading
(2012-04-10)
This report details the steps needed to formulate an engineering design equation to address the potential for breaching of concrete masonry walls in between grout cells when subjected to blast loading. Prior to the beginning ...
Bridge Pile Bent P-Delta Curves in Transverse Direction Using FB-Pier and GTSTRUDL Pushover Analysis Procedures
(2005-08-15)
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 ...
Calibration of Fatigue Transfer Functions for Mechanistic-Empirical Flexible Pavement Design
(2005-12-15)
As agencies continue to adopt mechanistic-empirical (M-E) pavement design, the need for locally calibrated transfer functions will continue to increase. Transfer functions are the critical link from mechanical pavement ...
