Lead Binding To Metal Oxide And Organic Phases Of Natural Aquatic Biofilms, Yarrow M. Nelson, Leonard W. Lion, Michael L. Shuler, William C. Ghiorse
Civil and Environmental Engineering
The role of the composition of surface-coating materials in controlling trace metal adsorption in aquatic environments was investigated using natural biofilms that developed on glass slides in three New York State lakes and a water-supply well. Adsorption isotherms were obtained for Pb binding to each of the biofilms in solutions with defined Pb speciation at 25°C and pH 6.0, with Pb concentrations ranging from 0.2 to 2.0 μM. Adsorption isotherms for Pb binding to laboratory-derived metal oxides and surrogate organic materials were determined under the same conditions. These isotherms, combined with characterization of natural biofilm composition, were used to estimate …
Capacity‐Demand‐Diagram Methods Based On Inelastic Design Spectrum, Anil K. Chopra, Rakesh K. Goel
Capacity‐Demand‐Diagram Methods Based On Inelastic Design Spectrum, Anil K. Chopra, Rakesh K. Goel
Civil and Environmental Engineering
An improved capacity‐demand‐diagram method that uses the well‐known constant‐ductility design spectrum for the demand diagram is developed and illustrated by examples. This method estimates the deformation of inelastic SDF systems consistent with the selected inelastic design spectrum, while retaining the attraction of graphical implementation of the ATC‐40 Nonlinear Static Procedure. One version of the improved method is graphically similar to ATC‐40 Procedure A whereas the second version is graphically similar to ATC‐40 Procedure B. However, the improved procedures differ from ATC‐40 procedures in one important sense. The demand diagram used is different: the constant‐ductility demand diagram for inelastic systems …
Investigation Of Feasible Pavement Design Alternatives For Wisdot, James Crovetti, Sam Owusu-Ababio
Investigation Of Feasible Pavement Design Alternatives For Wisdot, James Crovetti, Sam Owusu-Ababio
Transportation Research Center: Feasible Pavement Design Alternatives
The current pavement design and selection process of WisDOT for all new pavements or reconstructions of existing pavement structures provides for the design of one asphaltic concrete (AC) and one portland cement concrete (PCC) pavement alternative. Life-cycle costs analyses are then used to determine the preferred alternative for construction. Previous restrictions in the WisDOT pavement selection process have essentially excluded the construction of thick AC (AC thickness > 150 mm) and thin PCC (PCC thickness < 225 mm) pavements and thus the validity of current life-cycle cost inputs for these pavement types is under question.
This report presents a performance analysis of existing thick AC and thin PCC pavements constructed in and around Wisconsin. The performance trends developed indicate current design …

Evaluation Of Superpave In Kentucky, L. John Fleckenstein, David L. Allen, Richard Reitenour
Evaluation Of Superpave In Kentucky, L. John Fleckenstein, David L. Allen, Richard Reitenour
Kentucky Transportation Center Research Report
Approximately 93 percent of all pavements in the United States are surfaced with hot-mix asphalt (HMA). For many decades, most asphalt pavements were designed using the Marshall mix design method. In 1987, the Strategic Highway Research Program was established with 50 million dollars being allocated for asphalt pavement research. From that research, a new asphalt mix design procedure, called Superpave, was developed. Many states have adopted, or are in the process of adopting, this procedure, including Kentucky. In 1995, Kentucky placed its first Superpave mixture on KY 676 in Franklin County. In 1998, the Kentucky Transportation Cabinet requested that the …

Economic Impact Of Heavy Loads On The Highway Infrastructure, Brad W. Rister, R. Clark Graves, David L. Allen
Kentucky Transportation Center Research Report
During the 1986 General Assembly the Extended-Weight Coal Haul Road System was created by the Kentucky State Legislature. This system was defined to include those highways where more than 50,000 tons of coal had been hauled during the previous year. Trucks hauling coal on the extended-weight system were authorized to exceed the normal weights limits through the payment of an annual decal fee.
In efforts to identify the benefactors of the extended coal haul system legislation, this study has been conducted to identify the overall economic impact of hauling heavier total gross weights by coal truck on the highway infrastructure …
Correlation Of Rock Quality Designation And Rock Scour Around Bridge Piers And Abutments Founded On Rock, Tommy C. Hopkins, Tony L. Beckham
Correlation Of Rock Quality Designation And Rock Scour Around Bridge Piers And Abutments Founded On Rock, Tommy C. Hopkins, Tony L. Beckham
Kentucky Transportation Center Research Report
Local scour around the base of a bridge pier or abutment occurs as the result of flow acceleration around the obstruction, formation of a vertical pressure gradient along the upstream end, and generation of vortices at the base of the structure. The flow patterns around piers and abutments are complex in detail, and the complexity increases as a scour hole forms in the bed around the structures. The potential for local scour at a bridge pier or abutment needs to be estimated so that foundations can be designed to resist failure during large floods. While procedures have been suggested for …

Cost Effective Concrete Pavement Cross Sections - Interim Report, James Crovetti
Cost Effective Concrete Pavement Cross Sections - Interim Report, James Crovetti
Transportation Reports with the Wisconsin Department of Transportation
The present pavement selection policy of the Wisconsin Department of Transportation (WisDOT) limits the design alternatives for Portland Cement Concrete (PCC) pavements and inhibits the designer's ability to select cross-sections deviating from uniform slab thicknesses with doweled transverse joints. Currently, uniform slab thicknesses and conventional joint load transfer devices are incorporated into the design based on the heavy truck traffic in the outer lane. While this strategy provides for adequate pavement structure in this truck lane to limit faulting and slab cracking to tolerable levels, there is a potential for over-design in other traffic lanes which receive significantly lower Equivalent …

The objectives of this study were to first evaluate the existing traffic conditions along the NE part of New Circle Road and investigate the use of unconventional left turn treatments, as well as other access restrictions to improve the operating conditions of New Circle Road. The alternatives examined include a do-nothing alternative, the addition of one through lane per direction, the use of median U-turns at various locations, and combinations of them. Restrictive left turn strategies proved to be a more successful tool for traffic management on New Circle Road than simply adding a lane in each direction. Using median …
Optimal Design Of Aquifer Clean Up Systems Under Uncertainty Using A Neural Network And A Genetic Algorithm, Alaa H. Aly, Richard C. Peralta
Optimal Design Of Aquifer Clean Up Systems Under Uncertainty Using A Neural Network And A Genetic Algorithm, Alaa H. Aly, Richard C. Peralta
Civil and Environmental Engineering Faculty Publications
We present a methodology to account for the stochastic nature of hydraulic conductivity during the design of pump-and-treat systems for aquifer cleanup. The methodology (1) uses a genetic algorithm to find the global optimal solution and (2) incorporates a neural network to model the response surface within the genetic algorithm. We apply the methodology for a real example and different optimization scenarios. The employed optimization formulation requires few hydraulic conductivity realizations. The presented approach produces a trade-off curve between reliability and treatment facility size .
