A Study Of Runoff From Small Drainage Areas And The Openings In Attendant Drainage Structures, Eugene M. West, J. O. Cornell

Kentucky Transportation Center Research Report

In 1926, John T. Lynch read to the Kentucky Academy of Sciences a paper entitled, "The Relation Between Drainage Area and Waterway Required for Culverts and Small Bridges in Kentucky." The paper was based on a study of many small drainage structures then existing in the highway system, and a general evaluation of the performance of the structures in relation to rainfall and runoff from contributing watersheds.

As a result of this report, and in accordance with the suggestions contained in it, the Department of Highways adopted a system of runoff coefficients applicable to different sections of the state and …

A Test Road For The Evaluation Of Sandstone As An Aggregate In Plant-Mix Bituminous Pavements, Ellis G. Williams

Kentucky Transportation Center Research Report

In eastern Kentucky, deep deposits of sandstones and shales overlie the vast deposits of limestones that prevail throughout the central part of the state. Whereas locally available limestones of high quality comprise the major sources of crushed stone or aggregate for highway paving in the central part of the state, some areas of eastern Kentucky are so far removed from sources of these and other high-type aggregates that transportation of materials becomes a major cost item. It is a matter of record that these costs frequently approach or even exceed the cost of the material at the source, Since aggregate …

An Early Tertiary Stream Channel Between Fish And Pipestone Creeks, Ten Miles West Of Whitehall, Montana, Henry D. Olson

Bachelors Theses and Reports, 1928 - 1970

Driving between Butte, and Whitehall, Montana, on highway U.S. 10S, one observes an interesting phenomenon in the lower end of Little Pipestone Creek canyon. One side and the bottom of the canyon is cut inthe hard igneous rocks of the Boulder Batholith, and the other side of the canyon is made of unconsoli­dated sand, gravel, and cobbles.

Methods Of Routing Floods Through Reservoirs, Rowland W. Fife

Civil Engineering ETDs

Flood routing through reservoirs serves several major functions. It makes possible the determination of the effect of a reservoir, whether constructed for flood control purposes alone or for other purposes, on historic or predicated future floods at the reservoir site. The effect at the dam site then provides a basis for calculating the effect downstream. It also aids in obtaining the proper manipulation of gated spillways on multiple purpose reservoirs to provide the most advantageous flood control on the stream and at the same time make the best use of the water for power, irrigation, or other purposes.

A Bank Gravel Base Containing Calcium Chloride [Report No. 1], William B. Drake

Kentucky Transportation Center Research Report

This report is concerned with a bank gravel base construction project, and particularly with that part of the base containing calcium chloride as a stabilizing agent. The project was carried out on a relocation of U.S. 62, between Kuttawa in Lyon County and Kentucky Dam on the Tennessee River. A part of the project, as shown on the general location map in Fig. 1, was in Livingston County between the Cumberland and Tennessee Rivers.

Correlation Of The Model And Prototype Tests Of The Conchas Dam Service Spillway And Stilling Basin, Geary W. Allen Jr.

Civil Engineering ETDs

Conchas Dam and Reservoir, one of the largest water resources projects in the Southwest, build under the supervision of Corps of Engineers, is located below the confluence of the Conchas River and South Canadian River, near Tucumcari, New Mexico. Although it is the source of water supply for the vast Tucumcari Irrigation Project of the U.S. Bureau of Reclamation, its main purpose is flood control. Conchas Dam exerts a tremendous influence on the economy of the northeastern portion of Texas. To a hydraulic engineer its large size and complex hydraulic features present a most challenging field for study and research

2. That welded wire fabric provides adequate crack control within the working limits of the fabric.

In order to efficiently accomplish Objectives 1 and 2 above, we wish to establish:

1. The safe working stress that we can safely recommend for welded wire fabric -- both in bond and tension.
2. The proper spacing of longitudinal …

An Investigation As To The Uses Of The Topographic Map And Improvements Desired By The General Public, George O. Boeckman

Masters Theses

"The demand for topographic maps from hunters, fishermen, vacationers, professional engineers etc, has been increasing with each passing year. In 1940 people bought some 700,000 copies of topographic maps. In 1946 sales had jumped to well over 2,000,000 copies. Civilian use of these maps by veterans has contributed substantially to the tremendous expansion of demand for maps since World War II. In recent years, the quality of topographic maps has been greatly improved by refinements in methods and by the use of aerial photography in map compilation. This advancement, and an ever-increasing demand from engineers, geologists, and many others for …

"After due consideration of the facts and hypothetical conditions enumerated herein, it was decided that this work would be devoted to developing a means of determining the most economical “C” factor to be used; one that will be consistent with ease of operating the plotting machine, the required accuracy of the finished compilation and economy. In other words, the highest value of the "C" factor that will produce results within the accuracy requirements under normal operating procedures.

As a secondary project, it was decided to plot a curve using points determined by analyzing a series of spot readings made at …

Hydrology Of Small Drainage Areas, James Kinchen Searcy

Masters Theses

"Realizing the need for data on small drainage areas the Missouri Highway Commission in 1947 began a cooperative project with the Water Resources Division of the United States Geological Survey which includes the establishment of small area gaging stations and recording rain gages.

