Construction Report On Experimental Use Of Natural, Bituminous, Quartz Sandstone (Kentucky Rock Asphalt) As A Traffic-Bound Aggregate, George R. Laughlin

Kentucky Transportation Center Research Report

Major deposits of natural, bituminous, quartz sandstone (Kentucky Rock Asphalt) occur in six counties of western Kentucky and a few minor deposits occur in eastern Kentucky. Crushed rock asphalt has been used extensively in Kentucky and elsewhere for over 50 years for surfacing roads.* The most productive area was in Edmonson County where the Caseyville and Bee Springs formations were quarried and mined. These deposits have been described as oil-pools which are now defunct and from which only the asphaltic residue remains. The bitumen content of the rock varies locally in a quarry or mine; and, because of this, enormous …

An Analysis Of Traffic Accidents On County Roads, D. F. Petty, H. L. Michael

Indiana Local Technical Assistance Program (LTAP) Publications

The purpose of this research was to investigate the causes of and determine possible remedies for the rising number of county road accidents in Indiana. County road accidents were defined for the purpose of this study as all traffic accidents occurring on roads which are administered by the County Commissioners in Indiana except accidents occurring at intersections of county roads with state highways. These latter accidents are normally charged to state highways. The information used in this research was obtained from accident records. The best available source of this type of information, the accident reports which are filed at the …

Investigation Of Aggregate Occurrence In Logan County, Kentucky, George R. Laughlin

Kentucky Transportation Center Research Report

As requested in your memorandum of September 12, we have conducted an extensive series of tests on the natural sand produced by Kapco Construction Company in Logan County. There was some question regarding the classification of the sand -- whether it would be termed a manufactured, a crushed conglomerate, or a natural sand. I had Mr. George R. Laughlin, Geologist of the Research Division, visit and inspect the pit. A copy of Mr. Laughlin's report to me is attached for your file. He reports that the material being produced is a washed, natural sand and similar in production procedure to …

Laboratory Test Results On Natural Sand Produced By The Kapco Construction Company In Logan County, Ronald D. Hughes

Kentucky Transportation Center Research Report

On September 19, 1962, a sample of sand produced by the Kapco Construction Company was received by the Research Division. This material was sampled at the quarry in Logan County and forwarded to the Research Division by personnel from District No. 3 of the Bowling Green Office. The sample was submitted for laboratory evaluation in regard to possible use of the material as fine aggregate in Class A concrete.

The Monopole Antenna With A Small Number Of Radials, S. H. Durrani

Electrical and Computer Engineering ETDs

This paper reports a study of an antenna system consisting of a vertical monopole and a small number of insulated horizontal radials lying lightly on the ground.

The monopole antenna has long been popular for medium frequency broadcasting because of its inherent simplicity and economy. Although quarter-wavelength resonant structures were used in the early days, it was shown by Ballantine (1924) that for a given power, the strongest field strength at the radio horizon was produced by an antenna about 0.6 wavelength long. This ignored the sky wave and was based on the assumption of a perfectly conducting (and reflecting) …

A Parametric Study Of The Heat Transfer Characteristics Of A Moving Band Heat Exchanger, Larry Hyde Brim

Theses and Dissertations

In recent years much attention has been devoted to the development of efficient heat exchangers. The regenerative or moving matrix heat exchanger is one type which has been considered. Most regenerative heat exchangers use one of the conventional types of high area matrices mounted in a drum or disk in such a manner that it can be moved in a continuous cycle from a cold fluid stream to a hot fluid stream and back again. A rather different approach to the design of a regenerative heat exchanger which has been patented in this country is a set of flexible moving …

Hypersonic Plasma Thermionic Generator, Andre R. Leblanc

Electrical and Computer Engineering ETDs

The Langmuir two-probe system is extended to cover the case of electron emission from one of the probes. The contact potential difference between the two probes is also included as part of the equations. One of the probes, known as the emitter, operates at sufficiently high temperatures such that electron emission occurs, while the other probe, known as the collector, operates at low enough temperatures such that its electron emission can be neglected.

Study Of Light Compaction-Equipment For Maintenance Patching, Robert L. Florence

Kentucky Transportation Center Research Report

Patching pot-holes and resurfacing small areas of pavement entail certain compaction-equipment difficulties for the maintenance crews. Areas in need of repair are often small but may be widely scattered. Large steel-wheeled rollers are difficult to transport from one location to another and tend to bridge across small, deep pot-holes. The bridging effect can be reduced by use of small rollers or pneumatictired rollers, which conform better to the area to be patched. The efficiency of a patching crew depends greatly upon its mobility. The compaction equipment, therefore, should be portable, should conform to the area to be repaired, and should …

Special Provisions For Non-Leafing Aluminum, Basic Lead Silico-Chromate Oil-Alkyd Finish-Coat Paint For Guard Rails And Bridges, William B. Drake

Kentucky Transportation Center Research Report

These provisions cover the material requirements for a pre-mixed, non-leafing aluminum, basic lead silico-chromate, oil-alkyd finish-coat paint which is intended for use in one or two finish-coat applications. This paint is considered to be compatible with undercoat paints currently covered by Special Specification No. 14-56b and may be substituted for the green finish-coat, Para. IV, therein, when so indicated by appropriate notations on the plans, proposals, invitations, etc. This paint may be used for either new or re-paint work on bridges, guard rails, and other steel structures as may be designated. Undercoat paints, when required, shall be in accordance with …

Linear Side-Loaded Transmission-Line Antennas, Robert W. Kulterman

Electrical and Computer Engineering ETDs

A need has arisen in recent years for a mobile transmitting antenna capable of radiating large amounts of power as efficiently as possible in the frequency range from 10 to 40 kc. Several mechanical and electrical problems are encountered in building and operating such an antenna.
