Large-Stone Mixes For Reducing Rutting, Kamyar C. Mahboub

Kentucky Transportation Center Research Report

Large-stone mixes are becoming a very popular means for reducing rutting in flexible pavements. Aggregate interlock in large-stone mixes provides for very efficient dissipation of compressive and shear stresses that are known to be responsible for rutting and shoving in flexible pavements. This report documents mix design procedures and laboratory testing for characterization of rutting potential of large-stone asphalt mixes (LSAM) in Kentucky and particularly the Louisa Bypass project.

A series of large-stone aggregate gradations were studied. A promising aggregate gradation was selected in cooperation with Kentucky Department of Highway officials and representatives of the asphalt industry. Based upon the …

Investigation Of Flow Patterns In Various Wastewater Treatment Facilities, Thomas Joseph Martin Jr

LSU Historical Dissertations and Theses

The theoretical hydraulic retention time of wastewater treatment plants is often used to predict the efficiency of treatment and to calculate operational parameters. However, these values are related to the actual hydraulic retention time. When there is a large discrepancy between the actual and predicted values, the actual hydraulic retention time can be determined by marking a parcel of wastewater and recording its passage through the system. This investigation utilized rhodamine WT, a fluorescent dye, to track the movement of wastewater through a stabilization lagoon and a rock-reed filter. The loss of rhodamine WT to sorption, biodegradation and photodegradation was …

Variations Of Alkalinity, Ph, Oxidation Reduction Potential, And Conductivity In Single And Multi-Stage Sludge Digestion Systems, Nasser M. Kamazani

Theses

Anaerobic digestion is used at many municipal and industrial wastewater treatment plants. Recent increase in the cost of energy and search for an alternative source of energy for the future have prompted renewed interest in anaerobic digestion for energy recovery by production of methane from waste materials, including wastewater sludges and agricultural and municipal solid wastes. Accordingly, a large literature exist on the subject, most of it dealing with more physical aspects of different process design. Little or not enough attention has been paid to its highly complex biochemical characteristics.

The purpose of this study is a preliminary investigation regarding …

Mobile Deployable Bases And Ports: A Study For Interim Requirements, William Glenn Moore

Marine Affairs Theses and Major Papers

Logistics is an age old problem that has been the key to the greatest victories and defeats in history. Maritime support of wartime land campaigns as well as conflicts at sea, has been the answer to that problem even as far back in history as the ancient Greek Empire. Throughout the ages however the lesson that seems to be learned and relearned, the hard way, is that of logistic support. Today the United States is faced with what, to some seems to be an overwhelming problem in logistic support overseas, particularly in the maritime transportation and support arena. The U.S. …

Load And Resistance Factor Design Of Cold-Formed Stainless Steel Statistical Analysis Of Material Properties And Development Of The Lrfd Provisions, Shin-Hua Lin, Wei-Wen Yu, Theodore V. Galambos

CCFSS Library (1939 - present)

INTRODUCTION 1.1 General Remarks The "Allowable Stress Design" method has long been used for the design of steel structures in the United States. 1,2,3 Recently, the probability-based load and resistance factor design (LRFD) criteria have been successfully applied to the structural design of hot-rolled steel shapes and built-up members. 4,5,6 The AISI LRFD Specification is being developed as well for the design of structural members cold-formed from carbon and low alloy steels. 7-17 These design criteria can provide a more uniform degree of structural safety to achieve consistent reliability for different design situations. The probability-based design method is developed on …

Effects Of Collapse Settlement Of Fill On Reinforced Earth Walls, G. E. Blight

International Conference on Case Histories in Geotechnical Engineering

Two case histories illustrate the effects that collapse settlement of the fill forming a Reinforced Earth wall can have on the structure. Pre-requisites for collapse settlement are inadequate compaction, compaction at too low a water content, or a combination of these. Collapse settlement occurs subsequently when the water content of the fill is increased by infiltration. The effects of collapse settlement identified in this paper are: (i) a temporary release of friction on the reinforcing strips with the result that the wall facing moves outwards; and (ii) relative settlement between the fill and the wall facing with the result that …

Foundation Failures Associated With Salt Rock And Surrounding Coastal Plain, A. Orhan Erol, Abdulmohsin W. Dhowian

International Conference on Case Histories in Geotechnical Engineering

A detailed investigation has been conducted to study the causes of severe and widespread damages in a town situated on a salt dome. The study includes a thorough assessment of ground conditions in the coastal plain surrounding the salt dome for possible utilization of the plain as redevelopment areas. Major geological features in the study area comprised of collapsible windblown sands which are underlain by salt rock in the old town and soft/loose sabkha deposits in the proposed redevelopment zones. It has been found that the extensive damages in the buildings and roads are primarily due to subsidence phenomenon associated …

Geotechnical Investigation Into Causes Of Failure Of A Gabion Retaining Wall, Edward A. Nowatzki, Brian P. Wrench

International Conference on Case Histories in Geotechnical Engineering

This paper describes the post-failure analysis of a 26m long x 4m high gabion retaining wall located in a suburb of Johannesburg, South Africa. The wall had been built just beyond the toe of a natural slope with most of the gabion units resting on the bed of a small river. The river bed soils consisted of approximately 2.5 m of soft, dark-grey, silty clay underlain by massive granite bedrock. The water table at the toe of the wall was within 0.1 m of the river bed surface. Failure of the wall occurred over the weekend after backfilling to grade …

The Influence Of Thin Clay Layers On The Design And Performance Of A Flexible Cantilever Retaining Wall, R. Cameron, C. A. Carr

International Conference on Case Histories in Geotechnical Engineering

This case study presents the methods that were used successfully to redesign and monitor the performance of a flexible cantilever retaining wall, incorporating an in situ support berm, at a site where thin, weak clay layers were detected in the foundation during construction. A potential mode of failure termed "berm-block sliding", where the retaining wall pushes out the entire support berm as a block along the clay layers, governed the design analysis. Evidence of presheared planes within the clay layers required that the design shear strength parameters be based on residual values. The clay had a significant cohesion component which …

Construction Of Road Embankments Over Very Soft Soil Using Band Drains And Preloading, John D. Nelson, Brian P. Wrench

International Conference on Case Histories in Geotechnical Engineering

As part of a new national road being constructed in South Africa an embankment was built over a deep deposit of very soft soil. To enhance stability the embankment was built in several stages and in order to reduce the time required for consolidation between stages, band drains were installed in the foundation soils. The soils were instrumented to monitor pore water pressure and settlement. The results of the monitoring phase showed that the band drains were effective and operated as designed. This paper presents the results of the monitoring and discusses the prediction of degree of consolidation from settlement …

Correlation Between The Actual And Predicted Settlements Of Structures At Nsukka, Nigeria, H. O. Chukweze

International Conference on Case Histories in Geotechnical Engineering

The paper compares the measured and calculated settlements of two buildings and one concrete water tank founded on the red-weathered soils of Nsukka, Nigeria. Prior to actual construction of the structures the three sites were investigated, soil samples were collected and tested in the laboratory and the data collected were used to predict the total and differential settlements of the structures. Then permanent concrete slabs were established as bases at each of the three sites for observing other points. The theodolite was used at each of the sites to monitor the movements of each of the structures, starting from the …
