An Engineering Soil Survey Of Fayette County, Kentucky, Robert C. Deen

Kentucky Transportation Center Research Report

The need for soils data in the site selection, design, construction and maintenance of any major structure is generally appreciated by the engineer. The "rule of thumb" methods often used in developing smaller structures can prove unsatisfactory, or even disastrous, when applied to larger projects.

Operational Characteristics Of A Small Sewage Oxidation Lagoon, Karlheinz C. Muhlbauer

Masters Theses

"With the rapidly increasing population in the United States the adequate disposal of sewage has become one of the major technical problems which the sanitary engineer has to solve. In most areas it is no longer acceptable practice to discharge domestic sewage or industrial waste products directly into streams or lakes because of the resulting pollution of the water, which may later be used for drinking or recreational purposes. Many larger cities have, therefore, adopted some method of sewage treatment which renders such wastes safe and unobjectionable before they are discharged into a lake or stream. Most of these methods …

Location And Economic Study For Interstate Route Tallahassee, Wilbur Smith And Associates

City and Regional Planning -- Florida

The basic purpose of the study was to determine the best location for the construction of an East-West section of the interstate highway. It was prescribed that the work would consist of two basic parts. One had to do with the analysis of travel data, both present and projected, in the determination of the most feasible location of a route based on conventional traffic and highway development factors. The other phase of the work was to deal with economic considerations, especially the economic impact of the proposed routes on businesses located on existing roads and on the central business district …

The geographic limits of the study area are defined as the city limits of Tampa on the north, Tampa Bay on the west, Hillsborough Bay on the south, and U. S. Route 301 on the east. The development of basic planning data and necessary field studies …

An Investigation Of Compressive Testing Of Concrete, Gilbert R. Williamson

Civil Engineering ETDs

The strength of most materials is affected by the rate of application of the load and concrete is no exception. However, the effect of a varying rate of loading on the compressive strength of concrete has not been too fully investigated. This effect is one of the problems covered in this paper. The first investigation along these lines was done in 1917 by Duff Abrams of the Structural Materials Research Laboratory, Lewis Institute, Chicago. In 1936, Paul G. Jones and F. E. Richart, working at the University of Illinois Engineering Experiment Station, reported the result of their experiments of the …

Ten Rural Highway Base Stabilization Projects, James H. Havens, William B. Drake

Kentucky Transportation Center Research Report

During the last week o£ September, 1956, the Division of Rural Highways requested assistance from the Research Division in conducting a series of ten experimental base stabilization projects which were to be geared more-or-less to a practical rural roads development program in which existing soils and local granular materials might be most advantageously treated and stabilized to provide fairly low cost base courses and surfaces, adequate for light rural traffic. The idea of actually constructing a base and bituminous surface for this type of road would represent a refinement over the traditional traffic-bound base type of construction which usually serves …

An Investigation Of High-Strength, Deformed Steel Bars For Concrete Reinforcement, Sidney A. Guralnick, George Winter

CCFSS Library (1939 - present)

INTRODUCTION High strength steel as reinforcement for concrete has received some serious attention by researchers and by the construction industries as long ago as the early 1900' s. Recent developments abroad, notably in Sweden, Germany and Austria, have caused renewed interest in the use of this material in concrete structures. The term "high-strength" is somewhat ambiguous since it usually has been employed to describe the type of steel used in cables and strands for prestressed concrete or suspension bridge structures. Such steels commonly have proof stresses of the order of 200,000 psi. However, in the case of ordinary reinforced concrete …

Temperature Forecasting At Logan, Utah, For The Snowmelt-Runoff Season, Clifton Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this thesis is to investigate the practicability of forecasting temperatures for the spring and summer snowmelt-runoff season. A successful temperature forecast for Logan, Utah, would be useful in studies of Logan River streamflow, as well as other related applications.

Logan, Utah, is situated in a region where the snow accumulates during the winter and early spring at high altitudes and remains until the proper sequence of meteorological events provides the thermodynamic conditions essential for melting. Snow surveys provide an index to the water available on a watershed. Temperature conditions during the melt period largely determine the available …

A Survey Inspection Of Plain Corrugated Metal Pipe Arches And Multi-Plate Metal Pipe Arches In Kentucky, Eugene M. West

Kentucky Transportation Center Research Report

Past observations have indicated that rusting has been rather prevalent in the large, un-paved metal drainage structures most of which have been installed since the opening of the Kentucky Rural Secondary Program in 1949. Since all of these structures are relatively new, and since rusting in any form can be considered a threat to the life of a structure, the Chief Engineer's Office, in 1954, requested that a study be made to determine the over-all frequency possible causes, and individual seriousness of this condition.

