Evaluation Of Geomembranes Using An Ultrasonic Method, Nazli Yesiller, Sevil Sungur

Civil and Environmental Engineering

An ultrasonic testing procedure was developed to evaluate geomembranes. The pulse-echo inspection technique was used on the surface of geomembranes without disturbing the material. The equipment required consists of a P-wave transducer, a pulser-receiver, and a signal acquisition system. Travel time of ultrasonic waves and waveform energy are measured to evaluate the condition of geomembranes. Laboratory tests were conducted to assess the effectiveness of the method. Defects that simulate installation damage and various in-service degradation conditions were induced on samples. The defects were identified with the ultrasonic method at a success rate higher than 98%. Changes in the thickness or …

Compressive Behavior Of Concrete With Vitrified Soil Aggregate, Shane M. Palmquist, Daniel C. Jansen, Christopher W. Swan

Civil and Environmental Engineering

The compressive behavior of portland cement concrete with vitrified soil coarse aggregate is the focus of this paper. A total of 10 batches of concrete were examined at four different coarse aggregate volume fractions with three different combinations of vitrified and natural coarse aggregates. For comparison purposes, the ratios of cement, water, and fine aggregates were held constant. The stress-strain curves, modulus of elasticity, compressive strength, and Poisson's ratio are examined as a function of coarse aggregate content. Results show a decrease in compressive strength as the volume fraction of vitrified soil aggregate increased. Moduli of elasticity for concrete with …

Simplified Analysis Of Asymmetric Structures With Supplemental Damping, Rakesh K. Goel

Civil and Environmental Engineering

This study investigated the effects of neglecting off‐diagonal terms of the transformed damping matrix on the seismic response of non‐proportionally damped asymmetric‐plan systems with the specific aim of identifying the range of system parameters for which this simplification can be used without introducing significant errors in the response. For this purpose, a procedure is presented in which modal damping ratios computed by neglecting off‐diagonal terms of the transformed damping matrix are used in the traditional modal analysis. The effects of the simplification are evaluated first by comparing the aforementioned modal damping ratios with the apparent damping ratios obtained from the …

Watershed Management Technique To Control Sediment Yield In Agriculturally Dominated Areas, John W. Nicklow, Misgana K. Muleta

Civil and Environmental Engineering

Non-point source pollution is recognized internationally as a critical environmental problem. In Illinois, soil erosion from agricultural lands is the major source of such pollution. The erosion process, which has been accelerated by human activity, tends to reduce crop productivity and leads to subsequent problems from deposition on farmlands and in water bodies. Comprehensive watershed management, however, can be used to protect these natural resources. In this study, a discrete time optimal control methodology and computational model are developed for determining land use and management alternatives that minimize sediment yield from agriculturally-dominated watersheds.

Ascent And Decompression Of Viscous Vesicular Magma In A Volcanic Conduit, Helene Massol, Claude Jaupart, Darrell Pepper

Mechanical Engineering Faculty Research

During eruption, lava domes and flows may become unstable and generate dangerous explosions. Fossil lava-filled eruption conduits and ancient lava flows are often characterized by complex internal variations of gas content. These observations indicate a need for accurate predictions of the distribution of gas content and bubble pressure in an eruption conduit. Bubbly magma behaves as a compressible viscous liquid involving three different pressures: those of the gas and magma phases, and that of the exterior. To solve for these three different pressures, one must account for expansion in all directions and hence for both horizontal and vertical velocity components. …

Development Of Concrete Qc/Qa Specifications For Highway Construction In Kentucky, Kamyar C. Mahboub, Donn E. Hancher

Kentucky Transportation Center Research Report

There is a growing trend toward quality-based specifications in highway construction. A large number of quality control/quality assurance (QC/QA) specifications shift the responsibility of day-to-day testing from the state DOH to the contractor. This requirement for contractor-performed quality control testing has been partly due to the fact that state agencies are operating with a smaller pool of employees compared to previous years. Another driving force has been the application of performance-based specifications and realization that the contractor and the producer need some degree of flexibility in order to be more efficient and innovative. This report presents the background information behind …

Biotransformation Of Various Substituted Aromatic Compounds To Chiral Dihydrodihydroxy Derivatives, Henning Raschke, Michael Meier, Roland Hany, Markus D. Muller, Jan Roelof Van Der Meer, Hans-Peter E. Kohler, Joel Gerard Burken

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The biotransformation of four different classes of aromatic compounds by the Escherichia coli strain DH5α(pTCB 144), which contained the chlorobenzene dioxygenase (CDO) from Pseudomonas sp. strain P51, was examined. CDO oxidized biphenyl as well as monochlorobiphenyls to the corresponding cis-2,3-dihydro-2,3-dihydroxy derivatives, whereby oxidation occurred on the unsubstituted ring. No higher substituted biphenyls were oxidized. The absolute configurations of several monosubstituted cis-benzene dihydrodiols formed by CDO were determined. All had an S configuration at the carbon atom in meta position to the substituent on the benzene nucleus. with one exception, the enantiomeric excess of several 1,4-disubstituted cis-benzene dihydrodiols formed by CDO …

In-Situ Colloidal Mno2 Deposition And Ozonation Of 2,4-Dinitrotoluene, Kevin C. Bower, Kevin H. Gardner, Christopher M. Miller, Lingjun Kong

Civil & Environmental Engineering

Laboratory experiments are presented that demonstrate a novel in situ semipassive reactive barrier for the degradation of 2,4 dinitrotoluene created by coating aquifer surfaces by deposition of colloidal MnO2, which catalyzes ozone degradation and enhances contaminant oxidation. Ozone is added to the reactive barrier and is transported through the zone with the contaminants by existing hydraulic gradients. The communication presents the preliminary laboratory investigation demonstrating the viability of this method. Studies were conducted by coating Ottawa sand with colloidal MnO2. Results show that concentrations of MnO2 in the range of 0.2 mg/g can be deposited with no measurable change in …

Development And Proposed Implementation Of A Field Permeability Test For Asphalt Concrete, David L. Allen, David B. Schultz Jr., L. John Fleckenstein

Kentucky Transportation Center Research Report

Pavement drainage contributes greatly to long-term pavement performance. Pavements undergo surface, as well as subsurface, drainage during prolonged rain events. It is this subsurface drainage that is of concern in this study. In the advanced asphalt pavements of today, where a drainage layer may be incorporated to facilitate the movement of water out of the above overlying pavement layers, water can be a problem in areas with variable permeability. High permeability may also cause other problems related to drainage such as frost heave, stripping, asphalt emulsification, and water coming out of the pavement surface from deeper layers in the pavement …
