Evaluation Of Sprinkler Systems In Northern Utah, Murray J. Gavel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sprinkling as a method of irrigation has been expanding rapidly in the United States, with acreages irrigated by this method increasing every year. One of the major reasons for the expansion is the great improvements that have been made in sprinkler irrigation equipment. Light weight aluminum pipe, with quick couplers, improved pump and motor efficiencies have all made sprinkler irrigation more desirable. High efficiency of water application, labor requirements, and favorable plant response have also favored the expansion.

Another reason for the increase in sprinkler irrigation is that new lands being brought under irrigation are often not adaptable to surface …

Performance Of Kentucky (Natural Sandstone) Rock Asphalt, James H. Havens, Ellis G. Williams

Kentucky Transportation Center Research Report

Since about 1948, the performance of natural rock asphalt, used extensively in Kentucky and Indiana, has been plagued by a unique type of scaling in the wheel tracks of each traffic lane. This scaling has been typically an eighth to a quarter of an inch thick and has left the pavements rough and unsightly. In some cases, this phenomen has occurred several times in the same place and has caused much deeper rutting. The general condition is illustrated in a series of photographs attached hereto.

Measurement Of Irrigation Water, Eldon M. Stock

Reports

Foreword: Although irrigation has been practiced in Utah for more than one hundred years, irrigation water still is being distributed to farmers with little or not thought about its measurement. A farmer would not think of buying or selling other farm commodities, such as hay, grain, beef cattle, or dairy products, without weighing or accurately measuring them, but at the same time he is often content to accept and pay for the irrigation water received with little or no knowledge as to the actual amount received, or whether or not he is receiving the amount he is entitled to. Measurement …

Observations On The Constitution And Characterization Of Paving Asphalts, James H. Havens, W. F. Daniels

Kentucky Transportation Center Research Report

This paper contains results of analyses with asphalts of various composition and derivation. The objective of the study is to define and correlate constitution and fundamental character of asphalts in a manner significant to their use in highway pavements.

Further confirmation of the existence of three discrete solubility fractions in asphalts was obtained by extraction methods and by paper partition chromatography. Paraffin bodies were revealed by microscopic examination of thin films. Asphaltene fractions showed the presence of particulate material by electron microscopy and also revealed indications of peptized asphaltene bodies. Oils dialyzed from asphalt exhibited u.v. fluorescence similar to components …

Guides to Manuscript Collections

This collection consists primarily of the diaries of Samuel Roy Jenkins, written from 1887 until 1941. The early diaries, written between 1887 and 1898, deal with his life as a student at Grafton High School and West Virginia University, and later as a civil engineer in Grafton, West Virginia. The middle group of diaries cover the years from 1906 until 1925; Mr. Jenkins' floral business in Grafton and his increasing financial difficulties are the subjects of many of these entries. In the last group of diaries, written between 1930 and 1941, the entries discuss Mr. Jenkins' return to the engineering …

Triaxial Acceleration Analysis Applied To The Evaluation Of Pavement Riding Qualities, L. E. Gregg, William S. Foy

Kentucky Transportation Center Research Report

Traditionally the riding qualities of a pavement are expressed as some function of localized irregularities in the contour of the pavement surface. This is predicated on the fact that the portion of passenger comfort or discomfort imparted by all features of the pavement surface can not be isolated and determined separately from other influences such as vehicle characteristics or psychological and physiological aspects of the passenger himself.

Measurements of riding qualities have dealt almost exclusively with vehicle displacements in the vertical direction only, these having been and still being the most prominent and most amenable to measurement. By this procedure …

Application Of Wire Mesh Reinforcement To Asphaltic Concrete Pavement Overlays, Ellis G. Williams

Kentucky Transportation Center Research Report

In response to suggestions from the Wire Reinforcement Institute, the Department established during the past construction season some test sections to investigate wire mesh reinforcement in bituminous concrete. As in the case of most similar projects in other states, the intent was to determine the effectiveness of wire mesh for controlling "reflection cracking" in bituminous overlays placed on existing portland cement concrete pavement.

An Investigation Of The Binding Properties Of Limestone Dust, William E. Howard, Ellis G. Williams

Kentucky Transportation Center Research Report

A proper quantity of dust particles of various sizes has long been recognized as important in the construction of stone bases and pavements. Screenings for water bound macadam bases are required to contain not less than a specified amount of dust sizes, and dense-graded limestone bases have controlling limits for the dust fraction. It is generally assumed that these particles serve a dual purpose: (1) in filling void spaces created by larger particles, thus enhancing the gross structure of the aggregate, and (2) in acting as a binder material in the presence of water. Furthermore, it has been demonstrated that …

Studies Of The Suitability Of Expanded Shale Aggregate For Use In Cement Concrete, Claude M. Brown Jr., Loren H. Strunk, Dave H. Sawyer

Kentucky Transportation Center Research Report

Expanded shale is one of several artificial lightweight aggregates currently used in the production of lightweight concrete. Its use has become rather widespread through recent improvements in production techniques, mix designs, placement methods, and air entrainment. However, various types of lightweight concrete as such is not of recent origin, having been used in this country for more than a half century.