Altogether, a total of 86 of these un-paved structures were inspected. Although it would have been …

Physical Properties Of Concrete At Early Ages, Karl H. Dunn

Masters Theses

"There are well over 100,000 miles of concrete pavements existing today on our United States highway system. The development of these pavements during the first half of this century has been a process of learning from construction applications and mistakes. However, the unexpected increase in traffic load has brought highway designers to experiment with relatively new types and designs of concrete pavement construction.

Some designers, in an effort to reduce temperature warping stresses, have used short slabs 10 to 15 feet in length, generally unreinforced. Another type of construction is the definitely jointed slabs, the slabs being from 20 to …

Investigation Of Length Changes In Prestressed Concrete Slabs With Outside Exposures, John Best

Masters Theses

"In general, pavements may be classed as being either rigid or flexible. The term “rigid pavement”, as commonly used in the United States, is applied only to wearing surfaces constructed of portland-cement concrete. All other types of pavements are classed as “flexible”. A pavement constructed of portland-cement concrete is assumed to possess considerable flexural strength which will permit it to act as a beam and allow it to bridge any minor irregularities which may occur in the base on which it rests, hence the term “rigid”….

In view of the experience and information gathered in over 50 years of road …

Investigation Of Length Changes And Warping In Thin Prestressed Pavements, Wilbur D. Stites

Masters Theses

"The present growth of the American highway system presents a staggering problem to the highway designer. The increased and urgent demand for more highways, capable of accommodating traffic loads that are constantly increasing, combined with the increased construction cost of highways, behooves the present day highway designer to envision future highway problems that will arise. These future problems are numerous and complex; however, it seems the primary problem is the selection of a surfacing material that will withstand projected traffic loads with a maximum economy of construction and future maintenance costs. Concrete at the present time is the most satisfactory …

Creep Characteristics Of Thin Prestressed Concrete Slabs, Wayne F. Alch

Masters Theses

"Prestressed concrete as a structural material is finding wider usage in the United States today. Until recently, economic factors have precluded the use of prestressed concrete in this country, while Europe became the leader in discovering new uses and applications in construction for the material. As new methods are developed in this country, more engineers and contractors are discovering that prestressed concrete is, in many ways, far superior to plain or reinforced concrete. In line with this awakening the Missouri Highway Department is carrying on research to determine the feasibility of prestressed concrete for highway slabs. This study is a …

Development Of Rating Curves For Concrete Rebound Hammer On Concrete Specimens From Local Aggregates, Rolla Smith Lush

Masters Theses

"Frequently engineers find it imperative to determine the compressive strength of concrete as it exists in a structure. There are two methods of making this determination, either by a destructive or a non-destructive test. The destructive test has the disadvantage of being costly, time consuming, and detrimental to the appearance of the concrete surface. The non-destructive, pulse-velocity, sonic measuring devices used to determine the compressive strength of concrete in the field also have the disadvantage of high cost due to the large initial cost of the equipment.

A relatively new non-destructive testing device has been developed which may replace the …

The Magnitude And Directions Of Strains And Stresses In Edge Loaded Concrete Slabs, William M. Baldwin

Masters Theses

"The concrete industry in the United States represents one of the fastest growing segments of the national economy. Many reasons for this may be given, among which are, the durability of concrete structures, the local availability of a large portion of the materials used in concrete, and its wide range of adaptability to the designs of engineers and architects.

One of the most recent changes in concrete usage is the change from reinforced concrete to prestressed concrete. The term prestressed as used herein refers to any type of reinforced concrete in which the reinforcing material has a stress prior to …

A Determination Of The Sonic Modulus Of Early Age Concrete, William Dale Nelson

Masters Theses

"The problem which the writer is analyzing in this thesis was suggested by Professor E. W. Carlton of the Civil Engineering Department. It is a determination, by use of sonic testing equipment, of the growth in the sonic modulus of early age concrete.

Since 1938 when T. C. Powers published his paper, "Measuring Young's Modulus of Elasticity by Means of Sonic Vibrations", in the proceedings of the American Society of Testing Materials, Vol. 38, Part II, a great deal of work has been done on the applications of sonic testing of concrete. It began a new era in concrete testing, …

A Comparative Determination Of Weld Shearing Values In Welded Wire Reinforcement Fabric, Ernest Charles Kobs

Masters Theses

"At the suggestion of Professor E. W. Carlton, Chairman, Civil Engineering Department, Missouri School of Mines and Metallurgy, the author selected as subject for research thesis, “A Comparative Determination of Weld Shear Values in Welded Wire Reinforcement Fabric”.

In 1948, the Wire Reinforcement Institute initiated a research program to measure the actual stresses, including weld shear stresses, that occur in Welded Wire Fabric when used as reinforcement in a concrete slab. A great majority of this research was under the supervision of Professor Carlton.

The results of these investigations indicated a wide variation in strength of welds. As a means …