The purpose of this investigation is to study some of the data collected in the few years of operation of these small area stations with the aim of testing some of the hydrologic tools useful in the study of larger drainage basins to determine their applicability on small drainage basins. The relationship between the runoff of large …

An Investigation Of End-Anchorage And Performance Of Sr-4 Strain Gages On A Prestressed Concrete Beam, Howard W. Nunez Jr.

Masters Theses

"In recent years there has been brought to the attention of engineers and architects a new medium of construction---prestressed concrete. Reinforced concrete has long been recognized as a satisfactory material for use in the construction of buildings, bridges, highways, tanks and other structures. However, most concrete designers will concede that this material has many drawbacks. For instance, in a simple beam of rectangular cross-section, roughly only one half or the concrete is relied on to resist compressive forces. The tensile strength of the concrete is considered to be zero, and steel bars or rods must be inserted to carry the …

The Effect Of Grain Size On Shearing Strength Of Sand, Keyhan Samimi

Masters Theses

"The object of this study is to determine experimentally the effect of definite grain size on the shearing characteristics of sandy soils. As it will be discussed in detail under the article - The Mechanics of Shear, the shearing characteristics of sandy soils depends on many factors such as grain size and shape, soil structure and relative density, the water content of soil. An attempt is made throughout the entire investigation to determine the effect of definite grain size on the shearing value and the angle of internal friction under the dry and saturated conditions. Furthermore, the results of shear …

Comparative Study Of The Physical Properties Of Traffic Paints, A. C. Peed Jr.

Kentucky Transportation Center Research Report

Traffic or zone paints have become a major item of expenditure for highway departments with their increasing mileages and with the increase in traffic using the highways. Extending the mileage requiring marking and increasing the traffic wear on the marking has necessitated successively larger purchases of paint and associated equipment. As this market became larger increasing numbers of manufacturers have entered the field with a great diversity of formulations having differing properties.

In order to bring some order out of this situation the Research Laboratory in cooperation with the Division of Traffic undertook a study of the paints as offered …

During the 1950 construction season the Research Division observed the construction of several types of seal coats, a few tack coats and a penetration macadam pavement, A report, covering mostly construction practices on these projects, was submitted to the Research Committee at the February meeting in 1951. The report is titled "Observations on Seal Coats, Tack Coats, and Penetration Macadam Construction in 1950," and dated January, 1951.

A follow-up of most of these projects is submitted here, The performance of the seals was greatly influenced by failure of the bases during the very severe winter of 1950-51. Considerable frost action …

Spherical Lens Optics Applied To Retro-Directive Reflection, James H. Havens, Allie C. Peed Jr.

Kentucky Transportation Center Research Report

This paper describes some expedient applications of elementary optical principles to the evaluation of glass-bead reflectorizing systems for highway signs and markers. 'The optical function of spherical lenses in achieving reflex-reflection is illustrated both photographically and diagrammatically. Various optical designs are discussed and analyzed. By simple geometric optics, the efficiency of these systems is correlated with the practical performance criteria for retro-directive reflectorization.

Clay Mineralogy And Soil Stabilization, James H. Havens, William A. Goodwin

Kentucky Transportation Center Research Report

This paper attempts to resolve a general concept of soil rheology from the standpoint of clay mineralogy, ion-exchange, properties of clay-water systems, and volume relationships existing between clay-water systems and granular structures. Both theory and experimental data are presented.

In the experimental phase, synthetic soils of varying clay contents were prepared from carefully fractionated soil constituents. These were subjected to combined-stress analyses, tests for plasticity characteristics, and detenninations of other physical properties.

Evaluation Of Plant Mix Surface Treatments, William B. Drake

Kentucky Transportation Center Research Report

This project made use of six bituminous materials and ten aggregate gradations in plant mix paving operations. The test sections were installed by state forces in 1942 and 1943. The object was to determine which aggregate gradation with a specific bituminous material was best suited for an application of 75 pounds per square yard surface treatment.

The bituminous materials used were MC-5, RC-5, RT-12, PAC-5 (85 to 100 penetration), PAC-7 (120 to 150 penetration), and PAC-8 (150 to 200 penetration). Twenty sections of MC-5 and ten sections of RC-5 were laid in 1942; all the sections containing the other materials …

Microfauna Of The Colorado Shale In The Sunburst Dome Area, Montana, Merle W. Emmert

Bachelors Theses and Reports, 1928 - 1970

It has been hoped that a micropaleontological study of the shales of the Upper Cretaceous Colorado Group in northern Montana would reveal certain faunal zones which would serve as markers in an otherwise drab, undifferentiated, 1800 feet of grey, fissile shale. This paper presents the results of a study of the microfauna in certain samples from this shale in the Sunburst Dome area north of Shelby, Montana.

The Elkhorn Mine Of Jefferson County, Montana, David D. Walker

Bachelors Theses and Reports, 1928 - 1970

In 1901, after yielding metals valued in excess of five million dollars, it was considered worked out. Since that time the mine has passed through the hands of several own­ers, none of whom have failed to realize a profit from it. Although at no time since its zenith did it ever regain its once great production, it did provide a livelihood for those who worked it. Now with the American Smelting and Refining Company interested in it, perhaps it will once again become an important producer.

The Occurrences Of Non-Metallic Minerals In Montana, Samuel T. Mitchell

Bachelors Theses and Reports, 1928 - 1970
