A Proposed Study Of Soils As Related To The Pumping Of Rigid Pavements, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Pumping has been described as, "The process of ejecting the water-suspended subgrade soil from joints, cracks, and the edges of pavement caused by the deflection of the pavement slab under the action of traffic"(4)*. Obviously, the action is limited to rigid or semi-rigid pavements. Hence, the problem is largely concerned with soil and is almost entirely dependent upon properties of the subgrade. During the past five or six years pumping has become the most discussed if not the most important element of highway soils engineering largely because of the increase in heavily loaded vehicles resulting from wartime traffic requirements.

An Evaluation Of Density And Stability Tests On Bituminous Mixes, Cary Burns, L. E. Gregg

Kentucky Transportation Center Research Report

During the past three years the Highway Materials Research Laboratory has experimented with bituminous aggregate mixes in an attempt to determine the densities that can be obtained through certain methods of compaction and the stability of the resulting mixes. The several investigations have resulted in the preparation and testing of approximately six hundred individual samples, most of which were designed to provide information as a guide for specification on particular field projects.

The Mechanical Properties Of Mine Rocks And A Standardized Test Procedure For Their Determination, Walter Edwin Lewis

Masters Theses

"The problem involves studies of the mechanical properties of rocks and was undertaken in an attempt to determine practical data that will help in estimating the supports required to maintain the roofs of mines during and after mining operations. One of the most important problems in mining today is that of the analysis of the action of mine-rock under stresses. From such an analysis in any given mining venture it should be possible to obtain cheaper methods of mining because the supports necessary to maintain the walls and roof of an excavation may be determined on the basis of how …

Nebraska Farm Building Data For North-East Counties Taken From U.S. Census, R. M. Loper

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Fluctuation in the number of farms since the start of the century reflects economic trends, drouth effects and the results of increasing mechanization, particularly since 1935.

The 1945 figures also show the influence of land taken out of production for use as air bases, ordnance plants and ammuition depots. No doubt some of this will be returned eventually to agricultural uses. Since the buildings were removed from this land during the war some new sets probably. will be constructed when individual ownership is obtained again. Such activities present excellent opportunities for developing farmsteads efficiently and attractively arranged; buildings designed to …

Ceramic Properties Of The Clays Of The Polo Gas Field, Clarence Arthur Lambelet

Masters Theses

"In Western and Northwestern Missouri there exist many natural gas fields of such limited size and of such great dispersion that it is not economical to utilize their products by the construction of pipe lines to consuming centers. Thus a large source of natural wealth is lying idle. This wealth could be utilized, however, if some manufacturing process requiring large amounts of fuel were located in the vicinity...The availability of fuel is the reason for interest in the area, though an investigation should be made to assure the quality and quantity of the fuel in any selected area. the adequacy …

Summary Report Of Concrete Investigations In Research Projects C-1, C-2, C-3, And C-17, S. T. Collier

Kentucky Transportation Center Research Report

The data presented in this report were obtained in laboratory investigations of concrete mixes, the majority of which were correlated with Highway Department field projects. Practically all of this information has been recorded in vast reports on individual studies, but here these are combined and summarized in order to facilitate comnarisons between the results from tests similar in nature, and to provide wider distribution of these results.

Of the four research projects considered three were devoted to tests on beam specimens prepared in the field and sent to the Research Laboratory for analyses. The fourth was purely a laboratory study …

A Technique For Making Torsion Balance Surveys Of Inundated Areas, Karl Frederick Hasselmann

Professional Degree Theses

"The need for a technique for making torsion balance surveys of inundated areas was brought to the writer's attention during the years of 1927 to 1933, while employed by The Sinclair Exploration Company to prospect for oil in Austria, Hungary and North and Northwest Germany. At that time, the company was using ten torsion balances, supplementing the work with magnetometer surveys and refraction seismograph detail. During part of this period an elementary and relatively insensitive gravimeter was used. Some reflection seismograph work was also done during the last year of operations. During the course of surveying in North and Northwest …

A Study Of The Separation Of Feldspar From Missouri Granite, Vernon Louis Kasten

Masters Theses

"The greatest use of feldspar is as a flux in the Ceramic Industry where it is used in the manufacture of abrasives, floor tile, terra cotta, china, and earthenware of all types. It is also used in the manufacture of glass and enamels, and much is used as grinding medium in powdered form because it is softer than the common abrasive, quartz...Missouri Granites are composed of feldspar, quartz, mica, and other materials, which may or may not occur in all the samples. It is the purpose of this investigation to attempt a separation of the feldspar from these other components …

The Solubility Of Zinc Ethyl Xanthate In Water, Thomas M. Mckenzie

Bachelors Theses and Reports, 1928 - 1970

A determination of the solubility of zinc ethyl xanthate was attempted by measuring the refractive index of a saturated solution of that salt. The small increment in refractive index effected by adding zinc ethyl xanthate to water in saturation quantities rendered measurements difficult and of dubious accuracy.

The Development Of Ethyl Cellulose Lacquers For Automotive Use : An Ethyl Cellulose Lacquer For Coating Plastics., Robert Carlton Krueger

Electronic Theses and Dissertations

There have been developed various colored ethyl cellulose lacquers that compare favorably with standard nitrocellulose lacquers in physical tests. Ultra violet light caused rather pronounced darkening of the lighter colors such as white and light yellow, probably because of the use of high amounts of phenolic resin. Also because of the presence of relatively large amounts of phenolic resin, the cost was somewhat higher than a comparable nitrocellulose lacquer. Suggestions for further work and improvement are included. An ethyl cellulose lacquer has also been developed to be applied by spray or brush to ethyl cellulose plastics with a minimum amount …

Some Applications Of Statistical Quality Control Methods To The Preparation, Purchase And Calorimetry Of Steam Coal, Arthur P. Bellinghausen

Bachelors’ Theses

This thesis is an attempt to establish the applicability of a statistical method of quality control to several problems involving maintenance of fuel quality standards. Although the technique has found increasingly important applications in mass production industries, its use in analysis of fuel characteristics has been given little, if any, study if current catalogues of the literature are authoritative. Analyses of data drawn from publications of the Bureau of Vines have been used to test the limitations of the method. Original data collected by the author shows statistical control to exist over sufficient samples to assure the soundness of conclusions …

Cornell University School Of Civil Engineering Tests On Light Beams Of Cold-Formed Steel, Cornell University School Of Civil Engineering

CCFSS Library (1939 - present)

I. SCOPE OF THIS REPORT In the Twenty-fifth Progress Report a series of twenty-three tests was reported on web crippling under concentrated loads. On the basis of these tests the design requirements of section 4.9 of the Tentative Specifications (April 1944 edition) were written. The scope of these tests, however, was not broad enough to insure safe design stipulations for all important cases for the following reasons: (a) Of the twenty-three tests six were conducted with roller loading (zero bearing length), and therefore are not represetative of acutal conditions. This leaves only seventeen representative tests. (b) all tests were conducted …
