A Laboratory Investigation Of The Properties Of Coal-Bitumen Paving Mixtures, Gary Grant Howard

Kentucky Transportation Center Research Report

The principal objective of this study was to investigate the feasibility of using coal, and to a lesser extent coal mine wastes, as aggregate in bituminous paving mixtures. These local aggregates were laboratory tested in bitumen-aggregate mixtures and, more particularly, in so-called cold-mixes. The bitumen-aggregate mixtures were evaluated by the Immersion-Compression Test, ASTM D 1075-60, with modifications for cold mixtures recommended in the Public Roads Journal (4).

In this initial study, since it was not possible to evaluate all types of mixtures, the primary question of whether coal and its waste products can be used as road aggregate could not …

Fourth Annual Performance Survey Of Reinforced Concrete Pipe Culverts, Ronald D. Hughes

Kentucky Transportation Center Research Report

A stylized, rational criterion for the structural design and installation of reinforced concrete pipe culverts was developed by the Bureau of Public Roads in cooperation with Prof. M. G. Spangler of Iowa State College and the American Concrete Pipe Association and was distributed to the various state highway agencies, April 4, 1957, as Circular Memorandum 22-40.* The criterion was intended to bring together and simplify methods for computing the strengths required for various fill heights and conditions of bedding. The several highway agencies were urged to adopt the criterion for use on all Federal-aid projects and accordingly, the Kentucky Department …

The Plastic Behavior Of Beams With Butt Welded Connections., Paul George Hayes

Masters Theses

"The purpose of this study is to determine the length of butt welds required to develop the full plastic section modulus of a 6 WF 20 rolled section of A-36 steel. The members were electric arc welded with LR 6070 electrodes. Two-point loading was used to develop a zone of pure moment with zero shear where these members were joined.

At the cross-section to be welded, all the flange edges were prepared to receive a single-vee butt weld and the webs were prepared for a double-vee butt weld. In all cases the full length of the flange was welded. However, …

Optimalization By Peak-Holding, Curtis W. Dodd

Masters Theses

"The problem presented is a study of the peak-holding method of optimalization. This method applies to a system that has an extremum.

After describing how the complete system, consisting of the controller and the controlled system, works; variations in the controller are presented. These variations are changes in the final stage of the controller, the servo. A phase-plane analysis shows how the output of the controlled system varies with its rate of change. Limitations are presented which tell why the system cannot be kept at its peak value at all times. Finally an analog simulation is used to study the …

Thermal Resistance Of Bonds And Contacts, David Marion Lewis

Masters Theses

"The adhesive and sealant Industry has more than kept pace with our rapidly expanding technology of today. This growth has left the standardization of data on adhesives far behind and lack of this data is obvious. Of the many applications, particularly as related to space technology and energy conversion, the resistance to the flow of heat offered by the bond layer is of considerable importance.

Little information is available on the effect of adhesives on heat transfer. In connection with their work on honeycomb panels, Rankle, Gier, and Bevans (7) determined the thermal resistance of the particular type of adhesives …

Compaction Characteristics Of Fine Grained Soils., Lewis Clyburn Sowell

Masters Theses

"The existing theories of compaction of soi Is are reviewed. The effect of varying the compactive effort on dry density, optimum moisture content, and compressive strength for three fine grained soils is investigated. These samples consist of si I ty clay (CL), plastic clay (CH), and loess (ML). The test results indicate that compactive effort has an important effect on the shape of the moisture density curve and that a potential for over compaction increases with a higher plastic index and c l ay content. At water contents above the Standard AASHO optimum value, the compressive strength is not appreciably …

A Determination Of The Theoretical Stresses In A Deep Beam., James William Tritz

Masters Theses

"This paper presents an analytical solution of the stress distribution in a deep beam of finite length. The beam being considered is analyzed as one of plane stress. The method employed superimposes two stress functions each of which is a trigonometric series. The first stress function satisfies all boundary conditions except that of zero stress on the vertical faces. The second function is found, so that, when combined with the first function, all boundary conditions are satisfied. The IBM 1620 digital computer is then used to find the stresses for a particular beam. The results of this analysis are then …

Effect Of Hydroxyethyl Cellulose On Properties Of Concrete At Early Ages., Vipinchandra R. Shah

Masters Theses

"In this investigation, hydroxyethyl cellulose was used as an admixture in plain concrete. The admixture was tested for its effect on the compressive strength of plain concrete cylinders and for its effect on the flexural strength of plain concrete beams. Specimens were also tested for freeze-thaw durability and shrinkage.

The test results indicated that hydroxyethyl cellulose has the effect of increasing the compressive strength and decreasing the flexural strength of plain concrete. The rapid freezing and thawing tests showed that the durability increases with increase in amount of admixture.

The tests were carried out in the Materials Laboratory of the …

Calibration Of Irrigation Headgates By Model Analysis, Gaylord V. Skogerboe, Vaughn E. Hansen

Reports

Introduction

The purpose of this research project was to calibrate the slide gates used by the D.M.A.D. Company (Delta, Melville, Abraham and Deseret Irrigation Companies). These gates, which number more than 600, are located throughout the distribution system. Each gate is placed in a concrete box 4 feet wide, 3-1/2 feet deep and 4 feet long. The structure is used as a means of diverting the water and is also used as a measuring device.

A similar structure, but with a different type of slide gate, was calibrated in 1914. At the time rating tables were prepared which listed the …