Expanded shale aggregates are produced by heating a suitable shale to the point of fusion. Gases within the shale expand and thus form thousands of tiny air cells within the mass which are retained upon cooling and solidification. The …

An Investigation Of Bituminous Coatings And Pavements On Corrugated Metal Culverts, Eugene M. West

Kentucky Transportation Center Research Report

The object of this inspection was to determine the efficacy of bituminous coatings and paved inverts on corrugated metal pipe and culverts installed on Rural Secondary Projects during the past few years. The study originated after earlier investigations had led to recommendations concerning the resistance of various types of pipe and culvert materials in the presence of acid-bearing waters.

Blown Mulch For Roadside Erosion Control, Jason C. Taylor

Kentucky Transportation Center Research Report

In May 1954, the Division of Construction brought to the attention of the Research Division the fact that an effort was being made (for the first time in Kentucky) to revise the conventional manner of applying straw mulch to a seeded right-of-way. This innovation was to be achieved with the use of a recently-invented machine known as the "Finn Mulch Spreader", which is capable of mixing a straw mulch with some adhesive substance and then blowing the mixture onto the seeded area. The intent was to achieve a reasonably homogeneous mat-like structure composed of pieces of straw attached to each …

Flexural Properties Of Corrugated Metal Roofing, Howard L. Wakeland

CCFSS Library (1939 - present)

Introduction Roofing materials that combine shelter, fire safety, durability, and strength have largely replaced such historic types of roofing covering as straw, leaves, tile, bark and various wooden coverings. Thus, we have such modern roof coverings as asphalt composition, cement-asbestos, and metal. Of these, metal roofing is used more than any other on farm service buildings. Approximately 40 per cent of present day farm service buildings in the United States are roofed with metal. This proportion continues to increase as more and more metal roofing materials are made available for rural construction. The wide use of metal roofing is due …

Geology Of The Ragged Point Oil Field Musselshell County, Montana, David M. Amos

Bachelors Theses and Reports, 1928 - 1970

The Ragged Point oil field is located in Northwest Musselshell County, in the Lake Basin field of central Mon­tana, and on the western border of the Great Plains region. The surface topography is that of a plain marked by erosion and moderate folding. The stratigraphy of central Montana shows periodic marine invasions from the Cordilleran trough, with normal marine limestones interbedded with sandstone sand shales. These sediments are over 12,000 feet thick, with the Creta­ceous Eagle and Colorado formations exposed at the surface on the Ragged Point anticline. Undifferentiated Cambrian lime­stones and shales are the oldest rocks encountered in drilling.

Effectiveness Of Evaporation From Ground And Foliage In Reducing Soil Moisture Depletion, Val D. Wynn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field irrigation efficiency is the percentage of the water delivered to the field that becomes available to the crop as soil moisture. The so-called "evaporation losses" from wetted ground and foliage are rather difficult to measure, but are estimated by Christiansen (3) to be between 15 and 30 percent. No doubt part of this may be termed as a "loss," but the other part may be incorrectly termed as such. Many authorities claim that water must pass through the plant before being transpired into the atmosphere to be effectively used.

Evaluation Of Sprinkler Irrigation Systems In Northern Utah, Jay M. Bagley, Wayne D. Criddle

Reports

Summary and Conclusions: Sprinkler irrigation will continue to expand in Utah as well as in other irrigated areas of the world. This method of irrigation is suitable to all farm crops grown in the state and to most soils. It is particularly adapted to steep foothill areas where the water supply can be obtained at higher elevation and pumping is not necessary to develop pressure for the sprinkler systems. Also, much of the irrigated land of the state, particularly along the Wasatch front, is owned and operated by "part-time" farmers. Having the water under complete control and the irrigation schedule …

Horizontal Pressures On Retaining Walls Due To Line Surface Loads, John B. Heagler

Masters Theses

"Among the oldest types of structures with which engineers have had to deal are those which serve to laterally restrain masses of earth, or to prevent earth embankments from assuming their natural angle of repose. This is necessary where space is limited or the natural slope would encroach upon other property. These structures, usually called retaining walls, are subjected to forces, both lateral and vertical due to the pressures exerted by the backfill material and any loads imposed on the backfill material. The first step in the design of the retaining wall is to determine the magnitude, position, and line …
